Something to consider. Since cell membranes consist of mostly lipids/fatty components and viruses have to traverse this membrane to get into cells dietary fats consumed may have an effect on immunity. Any google search of fatty diet and immune system will return numerous articles. It is put nicely here:
"The development and optimal functioning of our immune system is directly influenced by our diet. Any deficiency or excess of certain nutrients can affect the number and activity of immune cells. Among the nutrients identified, dietary fatty acids are described as having major effects on immunity. Indeed, the fatty acid composition of the membranes of immune cells seems to be easily modulated under the effect of dietary fats and the resulting rapid changes in composition are likely to generate functional effects on the reactivity and functioning of these cells within a very short period of time."
There may be a reason why covid19 is heavily co-morbid in overweight poor diet people.
Apparently Sugar puts the immune system in temporary Coma.
