Blueberries have been found beneficial to heart health in a recently published study. According to a new British research conducted by the University of East Anglia, consuming 150g of blueberries a day reduces the risk of developing cardiovascular disease.
Published in the American Journal of Clinical Nutrition, the study investigated whether the consumption of blueberries had an effect on the metabolic syndrome, a set of metabolic disorders that increases the risk of heart disease and that is most often reflected with high blood pressure, excess abdominal fat and high levels of lipids (fats) and glucose (sugars) in the blood.
“Previous studies have indicated that people who consume blueberries regularly have a reduced risk of developing cardiovascular diseases such as type 2 diabetes. This may be explained by the fact that blueberries are rich in natural compounds called anthocyanins, which are the flavonoids responsible for the red and blue color of the fruits, “explain the authors of the study in a statement.
For six months, the team of scientists observed and studied the effects of daily consumption of blueberries in 138 overweight and obese people aged 50 to 75 years who affected by the metabolic syndrome.
The experience has been to compare the benefits of eating 150g (the equivalent of a teacup) of blueberries compared to 75g servings. Participants consumed blueberries in freeze-dried form and a placebo group received a purple-colored alternative made from artificial colors and flavors.
A reduced risk of 15%
“We found that consuming one cup of blueberries a day, 150g, resulted in a steady improvement in vascular function and arterial stiffness, which makes a difference to reduce the risk of cardiovascular disease from 12 to 15%, “notes Dr. Peter Curtis, co-author of the study.
“Surprisingly, we have found no benefit from a smaller daily dose of 75 grams (half cup) of blueberries in this risk group. It is possible that higher daily intakes are needed for the benefits on the heart health of people who are obese and at risk for heart disease,” he adds.
Based on these findings, researchers recommend that people with Metabolic Syndrome consume one cup of blueberries a day to improve their heart health.
