The purpose of this study was to examine how gold kiwifruit pericarp (pericarp is defined as the skin of the fruit) consumption and the timing thereof affect the postprandial blood glucose profile. The study was conducted on twelve healthy volunteers (six men and six women). According to our results, the simultaneous intake of gold kiwifruit with bread and the prior intake of gold kiwifruit evidently suppressed the postprandial blood glucose elevation compared with exclusive bread intake. There was no significant difference in postprandial blood glucose changes between the ingestion of gold kiwifruit pericarp and pulp and that of gold kiwifruit pulp only. The highest postprandial blood glucose elevation was suppressed by 27.6% and the area under the blood glucose elevation curve by 29.3%, even with the exclusive ingestion of gold kiwifruit pulp. We predicted that the ingestion of both the pericarp and pulp of gold kiwifruit would reduce the postprandial blood glucose elevation to a greater extent than that of gold kiwifruit pulp only; however, there was no significant difference between the two. These results indicate that gold kiwifruit consumption significantly suppresses the postprandial blood glucose elevation regardless of pericarp presence or absence and the timing of ingestion.
本研究旨在探讨食用金奇异果皮（果皮定义为果实的外皮）及其食用时间如何影响餐后血糖谱。该研究共纳入了 12 名健康志愿者（6 名男性和 6 名女性）。根据我们的研究结果，与单独摄入面包相比，同时摄入金奇异果和面包以及预先摄入金奇异果均可显著抑制餐后血糖升高。金奇异果皮与果肉同时摄入和仅摄入金奇异果果肉相比，餐后血糖变化无显著差异。即使仅摄入金奇异果果肉，也可使餐后血糖升高最高值降低 27.6%，血糖升高曲线下面积降低 29.3%。我们预测，同时摄入金奇异果皮和果肉将比仅摄入金奇异果果肉更能降低餐后血糖升高，但两者之间无显著差异。这些结果表明，无论是否存在果皮以及食用时间如何，金奇异果的摄入均能显著抑制餐后血糖升高。
