At this point in human evolution, a certain gene, known as CMAH, that allows for the synthesis of a sugar called Neu5Gc, went missing. This sugar is present in red meats, some fish and dairy products. When humans consume an animal that has that gene, the body has an immune reaction to the foreign sugar, which can cause inflammation, arthritis, and cancer. items to wear for girls of the wedding
