I'm not very knowledgeable in this topic, but I think it's changed a lot. The way food is processed changes the way we're absorbing it.

Today's bread, milk, cheese, veggies, fruits are a bit different than 50 years ago - they last longer, taste different, probably because of how they're processed.

That lack of bacteria that makes things go bad faster should have a different effect on our bodies, no?



That's got little to do with what I meant.

Replace "Nutrition", with "Nutrition Science" or "Our understanding of the body's need for Nutrition" in my comment.
