Fruit: Red dried fruit is the most abundant, and the cellulose content is close to 50%, followed by dried mulberry, cherry, wild jujube, black jujube, jujube, pomegranate, apple and pear.
The function of dietary fiber: absorbing water in intestine can dilute intestinal contents, reduce bile concentration and promote the growth and reproduction of normal resident bacteria in intestine; E. coli in the intestine can use cellulose to synthesize indispensable life substances such as pantothenic acid, nicotinic acid and riboflavin.
Foods rich in dietary fiber can also prevent constipation. Food fiber has a large volume, which can promote intestinal peristalsis, and the water in it is not easily absorbed, so it has a laxative effect.
Protect the skin. When the blood contains toxic substances, the skin becomes a place where it abandons waste. Facial acne is formed because there are too many acidic substances and saturated fat in the blood. The skin color of people who are often constipated is yellow, which is also because the feces stay in the intestine for too long, and toxic substances are absorbed through the intestinal wall, which makes the blood contaminated with toxins.
People who smoke too much look like ashes, which is also caused by the above reasons. Dietary fiber can stimulate intestinal peristalsis, make waste excreted in time, and reduce the toxic effect of toxins on intestinal wall, thus protecting the skin.
