The Food Police have stormed Denmark, where it is now a little more expensive to eat fattening food.

The country’s so-called “fat tax” went into effect on Saturday. The tax rate is 16 Danish kroner per kilogram of saturated fat in a food – in terms Americans can understand, that’s about $6.27 per pound of saturated fat – and it kicks in when the saturated fat content of a food item exceeds 2.3%.

The complex formula takes into account the amount of fat used to produce a particular food, not the amount that’s in the final product, according to Ole Linnet Juul, food director at Denmark’s Confederation of Industries. He calculated that the tax adds 12 cents to a bag of chips, 39 cents to a small package of butter and 40 cents to the price of a hamburger.

If this seems like a radical move, consider that Denmark has already banned the use of trans fats, which many doctors say is the worst kind because it raises bad cholesterol and lowers good cholesterol at the same time. Danes also pay sin taxes on sugary items like soda and candy. But the fat tax is believed to be the first of its kind in the world, Linnet Juul told the Associated Press.
