I think that the American diet is a very large part of the reason we're spending 2.3 trillion dollar per year on health care in this country. 75% of that money goes to treat chronic diseases, preventable chronic diseases, most of those are linked to diet.
Very simply, we subsidize high-fructose corn syrup in this country, but not carrots. While the surgeon general is raising alarms over the epidemic of obesity, the president is signing farm bills designed to keep the river of cheap corn flowing, guaranteeing that the cheapest calories in the supermarket will continue to be the unhealthiest.
...There's a lot of money in the Western diet. The more you process any food, the more profitable it becomes. The healthcare industry makes more money treating chronic diseases (which account for three quarters of the $2 trillion plus we spend each year on health care in this country) than preventing them.
