Bananas are high in fiber and low in calories. Studies have shown that there is a link between higher fiber intake and lower body weight. This nutrition also helps to lower and stabilize blood sugar levels. Bananas are an excellent source of fiber. A medium-sized banana contains 3.07 grams of fiber, which can help people feel full for a long time and reduce the total calorie intake. It takes a long time for the human body to digest certain types of fiber, so that it can better regulate the food intake.
Fiber can also help lower cholesterol levels and reduce the risk of heart disease. Immature green bananas contain resistant starch. Resistant starch is a kind of carbohydrate, which is not easy to decompose in small intestine. Instead, it passes through the large intestine, which means that it does not increase blood sugar levels. Then it will ferment in the large intestine to stimulate the growth of beneficial bacteria in the intestine. Eating more resistant starch can help people lose weight because its function is similar to dietary fiber. It may make a person full for a long time, thus reducing appetite. Studies have shown that resistant starch can also help improve insulin sensitivity. It is beneficial to intestinal health, and can also help solve constipation and reduce the risk of colon cancer.
Bananas are healthy and nutritious, no doubt. They are also rich in fiber, but low in calories. Compared with other high-carbohydrate foods, most bananas have a low glycemic index, so they will not lead to a significant increase in blood sugar levels. Although there is no direct study on the effect of bananas on weight, bananas do have some characteristics, which should make them weight-loss friendly foods. If you want to lose weight, there is absolutely nothing wrong with bananas as part of a balanced diet.
