2. Researchers from the University of East Anglia and other institutions published papers in the new issue of American Journal of Clinical Nutrition. They recruited 65,438+038 overweight or obese volunteers, all aged between 50 and 75, who suffered from metabolic syndrome, that is, they were at high risk of heart disease, stroke and diabetes.

During the six-month observation period, the researchers asked some people to eat freeze-dried blueberries every day, while others ate artificially colored "fake blueberries", that is, placebos. People who eat freeze-dried blueberries every day are divided into two groups. One group eats 150g (about a small bowl) every day, and the other group eats 75g (about half a bowl) every day.

4. The results showed that people who ate 150g blueberries every day continued to improve their vascular function, which could be translated into a reduction in the risk of cardiovascular disease from 12% to 15%. However, people who eat 75 grams of blueberries every day have no obvious improvement in related functions.
