Is nutritional health always uncertain?

This section has been dominated by this 1 dude who talks about his possibly hot body. Days later I ran into a reddit comment about how nutritional info constantly changed, which I then lead myself into this thread. https://www.reddit.com/r/explainlikeimfive/comments/2dwrr8/eli5_why_does_there_seem_to_be_so_much/

Why is it that when it comes to nutrition nothing is ever concrete? It's more like "this causes this, no wait this thing really does that" "actually don't eat it its bad" "but its good if u have this" "no ur wrong aosdkfalk!"

So much confusion over what nutrients we need, what foods give them, and on top of that our own lifestyle and medical information must be taken into account as well. Is kale really healthy as people say it is or does it have some hidden killing mixture within it? What else will we find about kale and is it even true?

It's no secret (well.. now it's not) that fast food causes fat, it has lots of grease and oil in the first place. The confusion starts when you look closely into certain types of foods or foods we never look into. I mean some people eat more because they do more, so it makes sense, but not doing more makes you fat. I'm no nutritionist so I really don't think I know any better than anyone else. I question them though because nothing seems to be stable, even the food pyramid has been adjusted. Like there are people who question the healthiness of grains. There are people who do some mystical diet and it may or may not work. It's all a mystery to me except the very basics. Sugar & oil = fat, and natural whole foods = healthy. But whole foods is difficult to find or pay because who wants to grow food that dies or spoils often and sell it for cheap? This kind of goes into the whole pesticide/GMO section. Who's even giving that new info anyways can it be trusted or is it just trying to sell you something?

Lots of past research has been skewed by companies trying to avoid harm and promote sale. This only makes what information we've gathered over the years even more confusing. Like sugar companies tried to but most of the fat blame on oily foods. I also heard cold cereal is a breakfast thing to sell more processed sugary corn products. You get the idea.

And whoever experiments diets on humans.. that can't work. We're too complex in other ways, like some of the people being testing might have some developing disease nobody's aware of. Or maybe someone else lived in a more polluted area than someone else.

And another thing about natural foods, how natural do we go? Because technically the whole foods we eat are not natural, bananas aren't supposed to look like that and never did at first anyways. Cooking isn't natural, we started that stuff, but if we eat raw we may get sick. It seems to me it's a sort of death by pathogens vs death by chemicals. Wild animals don't live as long as those in captivity, credit for the medicine, but I'm sure we do our best to make sure the food we feed them is also at the very least not dangerous. I don't know man, I guess if you can see a doctor you can record your ever changing diet to find the best one unique to your body and lifestyle. That's probably why United States have some pretty unhealthy people.

tl;dr: diet is too confusion except that natural foods is good, and processed food is not, but then you gotta look at your wallet. Research in diet is more confusing than tangled spaghetti. You are more complex than a chart.
