Kiwifruit has a relatively low glycemic impact on a per serving basis. DRRs from kiwifruit have a substantial capacity to retard mixing and glucose diffusion, even in the absence of the gut-soluble pectin fraction. If the ability of kiwifruit dietary fiber to reduce mixing extends to the gut lumen, where it may reduce mass transfer of digesta to the gut wall, and is augmented by an ability to reduce glucose diffusion, as the in vitro results suggest, it may have an important role to play in protecting against disorders related to absorption rate, such as the postprandial blood glucose excursion.

Such a conclusion is supported by the observation that the GI of kiwifruit measured in humans is less than is calculated from the glycemic indices of its constituent sugars alone. Further, expressing the relative glycemic impact of kiwifruit on the basis of customarily consumed portions reveals that the relative effect of kiwifruit on blood glucose levels will be very low, and it is therefore a healthy food option for consumers with impaired glucose tolerance.

獼猴桃每份的血糖影響相對較低。獼猴桃的DRR有很大的能力來延緩混合和葡萄糖擴散,即使在沒有腸道可溶果膠部分的情況下。如果獼猴桃膳食纖維減少混合的能力延伸到腸腔,在腸腔中它可能會減少消化液向腸壁的傳質,并通過減少葡萄糖擴散的能力得到增強,正如體外結果所表明的那樣,它可能在防止與吸收率相關的疾病方面發(fā)揮重要作用,例如餐后血糖漂移。

這種結論得到了以下觀察結果的支持:在人體內測量的獼猴桃的GI低于僅根據其組成糖的血糖指數(shù)計算得出的GI。此外,根據習慣食用部分表達獼猴桃的相對血糖影響表明,獼猴桃對血糖水平的相對影響將非常低,因此獼猴桃是糖耐量受損消費者的健康食品選擇。
