Its an urban legend that modern humans are not evolving because, medicine. The bone record for the last 50,000 years shows more evolution than the previous 1M. Probably because civilization has selected for a smaller, lower-calorie, less-aggressive social individual who can thrive in a crowded village or town.

There are side effects in any rapidly-evolving creature. Sports and mutations survive because they are helpful. But they can be hurtful in other, non-fatal ways. I think modern illnesses (need glasses? have a food allergy?) are unfortunate side effects of a rapidly-changing genome.

Well there's a difference between evolution and natural selection. What I was implying was that our diet may not influence our evolution through natural selection because modern medicine may prevent us ridding ourselves of the bad mutations or may keep good mutations that will adapt to western diet from rising to the top. So it makes sense that we are more diverse because the best genes are less competitive. But genetic mutations occur no matter what we eat, so, yes, we'll continue to evolve.
