Book excerpt: Why are human food habits so diverse? Why do Americans recoil at the thought of dog meat? Jews and Moslems, pork? Hindus, beef? Why do Asians abhor milk? In Good to Eat, best-selling author Marvin Harris leads readers on an informative detective adventure to solve the worlds major food puzzles. He explains the diversity of the worlds gastronomic customs, demonstrating that what appear at first glance to be irrational food tastes turn out really to have been shaped by practical, economic, or political necessity. In addition, his smart and spirited treatment sheds wisdom on such topics as why there has been an explosion in fast food, why history indicates that its bad to eat people but good to kill them, and why children universally reject spinach. Good to Eat is more than an intellectual adventure in food for thought. It is a highly readable, scientifically accurate, and fascinating work that demystifies the causes of myriad human cultural differences.
