Now, in many areas, people are encouraged to eat some vegetables, such as onions and others, on the pretext of strengthening the human immune system in confronting the pandemic of the Covid 19 virus.
But the question remains whether eating vegetables rich in antioxidants and carotenoids has an effective role in strengthening the immune system or reducing the effects of infection with Covid 19 virus.
Dear Dr. Abdelkhalik!
You raised an essential point to think about! Each of us needs to think how to adapt his or her lifestyle to the presence of COVID-19:

Eating vegetables still might not help if one is over-stressed and does not do exercises every day to stay in condition (fit). Since this virus is mysterious and unpredictable I hope the best while preparing for the worst, Yours sincerely, Bulcsu Szekely
POSITIVE ASPECTS OF COVID-19 PANDEMIC:
1. Clean environment and reduction of pollution: By not using bio-fuel (Petrol, gas, wood, coal) due to lockdowns, world has learnt about how we can improve the environmental pollution by green technology
2. Nature is giving the lesson: Survival for the fittest, false claims of increasing survival with vulnerable old populations has been exposed.
3. Justice:What United Nations could not do, Coronavirus is doing. It has affected poor as well as the the wealthy alike. It has made the powerful nations more helpless than weak nations and countries.
Vegetables are a source of macro- and micronutrients required for general health. They improve the immunity as any source of macro- and micronutrients would.
Some people prepare to drink tea, coffee, garlic, onion to protect themselves against the crona virus. I hope for all people to get free against this virus.
The food, animal or vegetable, has the purpose of keeping us in an orderly state (with low entropy) where all the biomolecules necessary for correct functionality are represented, qualitatively and quantitatively. Their influence is not only mechanistic but also deeply functional. Let me explain, the genome does not change structurally, but it can be functionally modified through nutrition (and generally by lifestyle) through superficial changes (e.g. methylations) that we refer to as epigenetic. It is known that certain organic compounds present in foods can induce the expression of genes involved into specific functional problems. This also means that with proper and appropriate nutrition we can have certain physiological functions, such as for example the immune defenses, calibrated to the best of their functionality but always depending on the individual phenotype, which in turn depends on the lifestyle, on the age, gender, etc. Therefore proper nutrition, even with supplements, allows us to oppose the infection but always within the maximum potential dictated by the specific individual phenotype.
Fresh vegetables and fruits are very good source of antioxidants, fibreand phytochemical and natural anti biotics which are antimicrobials.
Mineral nutrients present in vegetables surely provide immunity against the covid-19.
Nutrients do not ensure immunity against SARS-CoV-2, but improve the functionality of the immune system depending on the individual phenotype and against all infections. This does not mean that "surely provide immunity against the covid-19". Words have a weight that can be misunderstood by those unfamiliar with scientific facts.
Doctors believe that Keeping warm interior body helps you much, so tea, coffee drinking works well.
Vegetables helps in body metabolic processes, therefore it can boost body immunity. It is advisable to include enough vegetable as a food component in our diet.
Dear Ahmad.
A virus is a molecular machine that moves only chemically. It has an impressive ability to thread into the gray areas of our immune defenses to use them to its advantage, deactivating them. It does this only with chemical reactions.
If so, chemistry teaches that the biochemical kinetics of enzymes, of interactions between molecules, and so on, increases by enhancing the temperature. So keeping the body warm favors the viral action many times over.
Here we do not have to favor chemical reactions that increase sputum to improve our cold, here we are in the presence of a molecular killer who knows us deeply. Better not to favor it.
