Unlike ripe bananas, green bananas contain less sugar and are rich in resistant starch - a type of carbohydrate that can control blood sugar and improve gut health.
However, using green bananas properly is an important factor to optimize health benefits and control blood sugar.
Resistant starch in green bananas is not digested in the small intestine but is transported to the colon, where it becomes a food source for beneficial bacteria.
According to a study published in Nutrition Journal, resistant starch helps reduce the glycemic index (GI) and improve insulin sensitivity, thereby controlling blood sugar more effectively.
Green bananas slow down the digestion and absorption of carbohydrates, helping to prevent spikes in blood sugar after meals. A study from the Journal of Functional Foods found that consuming foods rich in resistant starch, such as green bananas, reduced blood glucose levels after meals.
Being overweight is a major risk factor for type 2 diabetes. Green bananas are low in calories and help promote feelings of fullness, thereby aiding in weight control.
Best ways to use green bananas:
Boiled green bananas
Boiled green bananas are a simple way to prepare them, preserving their nutritional value and removing some of the astringency.
Boiling green bananas does not increase blood sugar levels, so it is safe for diabetics. Eating boiled green bananas with green vegetables or steamed fish creates a balanced and nutritious meal.
Green banana powder
Green banana powder, made from dried and finely ground green bananas, is a good source of resistant starch. You can add green banana powder to plain yogurt or smoothies. Green banana powder helps improve fasting blood sugar in people with diabetes.
Green banana salad
Sliced green bananas mixed with vegetables, olive oil, and a little apple cider vinegar make a fiber-rich salad that aids digestion and controls blood sugar.
Grilled green bananas
Roasting green bananas without added sugar or fat can reduce the natural astringency, while retaining the resistant starch.
Important notes when using green bananas:
Don’t eat too much: Although green bananas are good for your health, consuming too much can cause bloating and indigestion due to their high starch content. A study from Diabetes Care recommends that diabetics should only eat 1-2 green bananas per day.
Combine with foods rich in protein or healthy fats: This helps stabilize blood sugar and reduce the GI of the meal.
Avoid fried green bananas: Cooking them in oil increases calories and reduces health benefits.
