Green banana is regarded as the darling of losing weight, because it contains resistant starch, and its glycemic index is lower than that of Huang Xiangjiao. Green banana helps to lose weight: resistant starch, medium glycemic index
Resistant starch has a satiety similar to dietary fiber, and can prevent glucose from entering the intestine, which helps to reduce and maintain the stability of blood sugar and prevent obesity caused by excessive eating. However, green bananas are rich in resistant starch, which set off a weight loss craze in Japan and Taiwan Province Province.
In addition, because green bananas contain maltodextrin, which is difficult to digest, and is not easily absorbed in the small intestine, and its function is similar to dietary fiber, it belongs to a food with a medium glycemic index, so the rising speed of blood sugar after eating is not as high as that of Huang Xiangjiao with a high glycemic index, which is one reason why it has become a good helper for weight control.
Green banana resistant starch needs to be refined and eaten directly, which is easy to constipation.
Jiang Shizhen, a nutritionist at Daqian General Hospital, said that mature Huang Xiangjiao has a laxative effect, but immature turquoise bananas contain more tannic acid, which is not only hard and astringent in taste, but also astringent to the digestive tract, which will inhibit gastrointestinal peristalsis, make the feces dry and hard, and make it easy to constipation or aggravate constipation symptoms if eaten too much.
