Jamun contains jamboline and jambosine, compounds that help slow down the conversion of starch into sugar, thereby regulating blood glucose levels. 

Regular consumption of Jamun may enhance the body's sensitivity to insulin, which is essential for type 2 diabetics.

With a low glycemic index, Jamun causes a slower rise in blood sugar compared to high-GI fruits, making it a safer fruit option for diabetics.

The fruit is packed with antioxidants like anthocyanins that protect pancreatic beta cells, potentially improving insulin production.

One of the common symptoms of diabetes is frequent urination. Jamun helps in reducing this issue due to its astringent properties.

Jamun is rich in fibre and helps regulate bowel movements, reducing the risk of constipation, which is often a concern in diabetics.

Being low in calories and high in fibre, Jamun helps promote satiety and supports weight control, which is crucial in managing diabetes.
