Our ancestors survived without supermarkets, by growing and preparing their own food. Some of their traditional ways of cooking, that involve fermenting foods like sauerkraut or sourdough bread, are sliding into oblivion. Our guest, Sally Fallon, has been bucking the nutrition establishment to suggest that the old ways of eating have very real and important benefits. She advocates including saturated fats like butter or coconut oil in the diet for good health and she opposes the widespread use of most commercial vegetable oils. Guest: Sally Fallon Morell, founder of the Weston A Price Foundation for Wise Traditions in Food, Farming and the Healing Arts, a nonprofit nutrition education foundation based in Washington, DC. Her book is Nourishing Traditions: The Cookbook that Challenges Politically Correct Nutrition and the Diet Dictocrats. Her Web site is www.WestonAPrice.org. She also founded A Campaign for Real Milk, dedicated to creating consumer awareness of the health benefits of clean, whole unpasteurized milk from grass-fed cows. (See www.realmilk.com.)
