It is generally calculated to ensure that diabetic patient is eating proper food. Normally, the 55 GI index is considered a low sugar level. Banana contains nearly 51 GI, which is lower than the minimum lowest GI. Hence, we can say that bananas can be eaten in type-2 diabetes. However, the quantity should be less in this case.

If you want to calculate the amount of sugar level in a food product, glycemic load is a more specific index. It calculates the amount of sugar present in your food. Normally, 10 glycemic loads are considered okay for type-2 diabetes. In the case of bananas, the glycemic load is about 11 to 14, which can be considered quite moderate. It may exceed the limit of low glycemic load but can be considered once or twice a week. The glycemic index and glycemic load both contribute to controlling the amount of intake of sugar in the body. It is extremely helpful for type-2 diabetic patients.

What is Resistant Starch?

Resistant starch is a type of carbohydrate. The body cannot digest this resistant starch. Hence, it reaches the colon in its original form. By reaching there, it works like fiber and feeds the good bacteria of the digestive system. Thus, it increases the number of good bacteria in the body and ultimately helps indigestion. 

The presence of resistant starch varies when the banana starts ripening. Normally, the content of resistant starch is higher in unripe bananas. Its quantity starts decreasing when the banana starts ripening. As the banana ripens, the sugar content in it starts increasing. This sugar content is produced by resistant starch. 

If the resistant starch is not completely absorbed in the body, then it gets converted into fat and absorbed in the body. Thus, even if we are eating a raw banana, it is not going to help us to lose weight.
