There is no any scientifically proven functional food which can prevent or cure SARS-CoV-2 infection.
The target should be to enhance immunity and will prevent the infection or the rate of mortality.
For now, there is no scientifically proven functional foods that can prevent COVID-19
No any scientifically proved food however, as per UNICEF, WFP , WHO, and FAO follow healthy diet includes, variety of food from all food group, consume fresh fruits and vegetables with good hydration and limitation of salt and sugar in diet will be helpful in recovery .

However, I advise on the consumption of fresh fruits, vegetables, nuts, fermented dairy products, pulses etc. to boost the immunity. A person with strong immunity can hardly get infection.
