(1) Eat regularly and quantitatively to avoid overeating. The elderly have decreased activity, poor digestive function, decreased gastrointestinal muscle tension and decreased gastric juice secretion. Eating too much, especially overeating, will cause indigestion; Eating too much will make the abdomen swell and the diaphragm rise, which will limit the cardiopulmonary activity, increase the burden of cardiopulmonary, and aggravate the condition of patients with emphysema, cor pulmonale or coronary heart disease. Eating should not only be quantitative, but also regular, so that the metabolic activities of the gastrointestinal tract and even the whole body can be balanced, which is necessary to maintain health.
(2) Chew slowly to facilitate digestion and absorption. Chewing food carefully while eating is beneficial to the digestion of food. The salivary glands in the oral cavity can produce about 65,438+0,500 ml of saliva every day, which not only lubricates food and is beneficial to swallowing and cleaning the oral cavity, but also contains "salivary amylase", which can decompose starch in food into maltose and is beneficial to gastrointestinal absorption; Moreover, while chewing, gastric juice and pancreatic juice can be secreted due to reflection, which is beneficial to the further digestion and absorption of food.
(3) the diet should be diversified and not partial eclipse. The human body's demand for nutrients is varied, and the content of diet should also be varied. Elderly people with chronic diseases can adjust their diet according to the doctor's advice, but they can't simply choose between preferences and tastes. Unreasonable diet is harmful to their health.
(4) It is not advisable to eat very dry and hot food. The saliva secretion of the elderly is reduced, and the oral mucosal resistance is reduced, so it is not suitable to eat very hot and dry food. You can often eat some foods such as soup and puree, which is not only beneficial to digestion, but also can supplement some water and nutrition.
(5) Walking after meals is good for digestion. It is good for your health to take a little exercise and relax after meals, so that your stomach can have enough blood to digest food. As the saying goes, "Walk a hundred paces after a meal and live to ninety-nine", that's what it means. But you can't do strenuous exercise after meals, because the digestion and absorption of gastrointestinal tract after meals is the most laborious, so you need more blood supply and secrete enough digestive juice to digest food. At this time, if you take part in sports and overuse your brain, a lot of blood will be concentrated in various sports organs or brains, and the blood supply in the stomach will inevitably decrease, the secretion function of digestive juice will be hindered, and the absorption of food in the gastrointestinal tract will not be normal, which will lead to indigestion.
