Chief among them is sugar (especially added sugar...bad for adults, even worse for kids), but also processed meats, vegetable oil, mercury in some seafood, etc. etc. So your Japanese books won't kill you, but the coke or ham sandwich you have while reading them might. And there's nothing the FDA can do to help you. Only you can keep up with the latest scientific research on this stuff, and choose what you eat.
I wouldn't put too much faith in the latest scientific research either, to be honest. Lets consider how it was considered that fat was universally bad, and then maybe just unsaturated fats are bad or maybe transfats, and oh wait, actually fats are essential nutrients and actually all those low-fat diets are ruining your health and those starches you're eating instead are worse for you and giving you diabetes while the lack of fats is ruining your mental and physical health...
The only thing that seems certain in the ever-changing nutritional landscape is that eating lots of fresh fruits and veggies is good for you, everything else is questionable, but you probably can't live on berries and celery alone so you better take a chance.
Nutrition is a very complex subject and we're nowhere near knowing what 'ideal' nutrition actually looks like, and ideas propogated by the 'latest science' can be extremely harmful (e.g., margarine instead of butter, e.g., 'low-fat' foods).
We know what yesterday's misunderstandings are, but what are we being told today that is actually flat out wrong...?
This is a very difficult area that is really poorly understood. I would avoid eating too many big predator fish (swordfish, salmon, tuna), try to eat more small fish (anchovies, sardines, kippers, tilapia) -- the dangers of concentrated heavy metals and the benefits of fish-oils seem pretty likely to be actual facts; obviously eat lots of fruits and veggies. Beyond that it gets pretty questionable... are vegetable oils bad? Trans-fats are, but those naturally occur in animal fats and unnaturally occur in processed vegetable fats. How bad are natural vegetable fats or natural animal fats? Is there a big difference between one vegetable fat and another, or one animal fat and another? Nobody really knows, truth be told, but we do know that you have to eat 'enough' fats to be healthy, just not 'too much' fats, but we can't actually define 'enough' or 'too much'.
Conversely, the dangers of radiation are actually very well documented and researched, at least at the high end. It's just not well understood by most people, and nobody seems to be doing a good job of making the science comprehensible. At the low end, there is evidence that insufficient background radiation is actually unhealthy but the science there is not in a good state. Nobody wants to do the research (or very few people anyway) to prove that radiation can be good for you. There's still a huge stigma to that kind of thing even though almost nobody remembers radioactive toothpaste that made people's teeth fall out from radiation poisoning and a whole other host of radioactive consumer products. Even though the details aren't recalled the stigma against calling radiation 'good' under any circumstances persists and even effects things like using gamma rays to sterilize, which is a completely different phenomenon from particle radiation. (There's a whole lot of reasons to think we'd be better off eating gamma ray sterilized foods rather than heat sterilized foods, but irrational fear of 'radiation' and confusion between ray and particle radiation means it's not even on the table as a possiblity.)
So... in short... uh.... in short, I lost my point. I think it had something to do with science being incomplete and the masses being stupid, but I'm not sure. Maybe it had to do with me being stupid and this post being incomplete...
I'll leave it here anyway for reasons, or no reason. Whichever.
