A bowl of wild blueberries a day could protect against a range of health problems including obesity, heart disease and diabetes.
Regular consumption of the berries over an eight-week period can improve or prevent metabolic syndrome, researchers say. Metabolic syndrome is the medical term for a combination of diabetes, high blood pressure and obesity. It increases the risk of heart disease, stroke and other conditions affecting blood vessels.On their own, diabetes, high blood pressure, and obesity can potentially damage the blood vessels, but having all three together is particularly dangerous. Berries are rich in polyphenols - antioxidants that protect cells in the heart and help lower blood pressure. This means they may help reduce damage to the lining of blood vessels and tackle glucose intolerance - excess sugar in the blood that can lead to diabetes.
