Diabetes protection offered by some fruits but not all

In pooled data from studies covering more than 200,000 US health professionals, researchers found protection against diabetes varied markedly among individual fruits, with little being conferred by, for example, rockmelon, citrus and stone fruits.

The associations were not accounted for by variation in the GI of individual fruits, the researchers said.

Intake of fruit juice was associated with a higher risk of diabetes, and replacing juice with whole fruit – even ‘non-protective’ fruit like peaches or oranges, reduced risk.
