Denmark introduces world's first food fat tax

Denmark has introduced what is believed to be the world's first fat tax - a surcharge on foods that are high in saturated fat.

Butter, milk, cheese, pizza, meat, oil and processed food are now subject to the tax if they contain more than 2.3% saturated fat.

Some consumers began hoarding to beat the price rise, while some producers call the tax a bureaucratic nightmare.

Others suggest that many Danes will simply start shopping abroad.

Danish officials say they hope the new tax will help limit the population's intake of fatty foods.

However, some scientists think saturated fat may be the wrong target.

They say salt, sugar and refined carbohydrates are more detrimental to health and should be tackled instead.
