In fact, obesity may get worse...in the scramble to produce more food, costs need to continue to come down, which means additional additives for shelf stability and flavor...high fructose corn syrup being just one example. It's a travesty when a gallon of water costs more than a gallon of soda. I'm doing my part by having my own garden, as are our neighbors. I also cook almost all meals, so freshness and flavor are guaranteed without all the additives. I recently saw a show that stated in the 1800's families spent 10 cents per dollar on food, that figure today is 70 cents per dollar. People simply grew most of their own food.
If anyone has more accurate info, that would be great. Please share.
