Science is inventing new food all the time, which is great for those of you who've tried all of the existing foods already. The problem is that we humans will start wolfing this stuff down long before science fully understands its effect on our bodies. Some problems take decades to appear, or only show up in a few ultra-specific circumstances.
For example, the common foods below all seem to have some kind of weird effect on the human brain (or at least, are correlated with some weird effect, for reasons no one understands). I'm not warning you off of consuming any of these, but it's still worth knowing what the experts are saying ...
Note: I am the opposite of a doctor. If you think your diet is messing with your body or brain, please call a professional! A medical professional, obviously. Not, like, a professional wrestler or something.
Jerky Has Been Linked To Manic Episodes
If it was feasible, I would eat beef jerky for two meals a day, every day. I am a man of simple tastes (too simple, some would argue, as this diet would surely kill a person within a month). However, recent studies suggest there may (MAY) be a weird, completely unexpected side effect. Salty, cured meats may be leading you down the road to manic episodes -- that is, the kind that require hospitalization.
In a study that covered 1,100 people, researchers discovered that subjects who had eaten cured meats were 3.5 times more likely to have been hospitalized for some kind of mania than those who hadn't. Mania, to be clear, is defined by a super positive mood, ultra-high energy, feelings of confusion, and a disconnection from reality so severe that you need medical help. So not a super good thing. The study didn't prove that mental health suffers from ingesting those foods; it just noticed a very odd correlation between the two things. It possibly has to do with the nitrates most of those products contain.
