升糖指数衡量的是某一特定食物提升血糖的快慢，而升糖负荷还考虑到了份量因素。

While the glycemic index measures how quickly a particular food raises blood sugar, the glycemic load takes portion sizes into account.

比如，西瓜虽然升糖指数很高，但它的升糖负荷较低，因为这种水果的绝大部分成分是水。

Hence a food like watermelon, with a high glycemic index, has a low glycemic load, since much of the fruit is water.
