Because processed food with high fructose corn syrup is cheaper to buy and probably tastier, too. I bet if you followed those kids around, you would be surprised how little they eat... but how much of it is all the wrong stuff.
Highly processed, high fructose corn syrup foods are more expensive to buy all around.
I have heard that it is expensive to eat healthy before from a bunch of know nothing shop at “Whole Foods” idiots.
Eating healthy is cheap. Staple foods are cheap. Meat is cheap. Pizza rolls and frozen fish sticks and tatertots are expensive. Four, cheese, meat, vegetables, fish and potatoes are all DIRT cheap.
