COPENHAGE - Denmark Saturday became the first country in the world to impose a fat tax after a week in which consumers hoarded butter, pizza, meat and milk to avoid the immediate effects. We have had to stock up with tonnes of butter and margarine in order to be able to supply outlets, Soeren Joergensen of Arla Distribution told AFP. The new tax, designed by Denmarks outgoing government as a health issue to limit the populations intake of fatty foods, will add 16 kroner ($2.87, 2.15 euros) per kilo (2.2 pounds) of saturated fats in a product. This means an increase in the price of a pack of 250 grammes of butter, for example, by 2.20 kroner to more than 18 kroner.
