Complicated issue: Intact skin repels things that get on the skin, low pH from fatty acids is inimical to bugs of all kinds, epithelial cells do not have the receptors that HIV needs to bind to, to get into cells, and more. You may consult this site for technical information. http://www.ncbi.nlm.nih.gov/pubmed/19043850 For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
