The health foods doctors say don't work:


Dr Aseem Malhotra, lead cardiologist of the National Obesity Forum, says:

I don’t go near Benecol or any other margarine-type products that claim to lower cholesterol and I advise my patients to stay clear of them, too. 

First, they are expensive; second, these products are artificial, packed with unnatural products that really can’t do you any good; and third, I don’t believe there is any demonstrable health benefit.

They may have a very marginal effect on cholesterol, but — and this is critical — this hasn’t been established as having any clinical benefit in reducing the risk of a heart attack. In short, the whole saturated fat argument has been ridiculously overhyped. 

A review of studies in the American  Journal of Clinical Nutrition in 2010, which analysed almost 350,000 people for up to 23 years, revealed no consistent evidence  linking saturated fat and cardiovascular disease.

In fact, I’ve started advising my patients to have butter, though clearly in moderation. 

Really strong data is increasingly showing that the saturated fat from natural dairy products may even be beneficial in reducing heart attacks. It’s thought this is because it contains essential vitamins, such as A and D, as well as essential nutrients such as calcium and phosphorus, which studies  suggest can reduce the risk of heart disease and stroke.

Other research, by Dr Dariush Mozaffarian from the Harvard School of Public Health in Boston, found that people with higher levels of the trans-palmitoleic fatty acid (found mainly in dairy products) in their blood were about 60 per cent less likely to develop  type 2 diabetes over the next 20 years than those with the lowest levels. 

Again, this runs counter to long-standing recommendations to trade in whole milk and cheese for the skimmed varieties.
