After moving the portable henhouses to a fresh pasture with his tractor at dawn, Virginia farmer Joel Salatin heads back to the barns to help rotate cattle from one pasture to another. (From the book What I Eat: Around the World in 80 Diets.) The caloric value of his day's worth of food on a day in the month of October was 3,900 kcals. He is 50; 5 feet 11 inches and 198 pounds. Much of his daily fare is from his own farm, including applesauce and apple cider canned by his wife, Teresa, who fills the basement larder with the bounty of their farm each year.
