By researchers from the Harvard School of Public Health, confirms the results of a previous study, also published in the same journal last year, which suggested that a greater intake of flavonoids through the diet was beneficial to health and, specifically, reduce the risk of hypertension. Flavonoids are also believed to be potential substances that can prevent various diseases, including heart disease and cancer.

Although there is no concrete evidence that taking blueberries, apples or pears in this case prevents type 2 diabetes, the association shown by the results is evident. In fact, “people who ate more blueberries or apples tended to have a lower risk of type 2 diabetes,” confirms Dr. An Pan, who coordinated the study. And the results confirmed this thesis even after adjusting possible other risk factors such as body weight, smoking habits and a family history of diabetes.

The answers to this have come from monitoring the eating habits of about 20,000 people of both sexes for a period of time that has touched 24 years, and which were part of three large studies funded by the American National Institutes of Health.

At baseline, none of the participants developed type 2 diabetes, however, during the observation years, approximately 12,600 people were diagnosed with the disease. The data obtained regarding the diet followed by the participants revealed that those who ate two or more servings of blueberries a week, as well as those who ate five or more apples a week, had a 23% lower risk of developing diabetes. type 2, compared to those who ate less than a cup a month of blueberries or few or no apples. “We found consistent results in all three study groups that apples and blueberries are beneficial for type 2 diabetes,” says Dr. Pan.
