Foods that keep diabetes at bay

A diet rich in high-fibre foods – such as fruits, vegetables, legumes and whole grains – encourage the production of short-chain fatty acids that are beneficial for the immune system and may help protect against the onset of Type 1 diabetes, a study shows.

The findings showed that the western diet, which lacks dietary fibre, affects human gut microbiota and the production of short-chain fatty acids acetate or butyrate. The specialised diet uses starches – found in many foods including fruit and vegetables – that resist digestion and pass through to the colon or large bowel where they are broken down by microbiota (gut bacteria). This process of fermentation produces acetate and butyrate which, when combined, provided complete protection against Type 1 diabetes, the researchers said. “Our research found that eating a diet which encourages the gut bacteria that produce high levels of acetate or butyrate improves the integrity of the gut lining, which reduces pro-inflammatory factors and promote immune tolerance,” said Eliana Marino researcher at Monash University in Australia.

“We found this had an enormous impact on the development of Type 1 diabetes,” Marino added.
