Kiwifruit are high in both soluble and insoluble fibers containing about 3.4 g fiber per 100 g fruit. Kiwifruit contain high lignin content, which contributes to their insoluble dietary fiber content. Kiwifruit have also been known for its beneficial effect on gut health and also for its strong laxative properties. Evidence suggests that increased solubilization of polymers occurs during ripening within the cell walls of kiwifruit, resulting in an enhanced ability to hold water. Several studies have demonstrated the usefulness of kiwifruit consumption in the treatment of constipation in healthy elderly persons. Actinidin, the proteolytic enzyme in kiwifruit, also enhances protein digestion in both the stomach and the small intestine in concert with the gastric and intestinal proteases. In another study, kiwifruit consumption significantly reduced the colon transit time in patients with irritable bowel syndrome. Kiwifruit has also been shown to be effective in treating iron deficiency. Significant improvement in iron status of young women with mild iron deficiency was noticed after consumption of gold kiwifruit along with an iron-fortified breakfast cereal. In a placebo-controlled crossover trial with 25 athletes, kiwifruit drink supplementation during athletic training was beneficial in maintaining blood glucose and mineral levels, with no significant effect on plasma insulin. Improvement in serum ferritin (nearly 50%) and hemoglobin concentrations was also noticed in women who consumed kiwifruit along with an iron-fortified breakfast. Aqueous extract of Gold kiwifruit also showed β-glucuronidase-inhibiting and β-glucosidase-promoting activity. Also, both gold and green kiwifruit extracts could promote the growth of fecal lactic acid bacteria and reduced the growth of E. coli.

猕猴桃的可溶性和不溶性纤维含量都很高，每100克水果中含有约3.4克纤维。猕猴桃含有高木质素含量，这有助于其不溶性膳食纤维含量。猕猴桃也因其对肠道健康的有益作用和强大的泻药特性而闻名。有证据表明，在猕猴桃细胞壁内的成熟过程中，聚合物的增溶作用增加，从而提高了保水能力。几项研究表明，食用猕猴桃对健康老年人的便秘有治疗作用。猕猴桃中的蛋白水解酶猕猴桃素也与胃蛋白酶和肠道蛋白酶一起促进胃和小肠中的蛋白质消化。在另一项研究中，食用猕猴桃显著缩短了肠易激综合征患者的结肠转运时间。猕猴桃也被证明对治疗缺铁症有效。轻度缺铁的年轻女性在食用金猕猴桃和铁强化早餐谷物后，铁状况显著改善。在一项有25名运动员参加的安慰剂对照交叉试验中，运动训练期间补充猕猴桃饮料有利于维持血糖和矿物质水平，对血浆胰岛素没有显著影响。食用猕猴桃和铁强化早餐的女性的血清铁蛋白（近50%）和血红蛋白浓度也有所改善。金猕猴桃水提取物也显示出β-葡萄糖醛酸酶抑制和β-葡萄糖苷酶促进活性。此外，金和绿色猕猴桃提取物都可以促进粪便乳酸菌的生长，并减少大肠杆菌的生长。
