The truth is that bananas can be included in a diabetic diet when eaten in the right portion and at the right stage of ripeness.

Health Benefits of Banana for Diabetics

Dietary fiber promotes gut health and helps prevent constipation, a common issue in people with diabetes.
4. Provides Quick Energy
In controlled portions, bananas provide natural energy without the need for processed sugary snacks.
5. Supports Nerve and Muscle Function
Vitamin B6 in bananas supports nerve health, which is especially important for people with long-standing diabetes.

- ½ small banana or 1 small banana (100–120 g) per day
Tips:
