The New York City Board of Health took a step closer to banning trans fat in all city restaurants. Many doctors think that trans fat is bad for your heart. It probably is. But it shouldn't be banned in a free country.
The model that the fat banners use is the smoking ban in New York public buildings, including restaurants. I support a smoking ban in most places, including restaurants. Personally, I would let people smoke in bars, since people go to bars in the first place to do things that are bad for them.
The point is, though, that second-hand smoke is bad for other people beside the smoker. Second-hand fat is not even a meaningful concept. The Board of Health might spend its budget trying to convince people that trans fat is bad for them, and telling them all the kinds of food it appears in. They might require labels on all trans fat foods. They might even make fun of fat people.
But banning fat is just too intrusive. It gives some reality to the insult, "health Nazis."
