Metabolic syndrome is characterized by risk factors that increase an individual’s chances for cardiovascular disease. These risk factors include obesity, hypertension, high cholesterol and uncontrolled blood glucose. In addition to cardiovascular disease, those with metabolic syndrome are at increased risk for type 2 diabetes. The Mediterranean diet is considered by many dieticians as a viable option for those suffering from diabetes and hypertension. A previous study with a one year follow-up has shown the diet’s ability to reverse metabolic syndrome.
The purpose of this study was to use a longer follow-up of 4.8 years to determine the long-term impact of the Mediterranean diet on metabolic syndrome. Subjects were randomly assigned to one of three groups: Mediterranean diet with supplemental extra virgin olive oil, Mediterranean diet with supplemental nuts or advice for following a low-fat diet. The primary outcome for this study was metabolic syndrome status, both incidence and reversal. Having metabolic syndrome was defined as having at least three of the cardiometabolic risk factors previously discussed. Cox regression analysis was used to determine the hazard ratios and to calculate the confidence intervals.A supplemented Mediterranean diet can lead to metabolic syndrome reversal...,
