"Is a steak from a feedlot steer that consumed a diet of corn, various industrial waste products, antibiotics, and hormones still a “whole food”? I’m not so sure. The steer has itself been raised on a Western diet, and that diet has rendered its meat substantially different -in the type and amount of fat in it as well as its vitamin content- from the beef our ancestors ate. The steer’s industrial upbringing has also rendered its meat so cheap that we’re likely to eat more of it more often than our ancestors ever would have."
