London – Instead of eating less saturated fat and worrying about so-called bad cholesterol, a group of doctors suggests an alternative approach for preventing heart disease.

More important, they say, is to focus on decreasing insulin resistance and inflammation in the body by targeting diet, exercise and reducing stress.

“If we target all those three things together (plus) a reduction of smoking then we’ll combat 80 percent of all heart disease,” said Dr. Aseem Malhotra of Lister Hospital in Stevenage, UK, who coauthored an editorial in the British Journal of Sports Medicine.

Saturated fats are mostly found in animal products like beef, butter, cheese and other dairy.

Blaming coronary artery disease on saturated fat that clogs arteries is “just plain wrong,” according to Malhotra and his two coauthors.

In their editorial, the three experts cite a 2015 review of past research that found no link between a diet full of saturated fats and an increased risk of coronary heart disease, type 2 diabetes, stroke due to clogged arteries, death from coronary heart disease, or death from any cause.

Malhotra told Reuters Health, the traditional advice to reduce levels of “bad” low-density lipoprotein (LDL) cholesterol through diet and exercise “is flawed.”

He and his colleagues point to studies in which people who replaced saturated fat with vegetable oils containing omega-6 fatty acids did lower their LDL and total cholesterol levels but still ended up with a higher rate of death.

They also cite the well-known PREDIMED trial, in which people eating a Mediterranean diet with fats from olive oil or nuts were at lower risk of heart problems than people following a low-fat diet.

The best way to predict heart disease risk, they write, is to look at patients’ ratio of total cholesterol to “good” high-density lipoprotein (HDL) cholesterol. A high ratio is linked with insulin resistance, which leads to high blood sugar and higher risks for heart disease, type 2 diabetes and obesity.

Malhotra said insulin resistance is worsened when low-fat dieting leads people to eat more refined carbohydrates like white bread and white rice, which are not found in Mediterranean diets.
