Green bananas, rich in fiber, good for the gut and controlling blood sugar
Bananas are a familiar, nutritious fruit, but few people know that the health value of bananas changes significantly with maturity. From green bananas to yellow bananas, the conversion of starch into natural sugar not only affects the flavor but also affects digestion and blood sugar levels.
According to Ms. Lindsay Curtis - a health writer in the US, medically examined by Elizabeth Barnes, a nutritionist in the US, choosing green or ripe bananas depends on each person's health goals.
Green bananas contain high levels of resistant starch, a form of carbohydrate that acts similarly to fiber. This type of starch is not completely digested in the small intestine but goes down to the large intestine, nourishing beneficial bacteria and supporting the digestive system.
Nutrition expert Elizabeth Barnes - working at a clinical nutrition counseling system in the US, said: "Resistible starch in green bananas helps slow down digestion, increase feelings of fullness and support more stable blood sugar control.
Green bananas have a low glycemic index (GI), about 30, which helps blood sugar increase more slowly after eating. This is especially beneficial for people who need to control blood sugar or are at risk of diabetes.
Some studies also show that resistant starch can improve insulin sensitivity, helping the body use sugar more efficiently, thereby reducing the risk of metabolic disorders.
Golden bananas, easy to digest, rich in energy and antioxidants
When bananas are ripe, most resistant starch will be converted into natural sugars such as glucose, fructose and sucrose. This makes yellow bananas sweeter, softer and easier to digest.
Nutrition expert Elizabeth Barnes commented: "Cooked bananas are a fast source of energy, suitable for people who need recovery after exercise or immediate energy boost.
Yellow bananas also contain more antioxidants than green bananas. These compounds help protect cells from oxidative stress, contributing to reducing the risk of chronic diseases such as cardiovascular disease and cancer.
Although having a higher GI (about 51), ripe bananas are still considered safe for the majority of healthy people if eaten at a reasonable level. To limit rapid blood sugar spikes, experts recommend combining bananas with protein or healthy fats such as yogurt or nuts.
In general, both green and yellow bananas are beneficial for health. Green bananas are suitable for people who need to control blood sugar and improve digestion, while yellow bananas are suitable for quickly and easily absorbing energy. The choice of which type of banana should be based on each person's nutritional needs and physical condition.
