I think a better idea is to do away with all the subsidies for sugar, corn, and meat products, but since that's not going to happen...
Of course we've bought our way into this citation by subsidizing an unhealthy diet. The cheapest foods in America today are full of sugar and/or fat because of our policies protecting such industries. The American diet is also loaded with meat products because of similar legislation, and such diets are rapidly spreading around the world because of these decades old policies that need to be reversed, but likely never will.
