Study Notes
The Biological Adaptation to Cooked Food
- Animals, including wild species, prefer cooked food over raw food, whether it is meat or plant material.
- Humans are biologically adapted to eat cooked food, unlike cats and dogs who are adapted for raw food.
- Richard Wrangham argues that cooking is not just an epiphenomenon but a universal human need, contradicting the old view.
- The Atwater system for calorie information is based on burning food and is misleading because it doesn't account for the calorie benefit of cooked food.
- Cooked food provides more energy for reproduction and is easier to digest than raw food, leading to higher calorie intake.
- Cooking starch and denaturing protein increases digestibility, making cooked food more energy-efficient.
- The transition to a cooked diet is believed to have occurred around the time of Homo erectus, approximately 1.9 million years ago.
- Changes in skeletal structure and teeth, such as smaller teeth, indicate a shift to a softer diet with the advent of cooking.
- The consequences of cooking include early weaning of human children and reduced need for chewing.
- Australopithecines like Lucy were bipedal and could climb trees, while Homo erectus had adaptations for endurance running, potentially fueled by a cooked diet.
- The meat-eating hypothesis of human origins suggests that cooking played a crucial role in human evolution.
- Cooking has significant implications for human development, from changes in diet to physical adaptations, making humans dependent on cooked food for survival.
