True for many things I guess. I don't know any more than you - I'm just looking it up:

Cooked items are often listed as having fewer calories than raw items, yet the process of cooking meat gelatinizes the collagen protein in meat, making it easier to chew and digest—so cooked meat has more calories than raw. ... The way foods are processed can also make them easier to digest. Take "resistant" starch in cereal kernels, such as barley grain, or beans, which take a long time to digest. But grind the same cereals into flour or process it into breakfast cereal or instant oatmeal, and it becomes easy to digest, said biochemist nutritionist Klaus Englyst of Englyst Carbohydrates Ltd., a carbohydrate chemistry firm in Southampton, U.K. This is why "bread is more rapidly digested; beans more slowly," he said.

I guess modern scientists are questioning the whole system behind current nutrition labels, which is simplistic and outdated.
