A June 2021 study by Edith Cowan University said,
"We found an association between fruit intake and markers of insulin sensitivity, suggesting 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.
"A healthy diet and lifestyle, which includes the consumption of whole fruits, is a great strategy to lower your risk of developing type 2 diabetes."
"Higher insulin sensitivity and a lower risk of diabetes was only observed for people who consumed whole fruit, not fruit juice,"
"This is likely because juice tends to be much higher in sugar and lower in fibre."
"As well as being high in vitamins and minerals, fruits are a great source of phytochemicals which may increase insulin sensitivity, and fibre which helps regulate the release of sugar into the blood and also helps people feel fuller for longer," she said.
"Furthermore, most fruits typically have a low glycaemic index, which means the fruit's sugar is digested and absorbed into the body more slowly."
