Montmorency Tart Cherries May Help People WIth Metabolic Syndrome
Metabolic syndrome increases the risk of cardiovascular disease and type 2 diabetes. A new study has found that Montmorency tart cherries may help reduce that risk by improving blood pressure and serum insulin levels in people with metabolic syndrome.
Eleven people between the ages of 37 and 61 with metabolic syndrome participated in the study. They all underwent three interventions, receiving either Montmorency tart cherry juice containing the equivalent of 100 cherries, Montmorency tart cherry capsules made from 100 tart cherries, or a placebo.
The study period lasted six weeks, which were divided into three testing sessions. The testing sessions lasted six hours and were followed by a 14-day washout period. The researchers measured height, weight, waist circumference, arterial stiffness, blood pressure, heart rate, cardiac volume, stroke output, mean arterial pressure, glucose and insulin levels, insulin resistance/sensitivity, and blood lipids before each testing session and at the end of each testing session.
The researchers found that Montmorency tart cherry juice significantly reduced systolic blood pressure two hours after consumption compared to placebo. Montmorency tart cherry juice and Montmorency tart cherry capsules significantly reduced insulin concentrations in the blood one hour and three hours after consumption compared to placebo.
The study was conducted by researchers from the University of Hertfordshire. It was published online ahead of print on April 16, 2019 in the Journal of Functional Foods.
