Your diet is your first medication. If the food we eat doesn't kill bacteria or viruses,
some of them boost our immune system. There is currently no vaccine or treatment for
Covid-19, so there is no shortage of ways to boost your immune system.
Numerous studies have proven that even a slight deficiency of zinc weakens immune function. Certain reflexes
can help to reinforce immunity during this epidemic period, even if the most effective remains to respect the barrier gestures and containment measures put in place.
1. What are the allied elements of immunity?
It is one of the most promising preventive remedies against Covid-19 and its complications.
At the immune level, it has an important role in activating and developing certain white
blood cells, the T-lymphocytes. These are necessary to destroy microbes. While vitamin D
has no proven usefulness against Covid-19 itself, it helps fight certain bacteria and possibly
It can also help regulate inflammatory and immune responses when they get out of
control. It is mainly present in fatty fish: cod liver and its oil, smoked herring, raw natural
bacon, mackerel, grilled sardines, raw anchovies, steamed salmon, poached egg. A
minimum recommended intake is 5 micrograms per day.
Antioxidant, it protects white blood cells from oxidation and increases their mobility. It also stimulates the production of cytokines, molecules produced by the cells of the immune system to destroy microbes. An American doctor reports that a 71-year-old Chinese patient has survived Covid-19 because of vitamin C intake. Since the beginning of the epidemic, a major hospital in Shanghai and hospitals in New York have been injecting large doses of
vitamin C into hospital patients, with promising results.
An American doctor using vitamin C in intensive care at his hospital in New York said, “Patients who receive vitamin C do much better than those who do not.” We find Vitamin C in fruits and vegetables such as fresh blackcurrant, fresh parsley, raw red pepper, lemon, zest, raw green pepper, fresh red fruit, kiwi fruit, raw cauliflower, raw red cabbage, squeezed orange. Its recommended daily dose is 110 mg.
A trace element that helps us resist infections. This element is essential for immune cells to produce antimicrobial molecules. It protects cell membranes from free radicals and infections by microbial agents. The foods richest in zinc are raw hollow oyster, cooked calf liver, braised beef, rye and wheat bread, salt-free rusk, unsweetened cocoa, minced steak. Our daily requirements are 10 to 15 mg.
2. What are the foods to avoid?
Onions, shallots, vinegar, red meat.
Cow’s milk, yogurt, cheese. This does not mean that we will run out of calcium if we eat less, or even more at all because we have more than enough calcium in the rest of our diet.
Also to be avoided:
Industrial wheat flour, sugar, especially hidden sugars in industrial products. Excess garlic, black and green teas, coffee, beer, and farmed fish should also be avoided. These pro-inflammatory foods may promote abnormal immune system responses, which can be harmful if you have Covid-19.
