Diet, nutritional status, and lifestyle are modifiable risk factors for COVID-19 and its comorbidities. These factors should be highlighted in public messaging about the COVID-19 pandemic.

Biomarker clues can provide insight into the severity of COVID-19 as well as underlying nutrient insufficiencies and deficiencies.

It is imperative that assessment of key biomarkers and nutrients be part of COVID-19 evaluation, monitoring, and therapy, especially:

  • Inflammatory markers
  • Transaminase enzymes
  • LDH
  • Fibrinogen
  • WBC differential
  • Neutrophil:lymphocyte ratio
  • IL-6, IL-10
  • Albumin, prealbumin
  • Vitamin C
  • Vitamin D
  • Selenium
  • Zinc

Remember that optimal lab ranges are narrower than standard lab ranges and may give earlier clues to imbalance or deficiency.

A healthy dietary pattern modeled on the Mediterranean diet or DASH diet can help reduce the risk of chronic metabolic diseases and in turn, reduce the risk of severe COVID-19:

  • Minimum of 4 servings of fruit, 5 servings of vegetables during COVID and beyond
  • Adequate whole grains, meats, beans, dairy, protein, whey protein
  • Incorporate herbs, spices, tea, coffee daily
  • Minimum of 35 grams of fiber daily, ideally from whole foods, can supplement with psyllium
  • Include fermented foods, probiotic-containing foods
  • Adequate micronutrient intake particularly vitamins A, Bs, C, D, E, zinc, and selenium
  • Minimize or eliminate highly processed foods, added sugars and salt, excessive saturated fats, fatty processed meats
  • Targeted nutrition support should be utilized
    • A high-potency multivitamin-mineral supplement can provide a foundation with additional micronutrient supplementation as needed
  • Other factors should be considered in the fight to prevent and treat COVID-19 including
    • Sleep hygiene
    • Stress management
    • Mental health
    • Social connections
    • Environmental factors, clean air, clean water, clean food
    • Health literacy

A Traditional, Complementary and Integrative Health and Medicine Support Registry has been developed to collect longitudinal data “aiming to capture key case, treatment/supportive care, and outcome variables related to the use of traditional, complementary, and integrative health and medicine products and practices in response to the COVID-19 crisis.”[1]

Several organizations from a variety of disciplines have joined the registry and provided an integrated path for improving COVID-19 treatment and resolution.

Finally, be aware that a variety of adverse outcomes can persist even after perceived recovery from COVID-19 and can include:

  • Adverse cardiovascular outcome’s[2] [3] [4] [5]
  • Adverse psychological outcomes[6] [7] [8]
  • Adverse neurological complications[9] [10] [11] [12] [13]
  • Adverse gastrointestinal complications[14] [15] [16]
  • Adverse cutaneous complications[17]
  • Adverse effects on food supply and food security[18] [19]
