The raw truth about cooked foods

Raw food provides less energy than cooked - Health - CBC News: "Cooking food boosts the amount of energy your body can get from it — and hence the weight you gain by eating it.

That applies to both meat and potatoes, and likely had a profound effect on human evolution, says a study published this week in Proceedings of the National Academy of Sciences.

It also means that current food labels — which list the same number of calories for ingredients whether they are raw or cooked — are inaccurate, suggests Rachel Carmody, a researcher at Harvard University and lead author of the study.

Evolutionary biologists had long suspected that the human diet became significantly more energy rich in the past two million years due to changes in the human body that make it require more energy, said Carmody, a graduate student specializing in human evolutionary biology."
