This is true, but you have to remember that we didn't evolve in a vacuum. There are nutrients in food that do not exist for our benefit, but our species has evolved to take advantage of a food that perhaps some earlier species could not. It may be milk or it may be a banana. Some of us are able to digest one or both. Humans have had a long time to adapt to eating bananas and quite a bit less time to milk. Because of that, milk can be more problematic.
You know we all carry around the ability to digest insect shells. Just because you are able to digest a certain food doesn't mean you have to.
