Foods with ribs contain dietary fiber? Don't fall into the "fibre" misunderstanding

Original title: Foods with ribs contain dietary fiber? Don't fall into the "fibre"
some people in order to supplement dietary fiber, will eat a lot of cold celery every day. Because celery tastes rough, they feel that celery contains more dietary fiber, while cold mixed to eat, because of fear of heating or chopping to destroy its dietary fiber. So, is it the taste of rough, with "hamstring" food to have dietary fiber? Will cutting vegetables and heating destroy dietary fiber?
In an interview with People's Daily China, Yan Guangfeng, director of the business department of the Science and Technology Information Exchange Center, said that dietary fiber is a class of carbohydrate polymers composed of food-eating plant cell wall residues and related substances, which cannot be digested by human digestive enzymes. Dietary fiber includes water-soluble dietary fiber and insoluble dietary fiber.
then, is it the taste of rough, with "hamstring" food to have dietary fiber? This is not the case. Yan Guangfeng explained that people's subjective feelings about dietary fiber are mostly affected by the word "fibre", the feeling of celery in the "hamstring" is dietary fiber. In fact, celery's "ribs" are the structure of the tube bundle in plant tissue, which is not the same as dietary fiber. Some taste not rough food, such as tender peas, beans, black beans and other beans, although cooked after the texture is delicate, soft taste, but the content of dietary fiber is much higher than the celery. Some vegetables that do not have obvious "ribs", such as leeks, orchids, spinach and other vegetables, also have higher dietary fiber content than celery.
a lot of people say that cutting vegetables and heating will destroy dietary fiber, is it true?" In fact, this is completely worrying. Cutting vegetables does cut off the tube structure in vegetables, but it doesn't destroy dietary fiber. Moreover, the nature of dietary fiber is very stable, daily cooking heating is not enough to destroy its structure, can not change its physiological characteristics.
Finally, He cautions that while dietary fiber has many benefits, such as regulating the intestinal bacterium, relieving constipation, regulating blood sugar, and preventing cardiovascular disease, it is not enough to overdose, especially in special groups, such as those suffering from malnutrition, gastrointestinal diseases or gastrointestinal surgery, as well as those suffering from old age constipation.
