多数水果血糖指数低
●GI≤55为低GI,这个食物消化慢、转化为葡萄糖的速度慢、血糖升高慢。
● 55~70之间为中GI食物。
● ≥70为高GI食物,消化快、转化为葡萄糖的速度快、血糖升高快。
我整理了一份常吃水果的血糖指数表,大家可以看一下。

可以看到,多数水果的GI值在55以下,属于低血糖指数水果。「血糖负荷」要注意
●≥ 20 为高血糖负荷食物,这样的食物对血糖影响大。
●11-19为中血糖负荷食物。
●≤ 10 为低血糖负荷食物,这样的食物对血糖影响较小。

有些水果,虽然是低GI食物,但是含糖量比较高,比如榴莲、波罗蜜、芭蕉、释迦,成了中高血糖负荷食物。很多人水果没吃够
分享这份资料,不是让大家从今以后只吃低糖水果、或者低GI水果;或者,看到高糖高GI水果就拉黑、不吃
高GI、高糖的水果,适量少吃并通过合理搭配也能帮助维持血糖稳态;反之亦然,低GI食物吃的过多,也会加重餐后血糖负担。
其实,很多人的问题是水果没吃够。

《中国居民膳食指南》建议每天要吃200-350g新鲜水果,果汁不能代替新鲜水果。
但实际上根据《中国居民膳食指南科学研究报告2021》,吃水果比较多的城市居民也只有55.7 克/天,远低于推荐标准。
已经很多研究证明,适当多吃水果有助于预防包括2型糖尿病、心血管疾病在内的多种慢性病。
