What country was the first in the world to impose a tax on fatty foods?

Denmark

Answer: In October 2011, Denmark introduced a fat tax on butter, milk, cheese, pizza, meat, oil and processed food if the item contains more than 2.3% saturated fat. The fat tax was the first of its kind in the world. Although the tax resulted in an additional $216 million in revenue, it also led to numerous complaints. In November 2012, the fat tax was abolished, because it failed to change Danes’ eating habits, had encouraged cross border trading, put Danish jobs at risk and had been a bureaucratic nightmare.
