Blueberries' has effect on heart, metabolic syndrome

Among all fruits, berries have shown substantial cardio-protective benefits due to their high polyphenol content. However, investigation of their efficacy in improving features of metabolic syndrome and related cardiovascular risk factors in obesity is limited. Researchers publishing a Journal Nutrition study examined the effects of blueberry supplementation on features of metabolic syndrome, lipid peroxidation, and inflammation in obese men and women.

Decreases in systolic and diastolic blood pressures were greater in the blueberry-supplemented group than in controls, whereas the serum glucose concentration and lipid profiles were not affected. The decreases in plasma oxidized LDL were greater in the blueberry group than in the control group.

The study concludes that blueberries may improve selected features of metabolic syndrome and related cardiovascular risk factors at dietary achievable doses.
