Here's the real reason why Americans are fatter than everyone else...studies showed that U.S. fast-food is deliberately made fattier and more unhealthy than in other countries. The reason? They use hydrogenated oils in this country, which is cheaper. The fast-food companies claim it's because of local preferances. The real reason? Americans are more tolerant of fat and want to pay less for food. But countries like Denmark or Britain wouldn't tolerate that kind of thing. And then they wonder why Americans are gaining weight. This is why I saw Supersize Me again. It was a real wakeup call into the fast-food industry. And the new movie, Fast Food Nation, looks poised to do the same thing.
