What You Need to Know: Reduce Your Risk of COVID and Co-Morbidities

Beth Ellen DiLuglio, MS, RDN, LDN

COVID-19 is a highly contagious viral infection that may be asymptomatic or may present with severe or even fatal sequelae. Severity of the disease appears to be associated with fixed risk factors such as advanced age, immunosuppression, malignancy, darker skin, and end-stage diseases including lung, liver, and kidney disease. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]

It is also associated with conditions and modifiable risk factors that may become chronic but can be addressed with lifestyle changes and nutrition intervention.[12]

Modifiable risk factors for severe COVID-19 include

  • Blood glucose dysregulation
  • Cardiovascular disease
  • Diabetes, type 2
  • Excess alcohol intake
  • Exposure to pollution and toxins
  • Hypertension
  • Inflammation
  • Lack of sunlight exposure
  • Nutrient insufficiencies
  • Obesity
  • Oxidative stress
  • Sedentary lifestyle
  • Smoking
  • Unhealthy Western-style diet

Avoid an unhealthy dietary pattern containing an excess of: [13] [14]

  • Animal fat
  • Commercial snack & convenience foods
  • Concentrated sweets
  • Diet soft drinks
  • Fast foods
  • Fried foods
  • Highly processed foods
  • Processed meats
  • Red meat
  • Refined grains
  • Sodium, added salt
  • Sugar, sugar-sweetened beverages
  • Trans-fats
  • And LACK of fresh fruits, vegetables, whole unprocessed foods

Adopt a healthy dietary pattern with an abundance of: [15] [16] [17] [18] [19] [20] [21]

  • Dairy, low-fat, fermented
  • Healthy fats, omega-3s
  • Herbs, spices
  • Purified water
  • Fruits, 4 servings per day (fresh, include citrus, berries, etc.)
  • Lean protein
  • Legumes, beans
  • Nuts, seeds
  • Plant-based foods
  • Seafood, fish
  • Vegetables, 5 servings per day (fresh, include leafy greens, cruciferous, etc.)
  • Whole, unprocessed foods
  • Whole grains
  • Vitamins: A, Bs, C, D, E
  • Minerals: copper, iron, magnesium, selenium, zinc
  • Phytonutrients: flavonoids, polyphenols
  • Tea, coffee

Lifestyle factors that promote optimal health and help reduce the risk of infectious disease and comorbidities include:

  • An active lifestyle with regular exercise
  • Goals and achievements
  • Health awareness and literacy
  • Mental health checkups
  • Recreation and “down time”
  • Restful sleep 7-9 hours per night
  • Self-care
  • Social connections and interactions
  • Stress management

The bottom line of what you need to know about reducing the risk of COVID-19 and its comorbidities is:

  • Adopt a healthy plant-based diet abundant in micronutrients, phytonutrients, antioxidants, fiber, and purified water.
  • Avoid or minimize highly processed and fast foods.
  • Incorporate regular physical activity and structured exercise into your day.
  • Manage stress… anticipate its arrival and plan for its departure.
  • Sleep well for as long as you need to, most need 7-9 hours.
  • Plan achievable, fulfilling goals.
  • Social interactions are important too!
