许多轶事报告表明，猕猴桃（猕猴桃）有泻药的作用。这可能是一种可接受的膳食补充剂，特别是对于经常出现便秘的老年人。我们希望获得客观的证据来证明经常吃猕猴桃是否能促进老年人的通便。38名年龄在60岁至60岁之间的健康成年人在三周内保持正常饮食，每30公斤体重吃一个猕猴桃或不吃一个猕猴桃，然后是为期三周的交叉期。每日记录排便次数及大便特征。猕猴桃显著提高了这些成年人的通便率。经常食用猕猴桃似乎会导致大便更大、更软，以及更频繁地排便。猕猴桃作为一种自然疗法，对大多数人来说似乎是美味的，并为健康的老年人提供了改善的泻药。可能整个水果中有很多因素参与其中，但粪便的性质表明纤维很重要。这项研究为通过改变饮食来改善肠道功能、健康和幸福提供了证据。
Numerous anecdotal reports have suggested that kiwifruit (Actinidia deliciosa) has laxative effects. This could be an acceptable dietary supplement, especially for elderly people who often present with constipation. We wished to obtain objective evidence as to whether or not kiwifruit eaten regularly could promote laxation in elderly people. Thirty-eight healthy adults of age > 60 years consumed their normal diet, with or without one kiwifruit per 30 kg bodyweight for three weeks, followed by a 3-week crossover period. Daily records were taken on frequency of defecation and characteristics of the stools. Kiwifruit significantly enhanced all tested measures of laxation in these adults. The regular use of kiwifruit appeared to lead to a bulkier and softer stool, as well as more frequent stool production. Kiwifruit as a natural remedy appears palatable to most of the population and provides improved laxation for elderly individuals who are otherwise healthy. It is likely that a number of factors in the whole fruit are involved, but the nature of the stools suggest fibre is important. This study provides evidence of the potential for improvement in bowel function, health and well-being through changes in diet.
