A study by I. Muraki (et al.), “Fruit consumption and Risk of Type 2 Diabetes: Result from Three Prospective Longitudinal Cohort Studies,” British Medical Journal, vol. 347, 2013, examined the fruit consumption of 12,198 participants who had type 2 diabetes. The researchers examined the consumption of fruit juice versus the consumption of the raw fruit.
It was found that those who consumed one or more servings of fruit juice per day, increased their risk of developing type 2 diabetes by up to 21 percent.
However, the consumption of whole fruit – particularly apples and blueberries – resulted in a 7 percent reduction in type 2 diabetes risk.
