According to Wrangham’s research, our human ancestors who started cooking between 1.8 million and 400,000 years ago presumably had more children who survived and grew up to be healthy adults. Because pounding and heating food “predigests” it, our digestive systems require less effort to break it down, are able to absorb more nutrients than they would if the meal were raw, and are able to derive more fuel for our brains as a result.
Why is cooking food necessary for humans?
Raw meat has a higher caloric and nutritional content than cooked meat, but raw meat requires more effort from the human jaw muscles and digestive systems to chew and digest than cooked meat does.
