Eating for Healthy Mitochondria

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!

You have over 100,000 trillion mitochondria within your body right now that seamlessly work to create energy to keep your body functioning.

That amounts to a staggering 1,000 to 2,500 mitochondria in each of your cells, chugging away to keep all of your organs working as they should.

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.

While diet alone cannot change illnesses from genetics or excessive toxic exposure, it can fortify your mitochondrial function and serve as a supplemental treatment for these diseases.

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.

How bad is alcohol for us?

Sitting down for cocktails and dinner with friends and family is so enjoyable on a Friday or Saturday evening after a long week. But after tuning into an episode of Dr. Huberman’s podcast on drinking’s effects on our health, we took a closer look into how our body processes alcohol.

As it turns out, Dr. Huberman was onto something. New research has shown that the nice little drink in your hand can have more detrimental effects on our brain and body than we originally knew. In fact, emerging studies reveal that even low levels of alcohol consumption can have significant negative impacts on health.

So we gathered information from recent studies to answer some important questions:

Maybe those weekend cocktails are not such a good idea after all…

Alcohol metabolism, toxicity & cancer risk

When ingested, alcohol – also known as ethanol – is metabolized by the liver. This process involves converting ethanol to acetaldehyde, a toxic compound that damages cells and tissues. The liver uses the enzyme alcohol dehydrogenase to break down ethanol into acetaldehyde, which is then converted to acetate.

While acetate can be utilized as an energy source, the intermediate production of acetaldehyde is harmful and contributes to the toxic effects of alcohol​.

The liver, being the primary site of alcohol metabolism, suffers significant damage from prolonged alcohol exposure. Acetaldehyde can induce oxidative stress, leading to liver inflammation, fatty liver disease, and cirrhosis over time​.

But the damage doesn’t stop there. Acetaldehyde can circulate through the bloodstream, impacting various organs and systems. And ethanol and its metabolites can damage DNA and promote carcinogenesis through several mechanisms, including oxidative stress and interference with DNA repair processes.

The effects of metabolizing ethanol also influence hormone levels, increasing estrogen levels, a risk factor for breast cancer. This is why alcohol consumption is associated with an increased risk of various cancers.

Alcohol’s effects on the brain

Alcohol’s influence on the brain is multifaceted, affecting both structure and function:

Neurodegeneration:

Chronic alcohol consumption, even at low to moderate levels (7 to 14 drinks per week), can lead to brain atrophy, particularly thinning of the neocortex and other critical brain regions. In fact, Huberman suggests that anything beyond two drinks a week has negative consequences. This structural degeneration can impair cognitive functions, including memory and executive functions.

Neurotransmitter disruption:

Alcohol acts as a central nervous system depressant, influencing neurotransmitter systems. It increases the activity of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, while simultaneously inhibiting glutamate, an excitatory neurotransmitter. This dual action leads to the characteristic sedative effects of alcohol and impairs cognitive functions and memory formation.

Behavioral changes:

Alcohol reduces the activity of the prefrontal cortex, the brain region responsible for decision-making, impulse control, and social behavior. This suppression can lead to increased impulsivity, risk-taking behaviors, and reduced inhibition, contributing to alcohol-related accidents and injuries.

Mood and mental health:

Alcohol disrupts the balance of serotonin and other neurotransmitters involved in mood regulation. This disruption can exacerbate conditions such as depression and anxiety. Regular alcohol use can lead to a cycle of dependence and withdrawal, further complicating mental health issues.

Impact on the microbiome

Alcohol has a significant impact on the gut microbiome, the community of microorganisms living in our intestines.

Alcohol kills both beneficial and harmful bacteria, leading to dysbiosis (microbial imbalance). This disruption can cause “leaky gut syndrome”, where the intestinal lining becomes permeable, allowing toxins and bacteria to enter the bloodstream. This condition is linked to systemic inflammation and a host of health problems, including liver disease and increased susceptibility to infections.

Maintaining a healthy gut microbiome is crucial for mitigating some of alcohol’s negative effects. Consuming probiotics and fermented foods, such as yogurt and kimchi, can help restore microbial balance and reduce inflammation.

Strategies to mitigate the effects of alcohol

The scientific evidence outlined here underscores alcohol’s potential risks.

From neurodegeneration to mental health issues, leaky gut, and increased cancer risk, its deleterious effects seem frightening, and rightfully so.

But this can feel contradictory to the social norms that encourage moderate alcohol consumption, making it a real challenge to curb this habit. And for those who enjoy the taste, like a fine wine or specialty bourbon, implementing personal behaviors that support this research can feel stifling.

However, we can exercise a few healthy habits that can help our body recover from the effects of long-term alcohol consumption while instilling new, healthier behaviors now.

Hydration is key

Proper hydration and a balanced diet are essential for mitigating the acute effects of alcohol, such as hangovers. Alcohol is a diuretic, causing increased urine production and leading to dehydration. To counter this:

  • Drink plenty of water before, during, and after consuming alcohol
  • Electrolyte solutions can help replenish lost minerals and maintain physiological balance

Dietary choices

Certain foods and supplements can help mitigate alcohol-induced oxidative stress and support liver function:

  • Antioxidants: Foods rich in antioxidants, such as berries, nuts, and dark leafy greens, can help neutralize free radicals produced during alcohol metabolism
  • B vitamins: Alcohol consumption depletes B vitamins, which are essential for energy production and brain health. Supplementing with B vitamins, especially B1 (thiamine), B6, and B12, can help reduce some negative effects
  • Milk thistle: This herbal supplement has been shown to support liver health and protect against alcohol-induced liver damage​

Improve gut health

Maintaining gut health is crucial for mitigating the negative effects of alcohol on the microbiome. Strategies include:

  • Probiotics and fermented foods: Consuming probiotics and fermented foods, such as yogurt, kimchi, sauerkraut, and kefir, can help restore the balance of gut bacteria and reduce inflammation
  • Prebiotics: These are non-digestible fibers that feed beneficial gut bacteria. Foods rich in prebiotics include garlic, onions, bananas, and asparagus
  • Zbiotics is a genetically-engineered probiotic drink that mitigates the effects of alcohol by breaking down the acetaldehyde.

Limit alcohol consumption

Reducing alcohol intake is the most effective way to avoid its negative health impacts. Strategies to limit consumption include:

  • Setting limits: Establish personal drinking limits and stick to them. For example, limit consumption to a certain number of drinks per week
  • Choosing healthy, non-alcoholic alternatives: The popularity of non-alcoholic beverages is growing, offering many options that provide the social experience of drinking without the negative health impacts. Non-alcoholic beers, wines, and mocktails can be enjoyable substitutes
