所谓高GI的食物,“Eating a lot of high GI foods can be detrimental to your health because it pushes your body to extremes. ”,吃进去血糖即刻大幅度升高,胰岛素相应大量释放,大量血糖转化成脂肪储存进身体;
所谓低GI的,“slowly trickle glucose into your blood stream keeps your energy levels balanced and means you will feel fuller for longer between meals”,能量在身体里面一点点释放,热量被匀速地使用,从而减少脂肪的形成和两餐之间饥饿感的产生。
