Sugar

According to some experts the Americans are fat because they eat shitloads of glucose–fructose corn-syrup which is a cheap-arse supplement for sucrose. The use of the glucose–fructose version apparently screws their pancreases and makes them get fat very easily.

Not that they should be eating that much sugar anyway but its hard to avoid because it is used as an unlabelled food additive in just about everything, even where sugar isn’t needed. Its like they have a collective Jonestown pact going down.
