When I was a kid I was bouncing off walls due to I think all the sugar I was eating. Breakfast was sugar cereal and then there was candy then soda. My gifts were 12 pack of coca cola and candy. Fast food is also no good if eaten all the time. Canned soup loaded with MSG also no good.
If I was going to school now the teachers would have me on drugs to calm me down instead of looking into what I was eating and drinking.
Yeah. The two big killers in the american diet are sugar and seed/vegetable oils.
