Well, by that logic pretty much anything should be outlawed that you can do to your body. Including trans fats and crunch chicken skin. Both are very dangerous, especially in large quantity.
The problem with that logic, is you are falling for the lies that have been propagated for the last few decades. Your example of trans fats and chicken skin are particularly insightful as the scientist that came up with the fat is bad for you studies threw out half of the data so he could get a curve fit that he wanted to see. one link on this subject. It is well know that studies have shown the fake sugar stuff makes people and rats fatter, not thinner. Margarine also does tricks that end up being less healthy than just eating butter. And using vegetable oil is much worse for you than using coconut oil or even just plain old bacon fat. (My family now uses bacon fat to cook and our health and weight has improved.)
So letting some group decide what is healthy and un-healthy just leaves you open to being manipulated and controlled by those with power over the laws. I don't want anyone telling me I have to eat some crap than causes anal leakage or turns your eyes brown permanently just because they have stock in the company and will make a ton of profit if they can make the laws say you are required to eat their crap because it has been deemed to be the healthy thing to do.
