高脂肪、低膳食纤维饮食,是大肠癌高发的重要危险因素。让纤维素刷刷你的肠道膳食纤维被营养学家称为“没有营养”的营养,因为它的作用是其他营养素所无法替代的。缺乏膳食纤维,粪便在肠道内停留时间会延长,造成肠道对废物再次吸收,导致粪便中的致癌物长时间刺激肠壁。因此。纤维素被称为肠道的清洁工,它就像一把小刷子一样,促进肠道蠕动,清洗肠道内的垃圾和废物。减少肠道致癌物的停留时间,从而降低大肠癌的发病危险。美国防癌协会推荐每人每天摄食30—40克膳食纤维;日本70岁以下每天标准摄入量是19～27克:我国推荐的标准是每日膳食纤维30克。玉米、小米、大麦、小麦皮(米糠)和麦粉(黑面包的材料)等杂粮食物纤维含量较多:苹果、香蕉、芹菜、番茄、胡萝卜、四季豆、豌豆、薯类等也是纤维素的高能食品。红薯之所以被称为抗癌食品的冠军菜,正是这个道理。
High fat, low dietary fiber diet, is an important risk factor for the high incidence of colorectal cancer. Letting cellulose brush your gut dietary fiber is what nutritionists call “nourishing nutrition,” because its effect is irreplaceable with other nutrients. Lack of dietary fiber, fecal retention time in the intestine will be extended, causing the intestinal reabsorption of waste, resulting in long-term irritation of the colon in the stool. therefore. Cellulose, known as the gut cleaner, acts like a small brush to promote bowel movements and clean the gut of trash and waste. Reduce the residence time of intestinal carcinogens, thereby reducing the risk of colorectal cancer. American Association for the Prevention of Cancer recommends eating 30-40 grams of dietary fiber per person per day; Japan under the age of 70 standard daily intake of 19 to 27 grams: China’s recommended standard daily dietary fiber 30 grams. Corn, millet, barley, wheat bran (bran) and wheat flour (black bread material) and other grains are more fiber-rich foods: apple, banana, celery, tomato, carrot, green beans, peas, food. The reason why sweet potato is called the champion food of anti-cancer food is exactly the truth.
