正常和非正常，如何解释这个例子？

当我在网上找＂正常人餐后会spike多高时＂，看到这么一个例子：

"Sorry, a bit of thread hi-hacking  I am a non-diabetic, bmi18-19, active female. My Fasting tests are around 70-80, so normal. OGTT, even with 75g of glucose only took me to a high of 115mg/dl, no spike or reactive hypo. But food gives me spikes from 175mg/dl for just 1 green banana, 210 mg/dl for 2 small slices of toast and butter, and up in the 230 mg/dl if I dare to have a pudding, even without the main course first ! First, is this normal? Second, why do these foods cause these spikes when 75g of pure glucose causes no rise at all, after all banana is only around 20-30g of carb, 2 slices of toast about the same."

按现代诊断标准，她肯定是非糖，非前糖，但如果食物对她的冲击这么大，那她的胰岛细胞是不是也受损厉害，久而久之也会。。。
