What has obesity to do with hearts? Lots. Icelandic cardiologist Dr Axel Sigurdsson spoke recently at a meeting mostly of cardiologists and endocrinologists.
He discussed, among others, the current status of diet-heart hypothesis that saturated fat causes heart disease. And the possible relationship between fear of dietary fats and the obesity epidemic.
After the meeting, a senior colleague, an old friend and mentor, who Sigurdsson highly respects, lambasted him privately. The colleague said that the mortality from heart disease had dropped dramatically for the last 30 to 40 years. He said that was mostly from dietary changes to lower blood cholesterol.
He was angry with Sigurdsson for asking: has the emphasis on low-fat food products ultimately steered us into an epidemic of obesity, metabolic syndrome and diabetes? Here, Sigurdsson explains how and why low-fat diets contribute to obesity and a whole lot more. – MARIKA SBOROS
