Metabolic Syndrome reversed by Mediterranean diet.

dietMetabolic syndrome is defined as the presence of three or more factors such as large waist circumference, high blood pressure, low HDL-cholesterol, high levels of triglycerides and high blood sugar. The syndrome has been linked to diabetes, heart disease and death.

The findings, from a clinical trial published in the Canadian Medical Association Journal, may help reverse the condition, as it was determined that a Mediterranean diet supplemented with extra virgin olive oil or nuts helps reverse the condition.

The study participants included 5801 people; 64% (3707) had metabolic syndrome at the start of the study.
After a median follow up period of 4.8 years, the researchers found that people in the two Mediterranean diet groups decreased their central obesity and blood glucose levels and 958 participants (28.2%) no longer met the criteria of metabolic syndrome.

“In this large, multicentre, randomized clinical trial involving people with high cardiovascular risk, a Mediterranean diet supplemented with extra-virgin olive oil was associated with a smaller increase in the prevalence of metabolic syndrome compared with advice on following a low-fat diet,” writes Dr. Jordi Salas-Salvadó, Human Nutrition Unit, Faculty of Medicine and Health Sciences, Universitat Rovira i Virgili and Hospital Universitari de Sant Joan de Reus, IISPV, Reus, Spain, with coauthors.
