相似的一项研究也证实了，当作为一顿饭的一部分食用时，芸豆在降低GI指数方面起着作用[11]。
一顿饭对血糖的影响不单单取决于主食的升糖效果，还包括我们吃的食物种类，食物种类越丰富，这一餐整体的升糖作用就更缓和。

糖尿病患者对豆类的消化速率影响GI值
糖尿病患者表现出胰岛素抵抗和胃排空延迟，这可能会影响血糖反应[13]。
因此，在多种因素的影响下，豆类的GI值会有波动。我们对豆类的制备方法、加工处理、烹饪方式等都会影响豆类GI值。那么，关于糖尿病患者如何吃豆类有哪些建议呢？
1. 选择豆类原型，尽量不选择去皮、磨粉、碾碎等减小豆粒的方式；
2. 发酵豆类或罐装豆类本身虽然对降低这一餐的血糖指数作用不大，但可以作为配菜食用，是很好的消化酶及维生素K2等营养素的来源；
3. 烹煮后，待冷却或冷藏后再回锅煮食，可降低豆类升糖指数；
4. 搭配其他食物一起吃，先吃肉菜类，再吃豆类。
我们不能因为豆类GI值有所波动而排斥它，相反，在膳食中添加豆类可以降低这一餐的总GI指数，有助于更好地控制餐后血糖。
总之，糖尿病患者重要的不是指着眼于某一类低升糖指数的食物，而是要注意均衡的饮食，才能更好地控制血糖。
最后，没有什么食物是糖友的绝对禁忌，只要聪明选择，正确地吃，多多积累经验，就能吃得美味又能控制好血糖。
