Let's worry about other things How about education? Let's keep laws to a minimum, and up the education. If trans fat is so bad, let's educate people about it. If enough people decide they don't want to consume trans fat, the markets will change, and products containing it will be less common. Banning something just because it's a little harmful is a waste. It angers those of us that want to have freedom to choose for ourselves. I want to make my life instead of having somebody else choose for me.
Nicotine is more addictive than sugar I have never smoked, but I have seen people attempt to quit smoking. Most people fail at kicking the nicotine addiction. Equally, I have never tried to stop eating sugar, but I know plenty of people who have done that for a time. Those who stopped eating sugar ended up complaining much less about stopping than those trying to quit smoking.
