Tho who claim bananas are fattening argue that bananas cau the body to make lots of insulin(胰岛素), and insulin caus fat growth.
How much insulin we produce is related to how fast food becomes sugar in our bloodstream. How can you know if food makes a lot of sugar quickly? The glycemic index(血糖指数), or GI rating tells us. Foods with GI scores above 75 are considered highGI foods, leading to faster sugar development. Bananas have a GI of 62, which is considered low.
Weight loss can be a struggle for anyone, but it is especially hard for diabetics(糖尿病患者). A study looked at how the starch from unripe bananas affected the weight of a group of
obe diabetics. After four weeks of a diet high in bananas, diabetics lost significantly more weight than on a control diet. They also saw improvements in insulin nsitivity from the banana diet.
What’s more, bananas have been shown to cut risks of strokes, diabetes and cancers.(Bananas are the most powerful fruit for lowering the risk of kidney cancer.) Bananas are also a rich source of fiber, which has been shown to help weight loss. Bananas that still have some green on the skin are even higher in fiber.
Skins from green bananas can be taken and, after removing the stem and dark tip, cut into small pieces 2－3 inches long and 1/2 inch wide. The pieces can be made into a tea or added to a dish. When you eat the skins, be sure you are eating organic bananas. The flesh of regular bananas is low in pesticides, but the skins are not.
