BTW, heme iron seems to be a two-edged sword:
Like some philosopher once said, moderation in all things is a virtue.The higher colon cancer risk from red meat may be due to its levels of the heme form of iron. Heme iron is only found in animal foods, and the amount in beef is about twice that in chicken and fish. It has a different chemical form than the iron in plant foods and supplements. Heme iron seems to damage the lining of the colon and cause abnormal cell growth. One study shows that increasing red meat leads to more NOCs in the colon. Red meat’s heme iron produces more NOCs than iron from plant foods.
