 A new study has found that dietary sugar can cause insulin resistance in fruit flies, which is similar to the effect seen in humans with type 2 diabetes. The researchers fed the fruit flies a high sugar diet and observed that they became insulin resistant at higher levels of fat and showed signs of hypoglycemia. They also identified changes in gene expression related to lipid metabolism and insulin signaling, suggesting that these processes may play a role in the development of insulin resistance. This study provides evidence for a potential link between dietary sugar intake and insulin resistance, and could help scientists better understand the underlying causes of this disease.
