Bitter Gourd
Bitter gourd, also known as bitter melon, can be helpful for controlling diabetes due to its blood glucose lowering effects. It tends to influence the glucose metabolism all over your body rather than a particular organ or tissue.
It helps increase pancreatic insulin secretion and prevents insulin resistance. Thus, bitter gourd is beneficial for both type 1 and type 2 diabetes. However, it cannot be used to entirely replace insulin treatment.
