Some good news. A recent study found that eating just 2 servings (a cup) of fruit per day is associated with a 36% lower risk for type 2 diabetes after 5 years (as compared to those who eat less than 1/2 a serving) . Doesn't sound like so much fruit, but appears to have a big effect.
However, in this Australian study, the association did not hold for fruit juice. Only for eating whole fruits.
A new study finds people who consume two servings of fruit per day have 36 percent lower odds of developing type 2 diabetes than those who consume less than half a serving. The research was published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
Diabetes is a disease where people have too much sugar in their bloodstream, and it is a huge public health burden. Approximately 463 million adults worldwide were living with diabetes in 2019, and by 2045 this number is expected to rise to 700 million. An estimated 374 million people are at increased risk of developing type 2 diabetes, the most common form of the disease. A healthy diet and lifestyle can play a major role in lowering a person's diabetes risk.
The researchers studied data from 7,675 participants from the Baker Heart and Diabetes Institute's Australian Diabetes, Obesity and Lifestyle Study who provided information on their fruit and fruit juice intake through a food frequency questionnaire. They found participants who ate more whole fruits had 36 percent lower odds of having diabetes at five years. The researchers found an association between fruit intake and markers of insulin sensitivity, meaning that people who consumed more fruit had to produce less insulin to lower their blood glucose levels.
"This is important because high levels of circulating insulin (hyperinsulinemia) can damage blood vessels and are related not only to diabetes, but also to high blood pressure, obesity and heart disease," Bondonno said.
