When people get old, their physical function declines, so we should pay special attention to the intake of nutrition. Medical research shows that arteriosclerosis in middle-aged people is closely related to diet, so people should pay great attention to the type and quantity of diet when they reach middle age. Generally speaking, the reasonable intake of fish and meat should be 2: 1. Generally speaking, eating fish should be twice as much as eating meat, which is extremely beneficial to prevent arteriosclerosis in middle-aged people. There are a lot of fatty acids in meat at room temperature. If you take too much, the cholesterol in human blood will increase, which will lead to arteriosclerosis. Although fish also contains animal fat, fish oil contains more unsaturated fatty acids, which can effectively prevent arteriosclerosis. At the same time, fish oil also contains substances that promote blood circulation and inhibit blood coagulation and thrombosis. Therefore, the diet of middle-aged people should appropriately increase the intake of fish, which can effectively prevent the occurrence of cardiovascular diseases.

Pay attention to calcium supplementation

Although calcium is an indispensable mineral in a person's life, special attention should be paid to calcium supplementation after entering old age to prevent osteoporosis from causing diseases.

Foods containing more calcium include bean products, dairy products, dried shrimps, walnuts, Chinese cabbage and celery.

Vegetarian health care for the elderly

The elderly have less activities and consumption, and the functions of various organs in the body naturally decline. In this case, if you eat more protein-rich food, it will increase the burden on the digestive organs, produce indigestion, and gradually appear symptoms such as fullness in the chest and abdomen, belching, acid swallowing, stench, dreaminess at night, and even insomnia, irritability and diarrhea. After a long time, neurasthenia, dyspepsia, and serious stomach problems will become obvious aging after two or three years, and even blood pressure will rise, arteriosclerosis, cardiac labor disorders, cerebral vasospasm, coronary heart disease, and so on.

Modern medicine believes that. A young adult needs 50 ~ 100g protein every day, but the elderly can reduce it moderately. It is also for this reason that vegetarianism is advocated, because meat food is high in calories and difficult to digest and absorb. For an elderly person who doesn't exercise much, it is better to eat less.

When people are old, we should pay special attention to the structure and composition of diet. The body of the elderly is gradually aging from health. Muscle strength is gradually weakened, and the secretion of digestive glands is gradually reduced, so digestion is insufficient and incomplete. In addition, the material metabolism of the elderly is not as vigorous as that of teenagers, and their consumption is relatively reduced. Some metabolites are easy to accumulate, and cholesterol is one of them. Too high cholesterol is easy to deposit on the tube wall, causing vascular "atherosclerosis" lesions.

The serious consequence of vascular atherosclerosis is hypertension first. The digestive ability of the elderly is declining. It is also easy to cause constipation. A considerable number of elderly people are often constipated and often eat flour and rice. Too little food containing fibrous tissue will lead to this phenomenon.

Eating vegetarian food and vegetables for the elderly not only plays a positive role in preventing diseases such as heart disease, hypertension, diabetes, and intestinal cancer, but also plays a positive role in preventing aging and striving for longevity. This is because vegetarian food contains more vitamins C and E. Vitamin C can promote the absorption of oxygen by cells, promote the formation of these substrates, and is conducive to cell repair. It can also increase the formation of antibodies against bacteria. Vitamin E can also promote cell division, delay cell aging and prolong life.

Therefore, indifferent diet is indeed an indispensable aspect for middle-aged and elderly people to strive for health and longevity. Middle-aged and elderly people should eat coarse grains (such as corn, sorghum and sweet potato). ) and vegetables containing a lot of crude fiber (such as celery, rape, Chinese cabbage, sherbet, Chinese cabbage, radish and beans).
