protecting consumers from themselves

We put warning labels on cigarettes, but not on alcohol.  We put warning signs on the train platforms, but not on fatty foods.

Where should we draw the line?

Why do we put nutritional labels in numbers and scientific terms, when cigarettes get an ominous death label? 

Would you eat that burger if it came with a warning label?  Would you buy that venti latte or morning muffin if came with a warning label?

It seems we put ridiculous warning labels on everything BUT food.  And when we do put proper labels on food, it works! 

So what's stopping us?

Kudos to Jeff Jarvis for getting this conversation going!
