A new study supports the recommendation of eating two servings of fruit every day to get health benefits — in such a case a decrease risk of diabetes.

Adults who ate two servings of fruit a day had a 36percent lower probability of developing diabetes in 5 years compared to people who ate less than a half serving of fruit a day, after adjusting for confounders, in a population-based Australian study.

The findings from Nicola P. Bondonno, PhD, and colleagues, according to data from the Australian Diabetes, Obesity, and Lifestyle Study (AusDiab), were published online June 2 from the Journal of Clinical Endocrinology & Metabolism.

The study also revealed a greater fruit intake was associated with higher insulin sensitivity and reduced pancreatic beta-cell operate in a dose-response method.

And also a higher consumption of apples — although citrus apples or fruit, the two additional fruits analyzed — was correlated with lower post-load serum glucose levels.

“This indicates that people who consumed more fruit [especially apples] had to produce less insulin to lower their blood glucose levels,” Bondonno, by the Institute for Nutrition Research, Edith Cowan University, Perth, Australia, clarified in a statement by the Endocrine Society.

“This is important since high levels of circulating insulin (hyperinsulinemia) can damage blood vessels” and this can be”related not only to diabetes, but also to high blood pressure, obesity, and heart disease,” she observed.

Fruit Juice Doesnt Have Same Effect

The study supports the recommendation of the Australian Dietary Guidelines — 2 servings of fruit a day, where one serving is 150 grams, which corresponds to a medium-sized apple, orange, or banana — Bondonno clarified in an email to Medscape Medical News.

However, fruit juice was not associated with better glucose or insulin levels, or lower risk of diabetes, possibly because of its relatively high glycemic load and fewer beneficial fibers, the researchers speculate, adding data suggest that even juice with added fiber does not trigger satiety.

The study findings”support encouragement of the usage of whole fruits, but not fruit juice, to preserve insulin sensitivity and mitigate [type 2 diabetes] risk,” Bondonno and colleagues summarize.

“Promoting a healthy diet and lifestyle that includes the consumption of popular fruits such as apples, carrots, and oranges, with widespread geographic accessibility, may lower [type 2 diabetes] prevalence,” they conclude.

Lower 5-Year Odds of Diabetes

It isn’t clear how eating fruit may confer protection from developing diabetes, the investigators write.

They aimed to analyze how intake of complete fruit, individual fruit, and fruit juice is related to glucose tolerance, insulin sensitivity, and incident diabetes in 5 Decades and 12 years in participants in the nationwide representative AusDiab study.  

They identified 7675 adults aged 25 and older with no diabetes who had undergone blood tests and finished a
