I'm a terribly picky eater. So terrible in fact, that there is a single green vegetable I'll consume and zero fruits. Sure, I'll eat things comprised of processed vegies (love me some pizza), but I won't sit down and eat a tomato, pees, bananas, etc. Okay, I eat potato's too, but that's a stretch. So while I haven't done any research on the matter, I'd say it's pretty conclusive I don't get a good portion of nutrient…
At the risk of sounding like someone's mother: snap out of that ridiculous picky eater nonsense. Unless you've got an actual medical condition that prevents you from eating certain foods you are likely doing yourself a hell of a lot of harm by only eating processed food. And spending your $ on supplements isn't going to make up for all the complex stuff in vegetables and fruits that you are missing.
Few people I know like or would willingly consume anything put in front of them. Surely there is something out there you wouldn't eat, don't like, etc. Why is it so hard to imagine that there are people out there (like me) who don't just have this adversion to eating a few things, but rather quite a few?
I'll finish by saying that in the interest of health, I most certainly should be forcing myself to eat things I don't particularly care for or even find downright disgusting. However, to assume that the reason I don't eat such things is nonsense isn't a fair assesment in my opinion.
