Should TV Ads Disclose Calories?

I am a fan of your work, and am writing to ask your opinion of an idea.

Can you think of an appropriate lobbying group to consider demanding that all TV food advertisements carry a listing of calories, fat, and sugar content? I was watching a TV show that had several ads for restaurant meals, hefty desserts, etc and realized how seductive such ads can be. Perhaps, if we viewers saw that a certain ice-cream creation had over 1,000 calories and 40 grams of fat, we might not hop in the car for a fix.

If alcohol ads have ‘Drink Responsibly” all over them on TV, and cigarettes only show up in print ads but still with the Cancer warnings, could not food ads have a simple listing of the three common obesity triggers?”

Opinions, please. Would something like this be useful?
