Constipation is a common clinical phenomenon, and most people have suffered from constipation at one time or another, especially the elderly over 60 years old. Elderly people are prone to constipation because of the relaxation of the colon, weakened contraction of the intestinal wall, reduced activity, reduced dietary fiber and water intake, and reduced digestive and excretory functions. Although constipation is not considered a major disease, it seriously affects the health and quality of life of the elderly population. Many elderly people rely excessively on laxatives in order to relieve constipation. In fact, taking laxatives can only relieve the urgent need, but cannot restore the bowel function, and may bring serious adverse reactions and dependence. To keep themselves away from constipation, constipated patients should consider regulating their diet, avoiding straining, strengthening exercise, and developing regular bowel habits as the main treatment means to help restore the physiology of defecation. Taking effective prevention and treatment countermeasures for functional constipation in the elderly is an important task that cannot be ignored to maintain the physical and mental health of the elderly. Dietary modifications “food treatment is better than medicine treatment”. Necessary dietary conditioning, a reasonable mix of dietary structure is the key to the treatment of constipation in old age. A reasonable diet can harmonize the balance of the internal and external environment of the body, keep the stool flowing smoothly, and also reduce the symptoms. Therefore, it is especially important for the dietary conditioning of elderly patients with constipation. 1, a reasonable dietary structure (1) eat more vegetables rich in fiber stool is composed of food residues and water, therefore, the formation of constipation and dietary components are closely related. Vegetables, fruits contain plant cellulose or pectin, in the intestinal tract after absorbing water expansion, in addition to softening the stool to increase the amount of feces, but also to promote the reproduction of parasitic bacteria in the intestinal tract, enhance the gastrointestinal motility function, play the role of laxative. Many foods rich in fiber, such as wheat bran, fresh bean pods, young corn, peanuts, spinach, garlic, potatoes, pumpkin, carrots, groundnuts, kelp, etc., meat to beef, especially red beef contains more muscle fiber. Daily can increase the amount of gas-producing vegetables such as potatoes, radishes, onions, soybeans, etc., of course, to avoid excessive exhaust, need to gradually increase. However, for the elderly with weak gastrointestinal function, fiber meals should not be consumed too much, one meal a day, otherwise it will increase the burden on the stomach and intestines, resulting in food can not be fully digested and absorbed, but also reduce the utilization of other nutrients, which may cause malnutrition. Of course, not all foods rich in dietary fiber have laxative effects, such as yam is warm, but eat more to aggravate constipation. (2) eat less or do not eat stimulating and spicy food spicy stimulating food such as white wine, yellow wine, chili, pepper, ginger, fennel, garlic, onion, etc., the rectal mucosa has a strong stimulating effect, making it congested edema, so that patients defecate when the anal opening burning pain. (3) moderate diet elderly people’s response to hunger decreased, so the amount of food significantly reduced, if too little food, can not produce effective gastrointestinal stimulation, so that the intestinal peristalsis slowed; at the same time, less food and less stool, the intestine can not be moderate filling, not up to the volume of stimulation response, can not trigger the cerebral cortex and nerve center regulation of the firing, feces can not be discharged in a timely manner, water absorption constantly caused by dry feces and difficult to discharge. Only by ensuring sufficient food intake and regulating their gastrointestinal functions can they stimulate intestinal peristalsis and improve the symptoms of constipation to a certain extent. Of course, the elderly have bad teeth and poor gastrointestinal function, try to eat fewer meals, eat some soft, easy to digest, nutrient-rich food, not too fine. (4) sufficient fat fatty foods can lubricate the intestinal tract, while fatty acids produced by the decomposition of fat can stimulate the intestinal smooth muscle and make intestinal peristalsis faster, favorable to defecation, of course, such foods should not eat too much. Such as walnuts, peanuts, sesame and other foods or peanut oil, sesame oil, sunflower oil, stewed fatty foods, etc., can lubricate the intestines, but can not eat more fried, fried, branded, baked food. (5) supply B vitamins B vitamin deficiency can lead to intestinal muscle weakness and thus cause constipation. Eat more B vitamin-rich food, such as coarse grains, yeast, sweet potatoes, potatoes, beans and soy products, etc., can promote the secretion of digestive juices, maintain and promote intestinal peristalsis, conducive to bowel movements.
