I don’t think there is anything I eat only because it would be good for me.
I eat what I like.
I will eat what I don’t like if someone invited me and prepared it, without knowing I don’t like it.
I happen to like kale. Has to have had the frost going over it.
Then mashed with potatoes and rookwarst (smoked sausage) to the side. And jus.
And a little vinegar
Pretty much the traditional Dutch way of eating it, although some people will add a bit of mustard as well.
I don’t think there’s anything I eat specifically for some derived benefit, outside of just filling my belly/calories, and eating things I think are tasty.
My wife does eat a tablespoon of chia seeds sprinkled into her morning yogurt, I think purposefully for the fiber content. Not to mention a decent protein/glycoprotein boost.
My second daughter has wavy, verging-on-curly hair. She used to buy a product called “CurlCare” but now boils ands strains flax seeds to get a product she claims works even better, cheaper, and no chems. Not quite what you’re after, though.

Yes, the spread of sour bread is obnoxious imo
Huh! Someone finally agrees with me ! A chef, no less!
Does a glass of beer/cocktail/wine count - very functional for relaxing after a long day
I eat oatmeal mixed with oat groats every morning because it is good for me, they say. The ONLY way I will come near kale is if it is dino kale, well massaged, mixed with romaine kettuce in a lightly dressed Caesar type salad. I will only eat cauliflower, because it is good for me, raw as a crudité. I like the ice cream comment.
But is that the only reason for drinking the alcohol?
Good question - I guess many people are drinking alcohol mainly to relax
