Salon.com Life | How cooking makes you a man: "Cooking doesn't change the actual number of calories in food -- meaning that, if you take two portions of raw vegetable or animal product and cook one of them, when you blow it up in a bomb calorimeter and compare the two, you'd get the same number of calories. But there are two big things that cooking does. One is that it increases the proportion of the nutrients that our bodies digest, and from the data I reviewed -- for instance, in the case of egg protein it goes from 50 percent to 90 percent -- it looks as though that effect can make an enormous difference. And the second thing it does is that cooking reduces the costs we pay to digest our food."
Wow, even bigger then I thought.
