No, there has to be some common sense. I do know that you are what you eat, and if you put junk in your body the result will be a junky body. The United States is probably the number one obese country in the world, and I am positive part of that is the result of junk food. Like most things if you want long term results you have to start early, and right now people start early with junk food and then spend the rest of their life trying to change their habit and find that it is very difficult to do. Look at all the diets on the market.
Smoking is the same way.
Why do the cigarette manufactures try to get the young hooked, because then they have an income for life. The fact that they are shortening yours is no concern to them. The snack food industry, likewise, does not care if they are strangling your heart or clogging your circulatory system. Its your choice, eat it or don' t eat it. To cut this discourse short, I guess that I would not have a problem with the USDA's proposal.
