Are you ready for a pop quiz?

Which bodily component is responsible for producing over 90% of the energy in your body cells, makes up 40% of each heart muscle cell, can change shape to move around when needed, can grow and divide when more energy is required AND can produce hundreds of variations of proteins?

If you guessed mitochondria— ding ding ding — you are correct!

Biology Refresher: Mitochondria 101

Mitochondria convert food into cellular energy in the form of adenosine triphosphate, or ATP, through a process called oxidative phosphorylation. They efficiently break down carbohydrates and fatty acids, producing NADH, an enzyme used to generate ATP. ATP is unique because it cannot be stored and is immediately used as energy for our cells.

Foods that Fuel

While food is essential for mitochondrial performance, avoiding toxins and building muscle mass also play crucial roles.

For instance, even individuals with mitochondrial damage, such as those with Parkinson’s disease, can increase ATP production through strength training, as muscle cells contain more mitochondria.

Genetics also significantly influence mitochondrial function.

Particular diseases such as Alzheimer’s, muscular dystrophy, diabetes, Lou Gehrig’s disease, and certain cancers are linked to genetic mitochondrial dysfunction.

However, diet is a key factor in optimizing mitochondrial function, limiting oxidative stress, and promoting ATP production through essential vitamins, minerals, and amino acids.

CoQ10 is the primary antioxidant in human cells

But what do antioxidants have to do with mitochondria and energy production?

• Oxygen is a critical component in energy production and the oxidative phosphorylation process.
• Antioxidants help protect mitochondria from any damage that can happen during this process – such as any strain on the cell from excess energy use.
• This energy coupling leads to ATP formation as a carrier for both electrons and protons. And (bringing you back to biology 101 again), ATP can be converted into ADP—helping to support energy production further.
• It is recommended that we get between 90-200 milligrams of CoQ10 per day. Foods rich in CoQ10 include soybeans, broccoli, peanuts, fatty fish, and oranges.

Lipoic Acid and Acetyl L-Carnitine work hand in hand to improve age-related decline in mitochondrial bioenergetics

In other words, they aid in the recovery of fatty acids, increasing energy production and metabolic rate while reducing oxidative stress.

• Lipoic Acid plays a crucial role in recharging other important antioxidants for mitochondrial health, like CoQ10 and vitamin E.
• Acetyl L-Carnitine (“L-carnitine”) is an antioxidant that scavenges free radicals and promotes liver detoxification while boosting T-cell activation to help maintain immune function.
• We should strive for between 600-1,800 milligrams of Lipoic acid per day, and about 3g of L-carnitine per day.

Resveratrol induces pro-oxidant effects and antioxidant impact on mitochondria. 

Resveratrol’s benefits to cellular integrity are vast. Here’s how to get more of this invaluable antioxidant:

• Resveratrol improves mitochondrial respiratory activity, boosting cellular reprogramming efficiency and cell growth.
• Resveratrol is in many of our favorite Mediterranean diet foods, including red wine, blueberries, dark chocolate, and peanuts.
• While there is no formal recommended daily dose of resveratrol, in order to see a biological effect, academics suggest a rather large spread of 5mg and 100mg per day.

Vitamin E‘s abundant health benefits

With regard to mitochondrial and cellular health, vitamin E has three key functions:

• Vitamin E prevents thyroid hormone-induced changes
• It significantly reduces the production of free radicals, and
• Vitamin E also elicits beneficial reactions in our cells

Essentially, it is the cell’s first line of defense when it comes to protecting the mitochondrial membrane from the damage free radicals cause.

Aim for 15 mg per day just by simply mixing sunflower seeds, avocado, and kiwi in a smoothie.

Harmful Foods = Malfunctioning Mitochondria

To stress the importance of the above food groups for mitochondrial health, it is essential to understand just the number of functions that the mitochondria in your cells impact.

There are also foods we should avoid in excess, as they can adversely impact mitochondrial function:

Added sugars

Excess sugar is well known to have unfavorable effects on critical functions of our body, most notably our gut and brain health. This is no exception to your mitochondrial health.

Sugar inhibits the mitochondria from quickly burning energy, especially in fructose form. Sugar then winds up being stored as fat and producing damaging free radicals.

Be sure to balance your vegetable intake with the fruit servings in your daily diet and opt for whole fruits rather than processed fruit products.

Refined Carbs

Simple carbohydrates have also been found to be problematic with mitochondrial health.

White flour, when eaten, quickly turns to glucose once digested—it might as well be table sugar.

Mitochondria tend to function better on a lower carbohydrate diet, as they are able to efficiently create energy rather than frivolously burning junk. Try to keep carbohydrates between 225 and 325g daily.

Monitoring your blood sugar levels is an excellent way to optimize your health and well-being. However, some of these metrics are challenging to understand. But by considering the glycemic index and glycemic load, you get a clearer picture of how a typical serving of food will affect your blood sugar levels.

When your body processes glucose, your insulin levels increase to help deliver glucose to your cells, bringing your blood sugar back to normal. If there’s too much glucose, your pancreas produces more insulin, which then converts the excess sugar into fat for storage. Calculating our glycemic index is a helpful way to begin to understand sugar’s effect on our body.

Glycemic Index

The glycemic index (GI) helps us understand how different foods affect our blood sugar levels. It measures how 50 grams of carbs from a specific food can raise your blood sugar. Foods with higher GI scores (from 1 to 100) cause your blood sugar to spike quickly, which is something you want to avoid. Consistent blood sugar levels are better for your overall health. While your brain and body need glucose to function, getting too much too quickly isn’t good for you.

To keep your blood sugar levels steady, focus on eating more low GI foods, which score between 0 and 55 on the glycemic index. Examples include nuts, most vegetables, whole oats, and certain fruits.

You can also enjoy medium GI foods, scoring between 56 and 70, like rice, whole wheat bread, and most fruits. High GI foods, scoring over 71, such as white bread and potatoes, should be eaten sparingly since they can cause rapid blood sugar spikes.

Eating foods that quickly raise your blood sugar levels can lead to more fat storage in your body. The glycemic index helps you choose foods that promote steady blood sugar levels and healthier eating habits.

Glycemic Load

While the GI measures how quickly 50 grams of carbohydrates from a food can raise your blood sugar, the GL goes further by considering the actual amount of carbohydrates in a typical serving of that food.

The GL is calculated by taking the food’s GI, multiplying it by the carbohydrate content (in grams), and then dividing by 100. For a comprehensive list of foods glycemic index values and their glycemic loads, we recommend you refer to the Harvard Medical School Index.

1. Identify the Glycemic Index (GI) of the food, as indicated on a GI chart like this one:

   • For watermelon, the GI is 72.

2. Determine the amount of carbohydrates in a typical serving:

   • One cup of watermelon (154 grams) contains about 11.6 grams of carbohydrates.

3. Use the formula to calculate the Glycemic Load (GL):

   • The formula is: GL = (GI × Carbohydrate content per serving) / 100

   • For watermelon: GL=(72×11.6 grams) / 100

   • The glycemic load of one cup of watermelon is 8.35

The glycemic load is often more reliable than the glycemic index alone. For example, watermelon has a high GI of 72, meaning it can raise blood sugar levels quickly. However, watermelon is mostly water, and a typical serving has a very low carbohydrate content.

Therefore, the GL of a serving of watermelon is only 8.35, which is very low. While watermelon can cause a quick rise in blood sugar, it won’t keep levels elevated for long due to its low carbohydrate content.

To put it in perspective, the GI measures the effect of a standard 50-gram serving of carbohydrates from a food. Eating 50 grams of carbohydrates from watermelon would be unrealistic for most people. One cup of watermelon (about 154 grams) contains approximately 11.6 grams of carbohydrates. You would need to eat over four cups of watermelon to consume 50 grams of carbohydrates.

Putting the Glycemic Load into practice

Here are a few helpful tips to navigate Glycemic Load targets.

When using the glycemic load as a reference for your food, keep in mind that foods between 10 and 15 on the glycemic load are considered moderate.

These moderate GL foods will not keep your blood glucose levels elevated for long periods of time.

However, foods with a glycemic load higher than 15 should be eaten sporadically, as they will spike blood sugar levels and keep them elevated for longer.

Having rapid spikes and consequential decreases will then will cause you to feel unsatiated and fatigued, so be sure to eat these items with protein to even out the spike.

A word of caution: while understanding the glycemic load is important, every person reacts differently to foods, even among very healthy people. For instance, you — an active, individual who eats lots of fresh produce — might have a glucose spike from a cup of watermelon, but your more sedentary friend may not.

The more your glucose levels spike, the higher your chances are of chronic inflammation. The best way to see how your body reacts is to wear a glucose monitor. If you or your members of your family have health-related issues involving blood sugars, talk to your doctor to see if glucose monitoring is appropriate for you.

How is fructose involved?

If you’re wondering how fructose fits into this index, we hear you! It can be hard to talk about glucose without mentioning fructose—take a look at our sugar article.

Unlike glucose, fructose is considered to be a low GI food. With a glycemic index of 19, fructose causes significantly less insulin secretion than glucose. Naturally-occurring fructose is actually ranked lowest on the GI scale of all natural sugars.

High levels of fructose in your body, however, can cause cellular damage— in fact, excess fructose in your body causes seven times more cell damage than excess glucose. This is another reason why you have to be careful when judging foods solely by their glycemic index.

How can I quickly calculate glycemic loads at the grocery store?

Finding the glycemic index (GI) of foods while shopping at the grocery store can be a bit challenging, as GI values are not typically listed on food packaging. However, there are several strategies you can use to access this information:

• Smartphone Apps: There are many apps available that provide GI values for various foods. Apps like “MyFitnessPal,” “Glycemic Index Load,” and “Fooducate” can be very helpful.

• Printed Guides and Books: Some people find it useful to carry a small printed guide or book that lists the GI values of common foods. There are several comprehensive guides available in bookstores or online.

• Online Databases: Before going to the store, you can look up the GI values of foods on websites such as the Glycemic Index Foundation (glycemicindex.com) or other nutrition-focused sites, like Dirt to Dinner in the infographic above!

• Nutrition Labels: While the GI value might not be listed, you can get a sense of a food’s impact on blood sugar by checking the carbohydrate content and the presence of sugars and dietary fiber. Foods high in fiber and low in sugars generally have a lower GI.

• Healthy Eating Lists: You can refer to general lists of low GI foods, such as whole grains, legumes, most vegetables, nuts, and certain fruits. These lists can guide your shopping choices.

By using these resources, you can make more informed decisions about the GI of foods and better manage your blood sugar levels.

Vegetables provide essential vitamins, minerals, and antioxidants that strengthen the immune system, prevent chronic diseases, and reduce inflammation. Failing to include sufficient fruits and vegetables in our diet can lead to nutrient deficiencies, inflammation, poor gut health, weakened immunity, resulting in an increased risk of heart disease, cancer, and obesity.

How do fruits and vegetables impact our health?

It is all about short chain fatty acids!

When you eat fruits and vegetables, they are digested in your gut, where the fibers and polyphenols act as prebiotics, feeding beneficial bacteria such as Bifidobacterium and Lactobacillus. These good bacteria ferment the dietary fibers, producing short-chain fatty acids (SCFAs) like butyrate, propionate, and acetate.

These SCFAs improve the gut barrier by promoting epithelial cell growth and mucus production, preventing pathogens from entering the bloodstream. Additionally, beneficial bacteria compete with harmful pathogens for nutrients and attachment sites, reducing the likelihood of infections.

Feeding these good bacteria boosts immune function by enhancing the activity of immune cells that kill pathogens. SCFAs promote the differentiation of regulatory T cells, which maintain immune balance, and enhance the function of dendritic cells, improving the adaptive immune response.

Beneficial bacteria also stimulate the production of antimicrobial peptides and enhance the activity of natural killer (NK) cells and macrophages, which directly kill infected or abnormal cells. Through these mechanisms, a diet rich in fruits and vegetables supports a robust immune system capable of effectively defending against harmful pathogens.

This guide will explore the top ten most nutrient-dense summer fruits and vegetables, detailing their nutritional benefits, health advantages, and delicious recipes to help you incorporate them into your diet. By understanding the science-backed benefits of these nutrient powerhouses, you can make informed choices that will help you get the most nutritious bang for your diet, supporting overall wellness and vitality.

Go ahead and embrace the natural bounty of summer produce!

A recent study led by Cleveland Clinic analyzed over 4,000 individuals across multiple clinical sites. Data was collected over several years. The study ultimately found there was an association between blood levels of xylitol and an increased risk of heart attack and stroke.

However, the study did not address food intake by participant, so it cannot be determined if the xylitol levels were based on dietary exposure or endogenously-produced xylitol. Ultimately, the study was not comprehensive at evaluating the long-term effects of xylitol when consumed in moderate amounts.

This is a concern as consumers are searching for a sweetener that meets their needs. According to Mintel, “There is an opportunity to help consumers feel informed and in control when making their sugar and sweetener choices.”  Hearing about the downside of an unproven study does not help.

So let’s focus on what we do know about xylitol…

What is xylitol?

Xylitol is a sugar alcohol used as a sweetener in various food and dental care products. It is popular because it has fewer calories than sugar and is known for not causing tooth decay. It is also found in fruit, vegetables, and berries.

Xylitol differs from other sugar alcohols in several key ways, making it unique and beneficial for specific uses. Unlike many sugar alcohols, xylitol has a sweetness comparable to sugar but with significantly fewer calories, making it a popular sugar substitute. It is particularly noted for its dental health benefits; xylitol helps prevent tooth decay by inhibiting the growth of Streptococcus mutans, the bacteria primarily responsible for cavities.

Additionally, xylitol has a lower glycemic index than other sugar alcohols, which means it has a minimal impact on blood sugar levels, making it a suitable sweetener for diabetics and those managing blood glucose levels.

While other sugar alcohols can cause digestive discomfort in large quantities, xylitol is generally better tolerated, though it can still cause issues for some individuals if consumed in excess. Overall, xylitol’s unique properties make it a versatile and advantageous sugar alcohol for both health and culinary purposes.

Products commonly containing xylitol:

• Gum: brands like Orbit, Trident, and Eclipse
• Sugar-free candy and mints: Brands like Werthers, Ice Breakers, and Spry
• Sugar-free or low-sugar baked goods
• Dental products, like toothpaste and mouthwash
• Over-the-counter medications and chewable vitamins
• Low-calorie foods and beverages, like gelatin desserts, condiments, and cereals

Cardiovascular implications

The researchers found a correlation between higher levels of xylitol in the bloodstream and an elevated incidence of these serious cardiovascular health issues outlined below. The study authors hypothesized that xylitol might influence cardiovascular health through mechanisms that are not yet fully understood, warranting further investigation.

Blood clotting

One possible explanation, according to the results, is that xylitol could affect platelet function, which plays a crucial role in blood clotting. Altered platelet activity might increase the likelihood of clot formation, leading to heart attacks or strokes.

Metabolic pathways

Xylitol is also metabolized differently from regular sugar, and this unique metabolic pathway might impact lipid levels, inflammation, and other factors involved in cardiovascular health.

Impact on blood vessels

There is also speculation based the study that xylitol could influence the health of blood vessels, potentially contributing to atherosclerosis (the buildup of fats, cholesterol, and other substances in and on the artery walls). Again, more research is needed here as to the exact levels that can cause these impacts, and over what span of time.

 

Xylitol’s other health effects

Dental benefits

 

Cavity prevention: Xylitol is well-documented for its role in preventing tooth decay. It inhibits the growth of Streptococcus mutans, the bacteria primarily responsible for cavities, by reducing their ability to stick to teeth and produce acid.

Saliva production: Xylitol stimulates saliva production, which helps in neutralizing acids and repairing tooth enamel.

 

Glycemic control

 

Lower glycemic index: Xylitol has a low glycemic index, making it a popular sugar substitute for people with diabetes. It does not cause significant spikes in blood glucose or insulin levels, which is beneficial for blood sugar management.

Weight management: Due to its lower calorie content compared to regular sugar, xylitol can be useful in weight management and reducing overall calorie intake.

 

Digestive issues

 

Laxative effect: At high doses, xylitol can cause digestive discomfort, including bloating, gas, and diarrhea. This is because it is partially absorbed in the small intestine, and the unabsorbed portion is fermented by bacteria in the large intestine, producing gas. Eating more than 30-40 grams of Xylitol is harmful.

Tolerance levels: Individual tolerance to xylitol varies, and some people may experience gastrointestinal issues even at lower doses.

Allergic reactions: While rare, some individuals may have allergic reactions to xylitol, manifesting as rashes, itching, or gastrointestinal distress.

 

Debunking misconceptions

A common misconception is that all sugar-free options are inherently bad for health. This is not true. Sugar-free products are often great low-calorie options for those looking to lose or maintain weight; they also can serve as insulin stabilizers.

However, be aware of how much of these substitutes you consume and their potential long-term health effects over time. There is currently no limitation nor recommendation on the amount of xylitol that is considered safe for consumption.

Balancing benefits and risks

While it offers significant advantages for dental health and blood sugar control, the recently published study needs to be investigated more thoroughly to determine if there is a real risk. So, what can we do?

Moderation is key

While the study does not specifically support moderation, and does not detail how much we should eat, we do know that any sugar can have adverse effects if eaten in too great a quantity causing inflammation, digestive issues, obesity, metabolic disorders, and so on. Remember for regular sugar, the recommended maximum daily intake should not exceed 9 teaspoons for men and 6 teaspoons for women.

Stay informed

Keep up-to-date with new research on sugar substitutes and their health effects. As more studies are conducted, guidelines on safe consumption levels may evolve.

Have a colorful and varied diet

Eating fruits, vegetables, and protein instead of excess sugar is crucial for maintaining a healthy and balanced diet. Fruits and vegetables are rich in essential vitamins, minerals, antioxidants, and dietary fiber, all of which are vital for overall health.

These nutrients help to boost the immune system, reduce the risk of chronic diseases such as heart disease and cancer, and improve digestive health. Additionally, fruits and vegetables are a great low in calorie option and high in water content, which can aid in weight management and promote a feeling of fullness.

Consuming adequate protein is important for metabolic health, as it helps regulate appetite and stabilize blood sugar levels. Unlike sugary foods, which can lead to spikes in blood sugar and contribute to weight gain and metabolic disorders, protein-rich foods promote satiety and sustained energy levels.

Use common sense

But don’t fret. You certainly are not going to have adverse effects from chewing gum or brushing your teeth given how little xylitol is in these products. Now, eating 5 sugar-free processed muffins daily for an extended period of time might not be the best idea…but that’s for several reasons. Focus on nutrient dense whole fruits, vegetables and proteins!

You have many choices to satisfy your sweet tooth besides sugar. In fact, almost half of us use sugar alternatives, with 43% turning to sugar substitutes to curb their sugar consumption.

Among sugar substitutes, artificial sweeteners such as Splenda, Equal, and Sweet’N Low are 2023’s most popular choices, with natural alternatives, like Stevia in the Raw and other stevia products, gaining in market share.

Despite our persistent beliefs about how unhealthy these sweeteners are for us, all artificial and natural sweeteners on the market in the U.S. and Europe are Generally Regarded as Safe (GRAS) by the FDA and tested thoroughly by the European Food Safety Authority and the WHO.

Because of the meticulous analysis conducted by such governmental organizations as the FDA, WHO and the European Union, we as consumers can feel confident that these sweeteners have undergone substantial scrutiny before consumption of these products is permitted.

Don’t sweeteners make us sick?

Artificial sweeteners, Splenda, Equal and Sweet’N Low, have a very storied past with the public, with about 40% of us believing sweeteners are generally unhealthy and also that some sweeteners are worse than others. These beliefs are a contributing factor to the recent decline in sales of artificial sweeteners and its associated products, like diet sodas.

Saccharin, the first artificial sweetener on the market, came under scrutiny in the 1970s because of a well-known lab test among rats that resulted in an increased incidence of bladder cancer. However, the results were later dismissed as it was found that saccharin has an entirely different effect on human bladders.

Aspartame continues to have its share of the spotlight with similar cancer concerns, mostly of the brain, but in 2006 the National Cancer Institute conducted a 5-year study of data from almost 500,000 individuals and found that higher levels of aspartame were not associated with elevated risk for brain cancer.

The agony and the irony

Surprisingly, some of these artificial, no-calorie sweeteners we use to lose or manage our weight are making us bigger, depending on the amount and duration we use them.

There is a tremendous amount of controversy on how these artificial sweeteners contribute to obesity. It is debated within the scientific community whether regular, long term consumption of artificial sweeteners leads to long-term health benefits or weight loss.

In fact, quite the opposite can be true: a 2017 meta-analysis reported in the Canadian Medical Association Journal found that the consumption of sugar substitutes was associated with increases in weight and waist circumference, and a higher incidence of obesity, hypertension, metabolic syndrome, type 2 diabetes and cardiovascular events.

So if sweeteners have zero calories, how in the world is this happening? There may be three reasons for the expanding waistlines and associated illnesses…

Sweetness begets more sweetness

Dr. David Ludwig, an obesity and weight-loss specialist at Harvard-affiliated Boston Children’s Hospital, hypothesizes that those who use artificial sweeteners may end up replacing the lost calories with less nutritious and calorie-dense options, like cake or pizza, thinking that they can “spend” their otherwise consumed 300 calories if they drank two regular sodas.

Another consideration is that hyper-sweetened substances may alter the way we taste our food. Since sucralose is 600 times sweeter than sugar, our brains become more accustomed to this level of sweetness and eventually we find more natural but lesser sweet things, like fruits, less desirable. And vegetables? Forget it!

Lastly, these artificial sweeteners allow the consumer to disassociate sweet with caloric, which can be dangerous as eating sugar and sugar-like substances signal our brain to consume more sugar, thus initiating a vicious cycle. You can blame that on our primate ancestors, as sugar was a scarce commodity way back when!

Other controversies

While the research has not been peer-reviewed or widely accepted by the scientific community, there are several separate research trials of Splenda, Equal, and Sweet’N Low that have shown causal relationships between artificial sweeteners and negative gut microbiome health, stroke and Alzheimer’s disease.

One study conducted by a team of Israeli scientists in 2014 found that artificial sweeteners, such as sucralose, aspartame and saccharin, significantly altered the intestinal bacteria of mice that, in turn, negatively affected their metabolisms, leading to obesity, diabetes, and other related diseases. (If you are unfamiliar with the gut microbiome, also known as our “second brain”, be sure to read our post on gut microbiota.)

Regarding the link of artificial sweeteners to Alzheimer’s disease and stroke, the American Heart Association reported that daily consumption of diet sodas may substantially increase the risk of these diseases. However, it is important to keep in mind that this finding may be a correlation and not causation— meaning that those who drink diet sodas regularly may be in poorer health than those who don’t drink them due to overall poor diet and lack of exercise.

Do diet drinks count?

Some of us may not think we regularly use artificial sweeteners, but don’t discount all those diet drinks and zero-calorie flavored waters!

According to a 2016 study published in the Journal of the Academy of Nutrition and Dietetics, nearly half of adults and a quarter of children in the U.S. consume artificial sweeteners—and the majority do so on a daily basis, with diet drinks making up the bulk of the intake.

Both the American Heart Association and the American Diabetic Association jointly agree that people should use artificial sweeteners cautiously.

Other options are also being added to the grocery store shelves, such as xylitol and stevia-sweetened sodas and drinks.

Because of its taste and its natural origin, stevia sweetened sodas, drinks, and food items are gaining in popularity.

From just 2014 to 2017, the market value of stevia has grown 71% to $578 million from $338 million.

Here’s a list of the most popular diet drinks in the market today and their associated sweeteners:

Splenda (sucralose)

Splenda is an artificial sweetener that is made of sucralose, a synthetically derived compound from sucrose – or table sugar. Sucralose is extremely sweet – it’s about 600 times sweeter than table sugar and three times sweeter than Equal.

Sucralose in your body: Because your body has no use for it, approximately 85% of sucralose does not get digested or absorbed, thus leaving your body unchanged. Most of what remains gets absorbed in the gastrointestinal tract and then leaves the system as urine, but about 5% of the remaining sucralose will metabolize in the body.

Limitation on consumption: As per FDA guidelines, acceptable daily intake of sucralose is 5 milligrams per kilograms of body weight per day. So if you weigh 150 lbs., it is safe for you to consume upwards of 340mg of sucralose per day, which equates to 28 Splenda packets or 9 cans of diet soda. That should leave PLENTY of room for even the sweetest of sweet-tooths! 

Equal (aspartame)

Equal, or aspartame, is made from aspartic acid and phenylalanine, two amino acids that when combined in a specific structure, yield a very sweet substance that’s 200 times sweeter than table sugar.

Aspartame in your body: Unlike sucralose and saccharine, aspartame is fully absorbed in the body given its composition of amino acids, which your intestinal tract breaks down into digestive enzymes the same way it would after consuming common protein sources, such as meats, fish, eggs and dairy. Aspartame does not enter your blood stream. 

Limitation on consumption: The acceptable daily intake of aspartame as determined by the FDA is 50 milligrams per kilograms of body weight per day. So if you weigh 150 lbs., it is safe for you to consume upwards of 3,400mg of aspartame per day. This equates to 18 cans of diet soda or almost 100 blue packets…per day! Keep in mind that your body creates trace amounts of methanol when breaking down aspartame. Though small amounts are not considered toxic and are actually naturally-occurring, larger amounts can lead to headaches, weakness, dizziness and nausea.

Aspartame and health conditions: A very important note about aspartame is that it is not to be consumed by those who suffer from phenylketonuria, a condition in which a person cannot metabolize phenylalanine into tyrosine. Thankfully, in the U.S. and most countries, detection of this condition occurs in the newborn screening panel.

Sweet’N Low (saccharin)

Sweet’n Low is an artificial sweetener made of saccharin, or benzoic sulfimide, which is a synthesized compound of methyl anthranilate, sodium nitrite, hydrochloric acid, sulfur dioxide, chlorine, and ammonia. This yields a very sugary substance that’s 300-400 times sweeter than sucrose. 

Saccharin in your body: Similar to sucralose, saccharin is also not largely stored in the body.

Limitation on consumption: As per FDA guidelines, the acceptable daily intake of saccharin as determined by the FDA is 15 milligrams per kilograms of body weight per day. So if you weigh 150 lbs., it is safe for you to consume upwards of 1,000mg of saccharin per day, which equates to 28 pink packets or 16 cans of Tab (if you’re able to locate the cult fave!)

Stevia

Stevia is an all-natural sweetener that comes from a shrub called stevia rebaudiana and is primarily grown in South America and Asia. Today, 80% of all stevia comes from China, where they practice strict farming guidelines. These compounds are so sweet that it is actually 200-300 times sweeter than sugar.

Stevia in your body: Stevia has been studied and confirmed that it does not change your glycemic index or glycemic load. Research shows that it is metabolized by the liver, then passes through the body and does not accumulate anywhere.

Limitation on consumption: As per FDA guidelines, the acceptable daily intake of stevia is 4 milligrams per kilograms of body weight per day. So if you weigh 150 lbs., it is safe for you to consume up to 40 packets of stevia per day – every day.

A more “natural” artificial sweetener? There has been some conversation about stevia being considered a natural sweetener. Because there is no real definition of ‘natural’ (read our post investigating the ‘natural’ label here), the word is not meaningful. However, it is not synthetically made like other alternative sweeteners; therefore it is referred to as a ‘natural-origin’ sweetener.

This method, developed by Will Coleman, not only simplifies the shopping process but ensures that consumers maintain a balanced diet rich in essential nutrients. This approach aligns well with the Dirt to Dinner philosophy, emphasizing wallet-friendly trends, beneficial for health, and helpful in making informed, healthful, consumer decisions.

Shopping Method Countdown

The 6-to-1 grocery shopping method is a strategic approach to grocery shopping that encourages shoppers to purchase items across six distinct categories for every one discretionary item: 6 vegetables, 5 fruits, 4 proteins, 3 starches, 2 spreads and 1 treat.

The focus is on filling the cart with essentials that ensure a well-rounded ratio of nutrients, thereby simplifying decision-making.

So let’s start from the top…

Six Vegetables

Choose six vegetables to put in your cart!

The recommended daily intake of vegetables can vary based on factors like age, sex, and level of physical activity, but a general guideline from health authorities such as the U.S. Department of Agriculture (USDA) suggests that adults consume between 2 to 3 cups of vegetables per day. This is part of their broader recommendation for a healthy eating pattern.

For instance, specific guidelines suggest:

• Women aged 19 to 50 years should aim for at least 2.5 cups of vegetables daily.
• Men in the same age range should target at least 3 cups daily.
• Older adults or those less physically active might need slightly less.

These servings should include a variety of vegetables from different subgroups, including dark green, red and orange, legumes (beans and peas), starchy, and other vegetables, to ensure a diverse intake of nutrients.

Here are some of our favorite nutrient-dense options that are tasty in all sorts of recipes:

Health Benefits: Sauces and spreads can enhance the flavor of meals while contributing to nutrient intake. For example, olive oil in pesto is rich in monounsaturated fats, which are beneficial for heart health and may reduce the risk of heart disease.

One Fun Treat

While generally limited in nutrients, allowing for occasional treats like dark chocolate can aid in sticking to a healthy eating plan by reducing feelings of deprivation. Dark chocolate is known for its cardiovascular benefits due to its high flavonoid content.

Here are a few treat examples and nutrients:

• Square of dark chocolate: Flavonoids, iron, magnesium
• Pack of sugar-free gummy bears: Sugars, small amounts of juice (if used)
• A small serving of corn chips: Sodium, calories

By organizing shopping into six straightforward categories, Coleman’s method helps individuals make healthier food choices, reduce food waste, and save money—all of which are essential for maintaining a balanced diet and lifestyle in today’s fast-paced world. The method not only supports physical health by ensuring a nutritious diet but also promotes mental well-being by simplifying decision-making and reducing the stress associated with meal preparation.

Coffee gives us a great morning boost – and it is not just the caffeine! A recent study published in Nature Metabolism brings to light the significant role of trigonelline, a naturally occurring compound in coffee, in enhancing muscle health and function, particularly against the backdrop of aging.

Trigonelline is an alkaloid that serves as a precursor to NAD+. This molecule is crucial for energy production in cells, particularly within mitochondria — the powerhouses of cells.

New Research on Trigonelline

As we age, our mitochondria’s efficiency in energy production wanes, partly due to declining NAD+ levels. This decline is linked to several age-related conditions, including sarcopenia, which is characterized by the loss of skeletal muscle mass and strength.

Think of trigonelline in the body like a key that unlocks the energy production factory in muscle cells. Just as a key starts a car and revs the engine, trigonelline helps turn on the mitochondria, boosting energy output and enhancing muscle function, especially as we age. This ensures the body’s engines run smoothly and efficiently.

The implications of these findings are vast.

For one, it suggests that daily consumption of coffee, a rich source of trigonelline, could offer a simple, natural way to support muscle health and mitigate some aspects of aging.

The study, however, does not specify the exact amount of coffee required to achieve these benefits, as trigonelline content can vary widely among different coffee types and preparations.

Generally, a moderate intake of black coffee (approximately 3-4 cups per day) is considered beneficial for most people, but individual responses can vary.

Debunking Myths

But what about coffee’s negative effects? Does the trigonelline make up enough for them?

First, let’s dispel some of these outdated coffee myths:

⊗   Coffee causes dehydration

• While caffeine has a mild diuretic effect, the fluid content in coffee helps to maintain hydration levels. Studies suggest that for regular coffee drinkers, this diuretic effect is minimal.

⊗   It causes heart disease

• Numerous studies have shown that moderate coffee consumption does not increase the risk of heart disease. In fact, some research indicates that it may have protective effects against certain cardiovascular issues.

⊗   It’s addictive

• While caffeine can be mildly habit-forming, it does not stimulate the brain’s reward circuitry in the same way as addictive drugs. Most people can manage or reduce coffee consumption without the severe withdrawal symptoms associated with true addiction.

⊗   It stunts growth

• Scientific evidence does not support the idea that coffee consumption affects growth. This myth may have originated from the misconception that coffee causes osteoporosis, which it does not when consumed in moderation.

⊗   It causes cancer

• In 2016, the World Health Organization moved coffee off its “possible carcinogen” list, acknowledging the lack of evidence that coffee causes cancer. Some studies suggest that coffee may even reduce the risk of certain types of cancer.

Coffee Health Facts

And there are plenty of other reasons to enjoy your cup of joe, in addition to minimizing muscle loss.

♥   Antioxidants

• In addition to trigonelline, coffee is rich in powerful antioxidants, like chlorogenic acid and caffeine, which can neutralize harmful free radicals. This antioxidant activity is linked to a reduced risk of diseases such as heart disease and certain cancers.

♥   Caffeine

• As the most well-known active ingredient in coffee, caffeine has been studied extensively. It’s known to enhance brain function, improve mood, and boost metabolism. A study published in “The American Journal of Clinical Nutrition” suggests that caffeine can increase metabolic rate by up to 11% and enhance physical performance.

♥   Chlorogenic Acid

• This is another significant component, believed to help lower blood sugar levels and potentially reduce the risk of type 2 diabetes. A study in “The Journal of Nutrition” found that chlorogenic acid might improve glucose metabolism, which is crucial for managing diabetes.

♥    Magnesium & B Vitamins

• Coffee contains essential nutrients, including magnesium and B vitamins, which play crucial roles in numerous bodily functions, including energy metabolism and DNA repair.

It’s also worth noting that while coffee’s potential health benefits are promising, it’s important to consume it in moderation and be mindful of individual tolerance levels. Additionally, the healthiest way to enjoy coffee is black, or with minimal added sugar, to avoid counteracting its benefits with unnecessary calories.

This study, a collaboration among international researchers, underscores the potential of dietary interventions to improve health outcomes, especially in aging populations. It opens doors to further research on trigonelline’s role in human health and its potential in dietary supplements or as part of a broader strategy to combat age-related muscle decline.

Reputable Sources for Food Info

How do these myths and truths come to exist in people’s minds? It is all about the source.

These sources, like Dirt to Dinner, are grounded in scientific research and peer-reviewed studies, and offer reliable and evidence-based insights, ensuring the advice you follow is beneficial for your health. They help sift through myriad information available, distinguishing between evidence-based facts and unfounded claims to help eliminate unfounded myths such as these.

This careful approach to gathering information is essential for making informed decisions about your diet and health, contributing to a well-rounded understanding of nutrition’s role in overall well-being and helping to navigate through common myths and misconceptions.

Chipotle’s ambitious initiative to embrace and invest in the future of food through its $100 million Cultivate Next venture fund demonstrates a forward-thinking approach to the customer experience and increases access to real food.

“Our decision to double our commitment to our Cultivate Next venture fund is a clear indicator that we are investing in the right companies that we can learn from and utilize to improve the human experience of our restaurant teams, farmers, and suppliers,” said Curt Garner, Chief Customer and Technology Officer, Chipotle. Garner continues:

Technologies in play

The significant investments in the fund include Hyphen. The Hyphen robot represents a joint venture between Chipotle and Hyphen, aiming to revolutionize how Chipotle prepares its bowls and salads. These menu items, which form a large chunk of Chipotle’s online orders, are assembled with the help of an automated system that accurately dispenses ingredients into dishes as they move along a lower conveyor belt.

This innovative approach is designed to boost order preparation speed and precision, freeing staff members to dedicate more time to customer interactions and other essential duties. Currently under evaluation, this technological enhancement seeks to refine Chipotle’s digital service capabilities and elevate the overall dining experience for its customers.

Another fund component is an investment in GreenField Robotics, which is revolutionizing farming practices with its innovative approach to regenerative agriculture. The company leverages artificial intelligence, robotics, and sophisticated sensors, to deploy autonomous robots that manage weeds in crop fields without harmful chemicals.

These robots are designed to operate day and night, navigating between rows of crops to target and remove weeds precisely, thus significantly reducing the reliance on traditional herbicides. This method supports the health of the soil and the ecosystem and presents a sustainable and cost-effective alternative to conventional farming methods.

Nitricity is another component of the innovation investment. Nitricity is a company that produces nitrogen fertilizers through a sustainable and innovative process. This process involves creating “artificial lightning” to break down nitrogen from the air, which is then combined with rainwater to form nitrate, a natural fertilizer. This method is inspired by the natural process where lightning breaks atmospheric nitrogen into nitrates that nourish the soil.

Nitricity’s approach aims to reduce greenhouse gas emissions associated with traditional nitrogen fertilizer production methods, such as the Haber-Bosch process, which is energy-intensive and relies heavily on fossil fuels. The investment aligns with Chipotle’s sustainability goals and commitment to enhancing food integrity throughout its supply chain.

By incorporating Nitricity’s climate-smart fertilizer into its agricultural practices, Chipotle aims to support more sustainable and environmentally friendly farming practices.

The Meati Foods investment enhances Chipotle’s menu with sustainable plant-based protein options that are aligned with its Food with Integrity standards. Using a fermentation-based process, Meati develops alternative proteins derived from mushroom roots, specifically mycelium. This method results in products that mimic chicken and steak in texture, flavor, high protein, high fiber, and no cholesterol.

Cultivated indoors, Meati Foods ensures its products are grown clean and free from common agricultural contaminants. Through the “Eat Meati” brand, the company is committed to offering nutritious, whole-food options that are environmentally friendly.

Zero Acre Farms is a food company focused on healthy, sustainable oils and fats that is on a mission to end the food industry’s dependence on vegetable oils. The company has introduced a new category of healthy oils and fats made by fermentation that are more environmentally friendly. Chipotle is in the early trials of testing Zero Acre Farms at its Cultivate Center test kitchen in Irvine, California.

Industry Players Invest in Fast Food’s Future

Several other fast-food companies invest significantly in food innovations, leveraging technology to address global challenges such as food security, affordability, and safety. These companies are exploring various technologies, including artificial intelligence, robotics, sustainable packaging, plant-based alternatives, and blockchain for supply chain transparency.

Here’s a list of notable players alongside Chipotle that are actively investing in the future of food:

• McDonald’s is incorporating AI learning into its operations, making strides in the alternative packaging space, providing plant-based options, and investing in improved supply chain technologies—all ways that they are investing in and prioritizing health and sustainability.
• KFC is experimenting with 3D bioprinting technology to create lab-grown chicken nuggets to offer more sustainable and ethical meat options.
• Domino’s Pizza uses drones and autonomous vehicles to reduce delivery times and costs.
• Burger King focuses on sustainability through initiatives like reducing greenhouse gas emissions and offering plant-based burger options like the Impossible Whopper, made from soy leghemoglobin, the same ingredient in the Impossible Burger, to cater to a broader range of dietary preferences.
• Starbucks invests in sustainable practices, including efforts to reduce waste and water use. It is also exploring plant-based menu items to provide more environmentally friendly and healthier options.
• Wendy’s utilizes food safety and quality assurance technology, implementing advanced tracking and monitoring systems in its supply chain.
• Taco Bell is innovating its menu to include vegetarian and low-impact food options, aiming to make the fast-food industry more inclusive and sustainable.

Impact of Innovations on Food System

Why should we care about the investments these companies are making? The impact spreads far beyond the decision of “what’s for lunch today” and will untimely touch our children’s and their children’s lives.

Food Security: Innovations, especially in plant-based proteins and lab-grown meats, can significantly contribute to food security by providing alternative sources of nutrition, ensuring a stable food supply in the face of growing global demand and environmental challenges.

Affordability: Automation and AI in food preparation and delivery can lower operational costs, potentially making food more affordable for consumers. These companies can offer competitive pricing while maintaining quality by optimizing supply chains and reducing waste through better inventory management.

Safety: Technological advancements such as blockchain for transparent supply chains and AI for monitoring food quality can enhance food safety. These technologies allow for better tracking of ingredients from farm to table, ensuring that food meets health standards and reducing the risk of contamination and foodborne illnesses.

Answering a Call-to-Action by Consumers

These investments also answer a call from consumers, who, in recent years, have put the majority of the onus on food companies to lead the way for positive change. Today’s consumers are increasingly conscious of their food choices’ health, environmental, and social impacts. This heightened awareness drives demand for healthier, more sustainable, affordable food options. Consequently, consumers rely on food companies to make significant investments and changes to meet these expectations.

Consumers are seeking convenient, nutritious options tailored to various dietary needs, such as low-calorie, low-fat, plant-based, and allergen-free options. They expect food companies to innovate to reduce the use of artificial ingredients, preservatives, and high sugars and fats without compromising taste or affordability.

There’s also a growing demand for food produced in an environmentally friendly and ethically responsible manner. Consumers are looking for companies that invest in sustainable agriculture practices, reduce greenhouse gas emissions, minimize water usage, and ensure animal welfare. They are also increasingly interested in local sourcing and reducing food miles. Moreover, sustainable packaging solutions to reduce plastic waste are critical to consumer choices.

While consumers strongly desire healthier and more sustainable food options, they also demand affordability. The challenge for food companies is to balance the cost of implementing innovative and sustainable practices with the need to keep prices accessible to a broad audience. This requires efficient production and distribution practices and, sometimes, rethinking entire supply chains to maintain competitive pricing.

To build and maintain consumer trust, food companies must be transparent about their practices, including sourcing, ingredient lists, nutritional information, and environmental impacts. Technology, such as blockchain, often facilitates this transparency by tracing the journey of food from farm to table, assuring consumers of the quality and safety of their food.

In response to these consumer expectations, food companies increasingly invest in research and development to create new products that meet these criteria. Companies like Chipotle are adopting innovative technologies to improve food production efficiency, exploring alternative ingredients to make their products healthier and more sustainable, and reevaluating their supply chains to increase transparency and reduce environmental impact.

These investments are not only a response to consumer demand but also an acknowledgment of food companies’ role in addressing global challenges like climate change, health issues, and food security. By aligning their strategies with consumer expectations, food companies can ensure long-term viability and contribute to a more sustainable and healthy food system.

You know those moments when you’re faced with a gooey chocolate chip cookie or a crispy slice of bacon, and it feels like your brain is staging a full-blown rebellion against your dieting efforts? Well, it turns out there’s some fascinating science behind why these irresistible foods have a hypnotic hold over us.

Picture your brain as a bustling city with a network of roads. Now, imagine the flow of traffic on these roads is the signals sent by your gut, specifically, the vagus nerve. This nerve is like the messenger between your tummy and your brain, and its job is to tell your brain what’s going on in your belly.

For the longest time, scientists were like detectives trying to crack the case of why we’re so drawn to unhealthy foods. They were on a mission to discover the secret behind our food cravings. But the real puzzle was this: why do our brains go crazy over fats and sugars, especially when they team up in delightful duos like donuts or cookies?

What does new research reveal?

In the February 2024 issue of the Monell Chemical Senses Center‘s Cell Metabolism Journal, a team of scientists unraveled this culinary enigma. They discovered that it all starts in our gut, not in our taste buds.

You see, there are dedicated pathways in our vagus nerve for various things, including a pathway for fats and another for sugars, that act like separate lanes on that culinary highway we talked about. When you munch on something fatty, the fat pathway lights up like a neon sign in Las Vegas, and when you indulge in something sweet, the sugar pathway does a little happy dance.

Now, here’s where it gets even more interesting. Imagine these pathways as two separate party invitations: one for fats and another for sugars. When you’re at a party, you’re having fun, right? Well, our brain is no different. It enjoys these food parties, too. But here’s the kicker – when you combine fats and sugars, it’s like sending out a double invitation to the brain’s ultimate party central.

These two pathways join forces, and your brain responds with a surge of dopamine, the pleasure chemical, making you want more of that irresistible combo.

But don’t despair! There’s a glimmer of hope on the horizon. The scientists behind this discovery believe that understanding this gut-brain connection could lead to some pretty cool strategies and treatments. By tinkering with these pathways, we might have a shot at making healthier food choices, even in the face of those devilishly tempting treats.

So, the next time you find yourself eyeing that mouthwatering chocolate cake, remember: it’s not just about will power; it’s a brain party happening on a microscopic level. And while the battle between your taste buds and your brain rages on, science is on the case, working to help you make healthier choices without sacrificing all the delicious fun.

Issues with overindulging

Overindulging in foods rich in sugar and unhealthy fats can have serious health consequences. One of the most immediate risks is weight gain, as these foods are often calorie-dense.

Weight gain can contribute to obesity, a significant risk factor for various health problems such as heart disease, type 2 diabetes, and certain cancers.

Liver health can be compromised by high sugar intake, particularly fructose found in common sweeteners like table sugar and high fructose corn syrup. This can lead to non-alcoholic fatty liver disease (NAFLD), which may progress to more severe liver problems.

Mental health can also be impacted, as sugar and fat-rich diets can cause mood swings, irritability, and even symptoms of depression.

Inflammation is another concern associated with these diets, contributing to conditions like arthritis, autoimmune diseases, and a heightened risk of certain cancers.

Dental health is affected by excess sugar consumption, as it provides a breeding ground for bacteria in the mouth that produce acids, leading to tooth decay and gum disease.

Additionally, excessive sugar intake can disrupt the balance of gut bacteria, potentially leading to digestive problems.

Tips to combat The Urge

While the scientific discoveries about our brain’s response to fats and sugars are fascinating, you don’t have to surrender to your cravings. Here are some practical tips to help you combat the effects of these food temptations:

Be Mindful of Portions

• Instead of completely avoiding your favorite treats, practice portion control. Enjoy a small piece of that chocolate or a single bite of your favorite high-fat snack. Savor the flavor without going overboard.

Diversify Your Diet

• Make sure your meals are balanced and include a variety of foods. Incorporate plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats into your daily meals. This can help reduce the intensity of your cravings for high-fat, high-sugar items.

Stay Hydrated

• Sometimes, thirst can be mistaken for hunger. Before reaching for that sugary or fatty snack, have a glass of water. Staying hydrated can help reduce cravings.

Plan Your Indulgences

• Designate specific times or days when you’ll allow yourself to enjoy your favorite treats. Knowing that you have a treat coming up can make it easier to resist spontaneous cravings.

Keep Temptations Out of Sight

• If you have a weakness for certain foods, try not to keep them readily accessible at home or in your workspace. Out of sight, out of mind!

Get Moving

• Exercise can boost your mood and reduce cravings. So, when you’re hit with a craving, take a brisk walk or do a quick workout to distract your mind.

Mindful Eating

• Pay attention to what you’re eating and savor every bite. Eating mindfully can help you enjoy your meals more fully and prevent overindulgence.

Healthy Alternatives

• Seek out healthier alternatives to satisfy your cravings. For example, if you’re craving something sweet, opt for fresh fruit or a small piece of dark chocolate. If you’re craving something savory, try air-popped popcorn instead of chips.

Seek Support

• If you find it challenging to control your cravings, consider seeking support from a registered dietitian, therapist, or support group. They can provide strategies and encouragement tailored to your specific needs.

Remember, you’re not alone in facing these cravings, and it’s entirely possible to make healthier choices without depriving yourself completely. By incorporating these tips and staying mindful of your eating habits, you can combat the effects of the brain’s love for fats and sugars while still enjoying the pleasures of good food. It’s all about finding that tasty balance!

Netflix’s “You Are What You Eat: A Twin Experiment,” directed by the acclaimed Louie Psihoyos, presents a look at the effects of diet on health through the unique lens of an 8-week ‘controlled’ study by Stanford University. The documentary series, released in January 2024, unfolds the intriguing findings from an experiment involving 22 sets of genetically identical twins.

The overarching message of the series is that ‘meat is bad for you, and plants are good for you’, as is seemingly made evident by Dr. Christopher D. Gardner, Ph.D., the study’s author and principal investigator. However, a closer examination of the study uncovers limitations and concerns.

The study’s premise was straightforward: each twin was assigned a different diet—one vegan, one omnivore—both seemingly balanced and nutritious. Initially, the twins received pre-prepared meals to ensure dietary adherence, followed by a transition to self-prepared meals for practical application. Commentators then chime in to provide additional insights based on their expertise, including NYC Mayor Eric Adams, Senator Cory Booker, Dr. Michael Greger, and Marion Nestle.

Considering Overall Health

We agree that a diet rich in fresh produce and limited in red meat is certainly the way to go!

But before you jump into all vegan diet, consider some of the drawbacks and how to manage them.  This film entices you to become a vegan because the twin that eliminated meat showed significant outcomes: a 10% to 15% decrease in LDL cholesterol, a 25% reduction in insulin levels, and a 3% weight loss—all achieved through whole, plant-based foods without any animal products. Conversely, those on the omnivore diet showed no significant health benefits.

While the vegan group experienced positive changes in their LDL cholesterol (the bad one) and weight loss, they also had negative changes in HDL cholesterol (the good one) and triglycerides (bad fat).  High triglycerides may contribute to the hardening of the arteries or thickening of the artery wall, therefore, contributing to heart disease.

Furthermore, the oversight of potential risks associated with Vitamin B12 deficiency in the documentary is a significant concern. Vegetarians need to take a B12 supplement to make sure they have enough of this crucial nutrient for their overall health, particularly for the proper functioning of our nervous system and the production of red blood cells.

Additionally, the documentary‘s observation that the weight loss in the vegan group primarily consisted of muscle loss raises concerns about the impact of unbalanced weight loss strategies.

Losing muscle mass during weight loss is generally undesirable because muscle tissue plays a crucial role in metabolism, physical strength, and overall well-being.

Muscles help burn calories and support daily activities, and their loss can lead to a decrease in metabolic rate, making it harder to maintain a healthy weight.

Another noteworthy concern is its feasibility as a long-term diet. Most participants in this study reported lower dietary satisfaction with a vegan diet suggests that long-term adherence to such a diet may be challenging for many individuals. This aspect challenges the feasibility and practicality of adopting a vegan lifestyle for a substantial portion of the population.

If you’re interested in adopting a better way of eating that eschews the potential bias, the study’s limitations, potential deficiency risks, and the challenges associated with long-term dietary adherence, consider The Mediterranean Diet. This tried and true eating style has the most peer-reviewed research showing its positive effects towards living a long and healthful life.

And should you want your diet to factor in particular health concerns, consider researching epigenetics. This is the study of how your behaviors and your environment can cause changes in how your body reads your DNA.

Ideological Issues

There are plenty of healthy vegans, so that is not the issue.  It seems as though those affiliated with the documentary is using diet to make a political stance on meat.

This becomes evident when we consider the affiliations of Dr. Gardner one of the study authors, who is connected to Beyond Meat, a prominent producer of plant-based meat alternatives. While financial conflicts of interest were disclosed in the study, there is also a strong conviction in promoting a plant-based diet.

The film also focuses on animal welfare concerns associated with meat production but fails to address issues related to growing our food.  Every single bite we take has its own, including labor issues, pesticide concerns, and water usage, to name a few.

By solely emphasizing animal rights, the documentary neglects broader ethical and environmental considerations in our food system that span to crops and plant-based diet foodstuffs as well.  This documentary falls into the same category as so many others.

Not The First…and Certainly Not The Last

Consumers are often drawn to exciting and visually compelling documentaries about food, especially when they promise groundbreaking revelations about nutrition and health.

These documentaries can be engaging, emotionally charged, and persuasive, making them highly effective in shaping public opinion. However, it’s important for consumers to recognize that these films are often crafted with a specific agenda or perspective in mind and overlook some core components.

While documentaries can provide valuable insights into various aspects of our food system, they should not be the sole source of information when it comes to making important dietary decisions. Here’s why consumers should exercise caution and seek factual resources for nutrition information:

To make informed decisions about nutrition, consumers should seek out a variety of reputable, evidence-based resources. These can include peer-reviewed scientific journals, registered dietitians or nutritionists, government health agencies, and academic institutions specializing in nutrition and health research.

By consulting a range of sources and critically evaluating information, consumers can make dietary choices that are based on a well-rounded understanding of nutrition rather than being swayed solely by the excitement of a compelling documentary.

A case study in how much protein is enough

Take, for instance, Patrick and Cynthia. Patrick’s day consisted of sitting at his desk at work, working on his computer, and then coming home to relax on his couch with some TV shows. He rarely engages in any physical activity or exercise except for an after-dinner stroll with his wife.

Patrick’s protein needs are usually calculated based on his body weight, which is 195 pounds. His recommended daily protein intake is  0.35g per pound of body weight, which amounts to approximately 70g of protein per day. This amount of protein is enough to meet Patrick’s minimum physiological protein needs and support his lifestyle.

On the other side of the spectrum is an athletic individual named Cynthia. Cynthia is gearing up for a marathon while weightlifting and doing high-intensity intervals as part of her training.

How much protein does Cynthia need each day? Based on her body weight of 154 pounds and intense level of activity, her recommended daily protein intake is about o.73g per lb., which amounts to approximately 112g of protein per day. This is necessary because her body needs more protein to repair and build muscle tissue, support her high-intensity workouts, and recover faster.

Body weight & lifestyle factors

Most of us fall in between Cynthia and Patrick. We exercise between 30-60 minutes a day, and it can range from yoga and walking to lifting weights and high-intensity cardio. Our protein intake depends on our lifestyle and energy needs.

The American College of Sports Medicine indicates that anywhere from 10-35% of the average American’s diet should contain proteins. In terms of bodyweight, this means a recreational athlete weighing 150 pounds should strive for between 75-90 grams per day.

Of course, if you exercise more, you can increase your protein consumption— but you don’t need to overdo it! If you are eating protein with the hopes of building muscle, the quality, quantity, and timing of consumption is more important than the overall amount you eat.

Which protein sources are best?

When eating protein, you want to make sure it is a complete protein, meaning it contains all 9 essential amino acids. Eggs, milk, and lean beef are high-quality proteins that are easily digestible. For instance, one large egg contains around 6 grams of protein.

Turkey, chicken, and fish are also a good source of protein. 3 oz. of chicken or fish contains anywhere from 19-24 grams of protein.

Dairy is another great source of protein: a 5.3 oz container of plain Greek yogurt contains 15 grams of protein. A cup of milk has roughly 8 grams of protein and an ounce of cheese contains 7 grams of protein.

Legumes have protein, too! A cup of lentils contains roughly 16 grams of protein. Including a variety of vegetable protein sources in your diet is also a good strategy to ensure you’re getting a range of nutrients.

But let’s say you are the average athlete, and you weigh 150 pounds and need about 75-90 grams of protein. In one day, if you ate:

• 1 cup of oatmeal (10g of protein)
• two eggs (12 g)
• 6 oz of chicken (42g)
• ½ cup of lentils (8g)
• 1 cup of black beans (15g)

…you would have consumed 87 grams of protein.

But honestly, that is a lot of food. Plus, you need to add in more fruits and vegetables and some carbs. So, it is tempting to throw in some protein powder on your oatmeal in the morning or eat a protein bar as an afternoon snack.

What about protein supplements?

Are protein products, like shakes, powders, and bars, part of your daily routine? The protein supplement market has been rapidly expanding, with the industry fueled by factors such as the aging population, fitness trends, growing interests in plant-based protein supplements, and accessibility to e-commerce. There is also a continuous interest in self-care, contributing to the growth of this industry.

The question of whether protein supplements are good for you depends on various factors, including your dietary needs, health status, and lifestyle. Of course, like any change in your diet, it is best to ask your doctor.

However, EatingWell suggests that high-quality, third-party tested protein powders with minimal sugar and no harmful additives can be a healthy choice. As we age, we lose muscle, and boosting our protein intake may help increase strength and lean body mass, especially if you have a restricted diet.

Medical News Today also shares research suggesting that protein supplements significantly improve muscle size and strength in healthy adults who perform resistance-based exercise training.

Protein powder considerations

However, it’s important to consider the quality control of protein supplements. As per a review published on Human Kinetics, safety assessments are crucial, especially given the potential addition of cheaper ingredients to increase total protein content.

According to Harvard Health, protein powder supplements can harbor health risks and are recommended only for certain conditions, such as impaired appetite or wounds. You should make sure that the protein powder is ‘clean’ and does not have unnecessary additives. NIH published a study indicating that some protein powder supplements can have heavy metals.

Lastly, online sales of protein supplements have increased, indicating a shift in how consumers purchase these products. However, this also highlights the need for further education on potential health risks from unregulated protein supplements, as stated in a study on Wiley Online Library.

Can you consume too much protein?

You might not need your morning protein shake as much as you think. Of course, like anything else, too much of a good thing is just…too much.

Cleveland Clinic stresses that aside from bad breath, too much protein can overstress your kidneys causing kidney damage, digestive problems, and dehydration. It is always important to drink enough water to make sure your kidneys function well.

Protein supplements can certainly be a healthy addition to your diet, but they’re not for everyone. These supplements are often utilized by athletes and those with specific dietary requirements who may struggle to meet their protein needs through food alone.

So, while protein supplements can be beneficial for some, they should be used wisely and under the guidance of a healthcare or nutritional professional.
