How To Keep Mitochondria "Merry and Bright" Through The Holidays

Keeping Mitochondria Operating Properly Through The Holidays

Tis the season to overindulge. Between holiday parties, traditional favorite dishes, and gifts of cookies, cakes, candies, etc., set out everywhere for sharing, it is difficult to avoid excess calories, and for those who drink, alcohol may also be enjoyed to excess (or beyond!).

Mitochondria produce the ATP energy our bodies require. So, what does holiday indulgence have to do with mitochondria? Both overnutrition and excess alcohol use can exacerbate existing mitochondrial dysfunction and inflammation. Without good mitochondrial function, patients may be more inflamed, fatigued, or depressed. Mitochondrial function is also essential for proper immune system responses – dysfunctional mitochondria may not respond appropriately when patients are exposed to pathogens such as cold, flu, Coronavirus, or respiratory syncytial virus (RSV).

Alcohol detoxification occurs via cytochrome P450 enzymes found within mitochondria such as CYP1A1, 2B1, 2E1, etc. These same enzymes are important not only for alcohol and chemical detoxification but for hormone and lipid metabolism. All cytochrome P450 enzymes need a heme-iron molecule in their structure, and all require NAD(H) as a cofactor to function. Alcohol dehydrogenase, the other primary alcohol detoxification enzyme also requires NAD(H), and needs zinc incorporated into its structure. The cofactor NAD(H) is derived from vitamin B3, so individuals low in B-vitamins or minerals may have problems with alcohol detoxification or other metabolic functions.

A functional assessment of mitochondrial function is available using US BioTek’s dried urine Organic Acids profile:

The pattern of analytes can provide a great deal of information regarding mineral and specific B-vitamin needs. It is easy to see in the image just how important B3 (as NAD(H) or NADP) is to mitochondrial function – almost every step in the mitochondrial citric acid cycle requires B3!

Alcohol is not the only indulgence that can disrupt mitochondrial function, however. Overnutrition (the chronic consumption of excess calories) increases chronic inflammation and the risk of type II diabetes. Overnutrition also dysregulates mitochondrial function. The dysregulation may be worse in patients who cannot properly assimilate macronutrients such as carbohydrates, fats, and proteins. 

Diet and Metabolic Pathways

In addition to nutritional mitochondrial supports, patients may be educated to avoid over-indulgence in the first place. The Mayo Clinic offers the following advice to support healthy celebrations:

  • Don’t skip meals to “avoid” calories.
  • Fill half of any plate with festive fruits and vegetables.
  • Eat slowly and savor the food on the plate.
  • Wait before going back for “seconds.”
  • Appreciate special treats – select 1-2 favorite seasonal foods and leave the rest
  • Stick with low or no-calorie alcohol-free beverages
  • Good self-talk: “I can make this food again if I want to,” “The leftovers will be delicious, too – let’s save some for another meal,” “I choose to enjoy this meal and these seasonal treats,” etc.

‘Tis the season for celebration, not overindulgence. Keep your patient’s mitochondria merry and bright this season so all can enjoy a happy, healthy holiday season.
