Those three fruits are your best bets if you want to avoid Type 2 diabetes, Harvard researchers said this week.
But skip the fruit juice, with its high concentration of sugars.
The news from Harvard says eating whole fruits can lower your risk of developing Type 2 diabetes. Researchers examined three different long-running studies of the habits of 187,000 people -- 12,198 of whom were stricken with Type 2 diabetes.
Those who ate at least two servings a week of whole fruits -- especially those apples, grapes and blueberries -- reduced their risk for diabetes by as much as 23 percent compared to those who ate less than one serving a month.
Fruit juice didn't score as well. Downing one or more juice drinks a day actually increased the risk of getting diabetes by as much as 21 percent.
Now that's a glass half-empty.
