It is very dangerous to start thinking that a good diet will prevent HIV infection (and subsequently AIDS). The methods of HIV trsnsmission have been determined: exchange of body fluids (semen, blood), transfusion of contaminated blood, use of contaminated needles. There may be a corelation between a lower infection rate amongst people who eat well, but I would think that comes from a better life style occasioned by a better income occasioned by a better education. The key then would be education, not food. Thinking that AIDS can be prevented by a good diet is very foolish, and the promulgation of that type of thought is criminal. And if it isn't, it should be.
