Recent studies reveal jackfruit’s promising role in managing type 2 diabetes. One study demonstrated that incorporating jackfruit flour into the diets of individuals with type 2 diabetes significantly improved markers of blood sugar control, including reductions in HbA1c as well as both fasting and postprandial glucose. This result indicates that jackfruit flour could serve as an effective component of medical nutrition therapy for diabetes.

Another investigation focused on the blood sugar-lowering properties of jackfruit seeds. This study used animal models to show that jackfruit seed extract could significantly reduce blood glucose levels and possibly enhance the effects of diabetes medications. (Our view on the use of animals in medical research is here.)

Even jackfruit leaves may have medicinal qualities. In Indian Ayurveda tradition, consuming hot water extracts of (jackfruit) kathal leaves is said to help treat type 2 diabetes.

Collectively, these studies and traditional uses suggest that different parts of the jackfruit — be it the flour, seeds, or leaves — could be beneficial in the dietary management of diabetes.
