Saturated fat pledge 'a drop in the ocean'

England: A pledge by food manufacturers to cut saturated fat levels is "a drop in the ocean" in the fight against obesity, a top public health expert has said.

Morrisons, Subway and Nestle are among firms signed up to the voluntary "responsibility deal" between industry and government.

But Prof John Ashton, president of the Faculty of Public Health, said the approach "lacked credibility".

The Department of Health (DoH) said it would "make a huge difference".

It says the average man should eat no more than 30g of saturated fat a day, while the average woman should eat no more than 20g.

According to the British Dietetic Association, most people eat about 20% more than the recommended maximum levels - and a survey of 2,000 people for Sainsbury's found 84% of those questioned did not know how much saturated fat was a healthy amount.
