Wealthy and intelligent people make plenty of suboptimal choices.

Ironically the fittest people I know with the best diet (they eat like their grandmas used to) are quite rural and don't know anything about nutrition.

If they did they would probably fare worse. I obsessed over diet, spent countless hours studying thr subject and reviewing the latest in nutrition science. I wonder how much of that was funded by Nestle. I tried a processed vegetarian diet for a decade before having health issues and ending up eating only meat. After 1 year of that I was able to reintroduce small amounts of carbs / veggies without having adverse reactions, but at this point I don't even care about doing it.
