• Go plant based. A diet high in animal protein, creates an ideal environment for viral replication. The best way to create an unfavorable environment in your body for viral replication is by eating a Whole Food Plant Based Diet. The standard American and the Keto Diet is high in animal protein and dairy, creating favorable conditions for viral replication and immune suppression. A Whole Food Plant Based diet is alkaline in nature, which strengthens immunity and assists in faster recovery from illness.
  • Keep your liver healthy. If your liver is compromised due to alcohol and/or animal protein consumption or fatty liver, it will be slow to assist the immune system in reducing viral load early during an infection. Avoiding alcohol and eating green leafy vegetables, cleanses the liver and optimizes its function. This also boosts the immune response and increases the production of anti-oxidants. The liver is highly regenerative so once you begin making these lifestyle changes, it responds rapidly, within one to two weeks, resurrecting and boosting immune function and antioxidant production.
  • Move your body. Aerobic exercise is an important choice that stimulates the liver and supports the immune system to optimize detoxification and antioxidant production. 20 to 40 minutes of aerobic exercise per day is adequate for this effect. (Please clear this with your physician before staring any exercise program).
  • Reduce inflammation. This is best accomplished with a Whole Food Plant Based Diet. If your body is not inflamed, the damage to your tissues from an amplified inflammatory response from any viral attack can be reduced. In addition, cooking with spices like turmeric also stimulates natural-killer cell activity, the first responders after viral entry. Turmeric needs to be heat activated so taking it in supplement form is ineffective. (Curcimin, the the active ingredient in turmeric carries antioxidant effects). Adding dark anti-oxidant rich foods and spices such as cardamom and cloves , can also enhance natural-killer cell function resulting in a reduced viral load.
  • Get your sleep. Seven to eight hours of sleep per night is necessary to enhance cellular regeneration and reduce inflammation. Deep sleep relaxes the body and neutralizes stress hormones which are inflammatory and immunosuppressive.
  • Take your supplements. Supplements to boost and support your immunity may be helpful. There have been no studies thus far on the beneficial effects of supplements for preventing COVID-19 so supplements are not substitutes for evidence based preventive measures.
  1. Zinc, 20 mg per day has been shown to reduce viral replication in in vitro studies.
  2. Vitamin C 2000 mg per day (if you have kidney stones, check with your doctor before taking this) is a potent anti-oxidant which assists the body in anti-viral activity.
  3. Vitamin D3 2000 to 5000 IU per day has been shown to assist in immune support. Be sure and check your blood levels before taking more than 2000 IU per day to prevent toxicity. Vitamin D is a fat soluble vitamin and can be toxic if taken unmonitored in high doses).
  4. A broad spectrum probiotic is key in keeping the gut microbiome and immune system healthy. An effective probiotic should have at least 5 strains of Lactobacillus and up to 5 strains of Bifidum to populate the intestines and provide bio-diversity. To ensure that your probiotic is temperature stable, it is better to get one that does not need refrigeration. The gut microbiome is essential for a healthy nervous system and immune system.
