Are bananas fattening?

吃香蕉会胖吗?

Those who claim they are argue that bananas cause the body to make lots of insulin, and insulin causes fat growth.

那些声称香蕉使人发胖的人辩称香蕉促进人体分泌大量胰岛素，胰岛素会使人发胖。

How much insulin we produce is related to how fast a food becomes sugar in our bloodstream. How can you know if a food makes a lot of sugar quickly? The glycemic index (GI) rating tells us. Foods with GI scores above 75 are considered high-GI foods. Bananas have a GI of 62, which is considered low.

人体分泌多少胰岛素与食物在血液中转化成糖的快慢有关，那我们怎么能知道一种食物是否会很快转化成大量糖分呢?这个可以从血糖指数等级得知。血糖指数高于75的食物被认为是高血糖指数食物。香蕉血糖指数为62，数值较低。

Weight loss can be a struggle for anyone, but it is especially hard for diabetics. A study looked at how the starch from unripe bananas affected the weight of a group of obese 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 sensitivity from the banana diet.

对任何人来说，减肥都是一种挣扎，但对糖尿病人来说尤其困难。一项研究观测了未成熟香蕉中的淀粉如何影响肥胖糖尿病人的体重。糖尿病人每顿都吃很多香蕉，四周后他们明显比控制饮食的人体重下降更多。吃香蕉餐后，胰岛素敏感度也有所改善。
