The animals that provided meat to Paleolithic peoples ate grass and leaves, which are rich sources of alpha-linolenic acid. For this reason, game meat contains large amounts of anti-inflammatory omega-3 fatty acids. Today, when farm animals are fed corn and other grains, their mus cles contain almost no omega-3 fatty acids and substantial amounts of saturated fats.
It is important to avoid, or strictly limit your intake of, meat from corn-fed animals. This caution often applies to meat or eggs from "vegetarian-fed" animals, which may be corn-fed. Many natural foods stores, such as the Wild Oats and Whole Foods chains, have full-service meat departments, and many of their meats are from grass-fed or freerange animals. Similarly, chicken, turkey, and duck should come from animals that were allowed to peck around for their natural diet, not fed corn and other grains. Always ask your butcher to be sure. See appendix B for sources of meat from grass-fed animals.
