食物血糖生成指数,英文简称为GI,指的是人体食用一定量食物后会引起多大的血糖反应。要测定食物的GI值,首先要找一组健康志愿者,在早晨空腹情况下,吃进含有50g碳水化合物的食物,然后每隔15～30分钟测定一次血糖,直到2个小时。以同一组人吃进50g葡萄糖后的血糖变化为100%,计算和比较出各种食物的GI值。一种食物的GI值至少有7个人进行同样的实验才能得出,因此,这是一个食物的生理学参数,比较
Food glycemic index, referred to as GI in English, refers to the human body after eating a certain amount of food will cause much blood sugar reaction. To determine the GI value of food, first of all, to find a group of healthy volunteers in the morning fasting, eat foods containing 50g carbohydrates, and then every 15 to 30 minutes measured blood glucose, until 2 hours. With the same group of people eating 50g glucose after the change of 100% blood sugar, calculate and compare the GI value of various foods. A food GI value of at least seven individuals to conduct the same experiment can be drawn, therefore, this is a physiological parameter of the food, compared
