The Paleo craze has taken over the world. It asks curious dieters to look back to their ancestors' eating habits to discover a "new" way to eat that shuns grains, most dairy, and processed foods. But, while diet books with Paleo in the title sell well--are they correct? Were paleolithic and ancestral diets really grain-free, low-carb, and based on all lean meat?

In Nourishing Diets bestselling author Sally Fallon Morell explores the diets of our primitive ancestors from around the world--from Australian Aborigines and pre-industrialized Europeans to the inhabitants of "Blue Zones" where a high percentage of the populations live to 100 years or more. In looking to the recipes and foods of the past, Fallon Morell points readers to what they should actually be eating--the key principles of traditional diets from across cultures -- and offers recipes to help translate these ideas to the modern home cook.
