Saturated Fats And Heart Disease: No Link Found

By Joe Tidy, Sky News Reporter

A massive international study of 600,000 people's diets has found saturated fats like butter may not be as unhealthy as first thought.

For decades, health advice has been to cut down on saturated fats - found in butter, biscuits, fatty cuts of meat, cheese and cream.

And instead people were urged to eat polyunsaturated fats - found in olive and sunflower oils and other non-animal fats.

However, research led by Cambridge University scientists, indicates there is no evidence to support current guidelines which restrict eating saturated fats to prevent heart disease.

The team collated results from 72 unique studies from 18 different countries and also found "insufficient support for guidelines which advocate the high consumption of polyunsaturated fats (such as omega 3 and omega 6) to reduce the risk of coronary disease".

The findings are at odds with decades-old advice on how to eat healthily to take care of our hearts.

Current NHS guidelines say a diet high in saturated fat can raise the level of cholesterol in the blood and increase the risk of heart disease.

Men are not recommended to eat more than 30g of saturated fats and women no more than 20g.

However, most of us eat 20% more than this, which is considered to be unhealthy.

Dr Rajiv Chowdhury, the lead author of the research, said: "These are interesting results that potentially stimulate new lines of scientific inquiry and encourage careful reappraisal of our current nutritional guidelines.

"In 2008, more than 17 million people died from a cardiovascular cause globally.

"With so many affected by this illness, it is critical to have appropriate prevention guidelines which are informed by the best available scientific evidence."

The British Heart Foundation, which commissioned the research, says the findings could mean it is time to look into this accepted wisdom.

The organisation is calling for more studies to clarify what is good and bad for our hearts.

But is stresses that the findings do not mean it is fine to eat lots of cheese, pies and cakes.
