NEWS YOU CAN USE: Saturated fat ‘ISN’T bad for your heart’: Major study questions decades of dietary advice.

After decades of advice on the harm done by saturated fat such as butter, scientists have found no evidence of a link with heart problems.

A ‘mega’ study which analysed a huge amount of existing data also said so-called healthy polyunsaturated fats, such as sunflower oil, had no general effect on the risk of heart disease.

In contrast, a dairy fat called margaric acid ‘significantly reduced’ risk, while two kinds of saturated fat found in palm oil and animal products had only a ‘weak link’ with heart disease.

Two types of omega-3 fatty acid found in oily fish – EPA and DHA – and the omega-6 fat arachidonic acid were linked to a lower risk of heart disease. But omega-3 and omega-6 supplements appeared to have no benefit.
