纤维素是植物细胞壁的主要组成部分,如谷糖、麸皮等主要就是由纤维素组成的,豆类、蔬菜和水果中纤维素含量也很丰富。这些食物提供的纤维素对人体健康有很重要的作用。 一、食物纤维素能促进肠的蠕动,利于肠道排空。以高蛋白、高脂肪等精细食物为主食,不吃或很少吃食物纤维素的人容易发生便秘,并可能诱发结肠癌。含纤维素较多的食物,进入大肠内能被肠内细菌有选择地分解发酵,从而促进好气菌的大量增殖,同时刺激肠道粘膜,加快新陈代谢,使肠道功能保持正常。
Cellulose is the main component of plant cell wall, such as gluten, bran and other mainly composed of cellulose, beans, vegetables and fruits in the cellulose content is also very rich. The cellulose that these foods provide has a very important effect on human health. First, food cellulose can promote intestinal peristalsis, conducive to intestinal emptying. High protein, high fat and other fine foods as the staple food, eat or eat less food-prone people prone to constipation, and may induce colon cancer. More food containing cellulose, enter the large intestine can be selectively decomposed fermented by the intestine bacteria, thereby promoting the proliferation of aerobic bacteria, while stimulating the intestinal mucosa, speed up the metabolism, to maintain normal intestinal function.
