An abundance of food that we didn't coevolve with and thus isn't optimal nutrition.

Modern industrial foods have just shown up in the 3ish million years of homosapiens existence, hell, agriculture is still really new at 13,000 years.

Humans eating the coevolved foods won't have this type of reaction, i.e. animals meats and fats won't make even the most dedicated couch potato look like this guy.

Now.. eventually, in a few hundred thousand or millions of years eating current processed foods, the future humans will have adapted and be ok with it, but not today

We've already adapted via medical science and technology. There's no more evolutionary pressure to biologically adapt.

That's not true. Illness and injury still have an effect on reproduction. Someone who spends their life fighting chronic disease is going to have a worse time with sexual selection and reproduction. Plus a lot of characteristics are social in nature, with kin selection being a big part of human evolution, so those who are less able to contribute outside of their direct reproduction still detrimentally affect their genes' survival and propagation.

Yeah but bad traits are still MUCH more likely to be passed on
