> Americans treat our bodies like garbage bins for sugar and fat.

Even this isn't so simple. Foods in America are engineered explicitly to increase consumption, often (but not exclusively) by increasing fat, sugar, and salt. A good example of this is bread, as most breads sold in the US would be classified as cake in other countries due to the added sugar.

The only way to avoid this is to make your own food by scratch, which simply isn't viable for a large population living paycheck to paycheck.
