Bacteria in intestines reacts to red meat causing heart disease.
Very interesting article. Apparently the real culprit in heart disease was not fat, they proposed instead that it was a little-studied chemical that is burped out by bacteria in the intestines after people eat red meat. It is quickly converted by the liver into yet another little-studied chemical called TMAO that gets into the blood and increases the risk of heart disease. A little disconcerting if true.
