Dietary fiber is a "many-faced" person who maintains the body's gastrointestinal health. It has many physical and chemical properties and physiological functions. Including a certain degree of water capacity, can increase the volume and weight of the feces; with bacterial fermentation. Increase the beneficial bacteria in the intestinal tract; there is a certain viscosity, which can reduce the increase in postprandial blood glucose. Dietary fiber includes both soluble and insoluble dietary fiber, the former being more effective in protecting the health of the gastrointestinal tract.
Perfect functional soluble waxy fiber mainly refers to pectin, gum, etc. It can produce short-chain fatty acids after colonic bacterial glycolysis, providing 70% of the energy needed for colonic mucosa, and can regulate nervous system function, balance hormone levels, and stimulation. Digestive enzyme secretion and so on. In addition, it can also directly dilate blood vessels. Promote colonic blood circulation. The result of these combined actions is to maintain the normal structure and function of the gastrointestinal tract. If dietary fiber is absent from the diet, it can cause structural damage and dysfunction of the gastrointestinal tract and increase the risk of the onset of certain diseases such as ulcerative colitis.
Balanced flora There are many bacteria in the human intestine and they are relatively constant. Under normal circumstances. These bacteria are beneficial, they can inhibit the growth of certain pathogens such as Salmonella, Vibrio cholera, etc. Can also synthesize B vitamins and vitamin K. It is an important source of human vitamins. Soluble dietary fiber has a large amount of water, which provides an ideal site of hyperplasia for the intestinal flora, increasing the number of intestinal bacteria, but when the bacteria in the intestine overproliferate, dietary fiber can accelerate the bowel movements by accelerating Effluent, thereby maintaining the homeostasis of intestinal flora. In addition. Dietary fiber is also involved in maintaining the integrity of the intestinal mucosa. It can prevent bacteria in the intestines from moving through the wall of the intestine and cause illness, thereby effectively protecting the human body.
Prevention and treatment of constipation According to the survey, 20% to 30% of elderly persons over the age of 65 have constipation, among which the female incidence rate is particularly high. Long-term constipation is harmful to the human body and can cause complications such as rectal prolapse, sigmoid colon torsion, intestinal obstruction, and urinary retention. The reasons for constipation are very complicated, but a considerable part of it is caused by poor living habits. The lack of dietary fiber in the diet is one of the important reasons. Dietary fiber in food absorbs water in the intestine to fully expand, and promote the effective peristalsis of intestinal wall, so that intestinal contents quickly pass through the intestines and excreted from the body, objectively played a role in laxative. Dietary fiber preparations are bulky laxatives and have a mild nature. They have good curative effect on people with inadequate dietary fiber intake, can take long-term use without drug resistance, and have few side effects.
Clear "toxic" row "waste" dietary fiber in the role of prevention and treatment of constipation at the same time. Can help the body remove intestinal toxic substances. Various enzymes produced by bacteria in the intestine can break down food residues and produce some toxic substances. This is a normal physiological phenomenon. If the protein is broken down by bacteria. Can produce odor of cesium, amines, ammonia, hydrogen sulfide, etc., in the normal circumstances is a small amount of human absorption into the blood, can be transformed in the liver, detoxification, no effect on health. but. Such as long-term constipation. It can make a large number of toxic substances accumulated in the human body, beyond the liver detoxification ability, this time will cause chronic poisoning symptoms, such as bitter taste, bad breath, nausea, abdominal pain, abdominal distension, etc., the patient's face with pigmentation, mental euphemism, insomnia, Body aches. Affect life, work quality and social activities. Dietary fiber acts as a scavenger in the intestine. It absorbs, dilutes, and encapsulates various toxins and prompts them to be quickly excreted.
Prevention of Colorectal Cancer Colorectal cancer is the result of a combination of environmental, dietary habits, and genetic factors. Carcinogens can play a catalytic role, and dietary fiber is mainly through the removal of intestinal carcinogens to prevent the occurrence of colorectal cancer. In fact. There are often carcinogenic substances in the human intestinal tract, some of which are endogenous, such as nitrous acid produced by bacteria in the large intestine, bile acid in the metabolism of bile acids, etc.: Some are exogenous and enter the body with the diet, such as bakingç‚™ Or fish, fish and meat products produced by heterocyclic compounds. The number of these carcinogens is small and the concentration is low. It is not enough to cause cancer, but if the carcinogens accumulate in the intestinal tract for a long period of time, the risk increases greatly. Dietary fiber can reduce the chance of carcinogens coming into contact with the intestinal wall and prompt it to be excreted quickly. In addition, the dietary fiber can increase acidity in the intestinal tract through fermentation, or prevent colorectal cancer by changing bile acid metabolism.
