What is high fiber food?
There are two definitions of dietary fiber:

1. Physiologically, dietary fiber is defined as the residue of undigested vesicles in the digestive system of mammals, including cellulose, hemicellulose, pectin, gum, resistant starch and lignin.

2. From the chemical point of view, dietary fiber is defined as plant non-starch polysaccharide plus lignin.

High-fiber foods are mainly foods with high dietary fiber content, which mainly exist in plant foods in nature:

1, cereal. Don't process grains that are too fine. The finer they are, the more dietary fiber is lost. Buckwheat, millet, oats, sorghum, black rice, etc.

2. beans. All kinds of food. Soybean, mung bean, cowpea, adzuki bean, pea, broad bean, kidney bean, lentil, etc.

3. potatoes. Potatoes, sweet potatoes and other potatoes

4. vegetables. Vegetable fiber is more beneficial to human body than grain fiber, such as bamboo shoots, eggplant, peppers, bracken, cauliflower, spinach, pumpkin, Chinese cabbage, rape and so on.

5, fruit. The most cellulose content in fruits is dried red fruits, and the cellulose content is close to 50%, followed by dried mulberries, cherries, wild jujubes, dates, pomegranates, apples and pears. You can choose varieties with low sweetness and high fiber, such as apples, tomatoes and guavas. And avoid choosing fruits with high sweetness and delicious taste.

6. fungi. Fungi (dry) have the highest cellulose content, namely dried Lentinus edodes (31.6g100g), dried tremella fuciformis (30.4g/ 100g) and auricularia auricula (29.9g/ 100g).
