I am unaware of a dietary link with boils. Most boils are localized staph or step infections, bacteria that is on everybody’s skin. Some people have more fragile skin than others, and are more prone to tiny microscopic tears that get infected and make boils. I do suggest that people prone to them check their diet for omega3 and onega6 fats, needed for healthy cell membranes and only available through diet or supplement… our bodies can’t make them like they can other fatty acids. But boils aren’t caused by a poor diet.
Also to tie this to the body wash thread, the skin’s natural acid mantle provides a slightly acidic barrier to bacterial infection that most soaps (being alkaline) tend to reduce or destroy, leaving the skin more prone to infection.
Holy shit. I mean, that really looked like shit to the extent I thought he’d perforated the bowel
