A new study published in the Canadian Medical Association Journal shows that metabolic syndrome could be reversed by following a Mediterranean diet. Metabolic syndrome is defined as having three or more risk factors for cardiovascular disease or diabetes. Risk factors include abdominal obesity, high cholesterol, high blood pressure and high blood glucose levels. For this study, researchers investigated the metabolic effects of a Mediterranean diet, which in their opinion, is recognized as one of the healthiest diets. It involves high consumption of fruits, vegetables, whole grains, legumes and nuts, reducing intake of red meat, eating fish and poultry at least twice a week, and replacing butter with healthy fats – such as olive oil. In 2013, Medical News Today reported on a study claiming the diet can reduce the risk of heart attack and stroke in high-risk patients, while a more recent study suggested that children who eat a Mediterranean diet are 15% less likely to be obese.
