Kiwifruit are high in both soluble and insoluble fibers 獼猴桃富含纖維素 有潤腸通便的作用

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.

獼猴桃的可溶性和不溶性纖維含量都很高，每100克水果中含有約3.4克纖維。獼猴桃含有高木質(zhì)素含量，這有助于其不溶性膳食纖維含量。獼猴桃也因其對腸道健康的有益作用和強大的瀉藥特性而聞名。有證據(jù)表明，在獼猴桃細胞壁內(nèi)的成熟過程中，聚合物的增溶作用增加，從而提高了保水能力。幾項研究表明，食用獼猴桃對健康老年人的便秘有治療作用。獼猴桃中的蛋白水解酶獼猴桃素也與胃蛋白酶和腸道蛋白酶一起促進胃和小腸中的蛋白質(zhì)消化。在另一項研究中，食用獼猴桃顯著縮短了腸易激綜合征患者的結(jié)腸轉(zhuǎn)運時間。獼猴桃也被證明對治療缺鐵癥有效。輕度缺鐵的年輕女性在食用金獼猴桃和鐵強化早餐谷物后，鐵狀況顯著改善。在一項有25名運動員參加的安慰劑對照交叉試驗中，運動訓練期間補充獼猴桃飲料有利于維持血糖和礦物質(zhì)水平，對血漿胰島素沒有顯著影響。食用獼猴桃和鐵強化早餐的女性的血清鐵蛋白（近50%）和血紅蛋白濃度也有所改善。金獼猴桃水提取物也顯示出β-葡萄糖醛酸酶抑制和β-葡萄糖苷酶促進活性。此外，金和綠色獼猴桃提取物都可以促進糞便乳酸菌的生長，并減少大腸桿菌的生長。
