How to lower your risk of COVID-19?
https://theconversation.com/5-ways-nutrition-could-help-your-immune-system-fight-off-the-coronavirus-133356"The coronavirus presents many uncertainties, and none of us can completely eliminate our risk of getting COVID-19. But one thing we can do is eat as healthily as possible.
If we do catch COVID-19, our immune system is responsible for fighting it. Research shows improving nutrition helps support optimal immune function.
Micronutrients essential to fight infection include vitamins A, B, C, D, and E, and the minerals iron, selenium, and zinc.
Vitamin D

Excerpt from abstract: "Results: The mean level of vitamin D (average 56mmol/L, STDEV 10.61) in each country was strongly associated with the number of cases/1M (mean 295.95, STDEV 298.73 p=0.004, respectively with the mortality/1M (mean 5.96, STDEV 15.13, p < 0.00001).
Discussion: Vitamin D levels are severely low in the aging population especially in Spain, Italy and Switzerland. This is also the most vulnerable group of population for COVID-19.
Vitamin A
Vitamin A maintains the structure of the cells in the skin, respiratory tract and gut. This forms a barrier and is your body’s first line of defence. If fighting infection was like a football game, vitamin A would be your forward line.
We also need vitamin A to help make antibodies which neutralise the pathogens that cause infection. This is like assigning more of your team to target an opposition player who has the ball, to prevent them scoring.

Vitamin A is found in oily fish, egg yolks, cheese, tofu, nuts, seeds, whole grains and legumes.
Further, vegetables contain beta-carotene, which your body can convert into vitamin A. Beta-carotene is found in leafy green vegetables and yellow and orange vegetables like pumpkin and carrots."

B vitamins
They do this by influencing the production and activity of “natural killer” cells. Natural killer cells work by causing infected cells to “implode”, a process called apoptosis."
Vitamins C and E
"When your body is fighting an infection, it experiences what’s called oxidative stress. Oxidative stress leads to the production of free radicals which can pierce cell walls, causing the contents to leak into tissues and exacerbating inflammation.
Vitamin C also helps clean up this cellular mess by producing specialised cells to mount an immune response, including neutrophils, lymphocytes and phagocytes.
So the role of vitamin C here is a bit like cleaning up the football ground after the game.
Good sources of vitamin C include oranges, lemons, limes, berries, kiwifruit, broccoli, tomatoes and capsicum.
Vitamin E is found in nuts, green leafy vegetables and vegetables oils."
Iron, zinc, selenium, green tea, black tea
"We need iron, zinc and selenium for immune cell growth, among other functions.
Iron helps kill pathogens by increasing the number of free radicals that can destroy them. It also regulates enzyme reactions essential for immune cells to recognise and target pathogens.
Zinc helps maintain the integrity of the skin and mucous membranes. Zinc and selenium also act as an antioxidant, helping mop up some of the damage caused by oxidative stress.
Iron is found in meat, chicken and fish. Vegetarian sources include legumes, whole grains and iron-fortified breakfast cereals.
Zinc is found in oysters and other seafood, meat, chicken, dried beans and nuts.
Nuts (especially Brazil nuts), meat, cereals and mushrooms are good food sources of selenium."
METHYL
"Epigenetic Modulation of Host Response: Like other ssRNA viruses, when SARS-Cov-2 infects host cells, the virus requires continuous cellular transcription for viral mRNA synthesis. This mechanism implies functional association with the host’s genome expression so that it adapts the infected cell for the host-to-pathogen confrontation at each replication.[6] A key role is that RNA viruses can recruit host DNA methytransferases (DNMTs) to methylate and decrease gene function of specific genes including those for shaping innate and adaptive immune responses."
So, please take care of proper methylation.
