Eating less meat is a big part of it. Go meatless one or two days a week. Eat less red meat. Mix in stuff like sardines now and then. It's funny, but some of these old diets that are now touted as healthy were sort of survival diets. That is what they ate because that is what they had. Once western civilization became prosperous, the meat content of the diet jumped up. This is especially true in the U.S.
