Eating more blueberries, apples and pears may be linked to lower risk of diabetes due to their flavonoid content, according in the American Journal of Clinical Nutrition, parallels a study published in the same journal last year associating flavonoid-rich fruits with a reduced risk of high blood pressure. None of the subjects in the study had diabetes at the outset, but about 12,600 of the participants were diagnosed during the research period.
The biggest blueberry consumers (two or more servings per week) had a 23 percent lower risk of developing type 2 diabetes compared with those who ate no blueberries. People who ate five or more apples a week also had a 23 percent lower risk compared with those who didn't eat apples.
Bonnie: this study aside, I still do not recommend eating fruit by itself. Always accompany it with a healthy fat or lean protein source.
