[Bring healthy health] Common health misunderstandings for the elderly

With the improvement of living standards, the elderly pay more and more attention to health care. However, due to various reasons, the elderly's cognition and grasp of health knowledge are far lower than the general population, and there are many misunderstandings in health care.

1. Calcium supplement

The ultraviolet rays in the sun can transform 7-dehydrogenation cholesterol in subcutaneous fat into vitamin D, promote the absorption of calcium in the human body, and prevent the occurrence of osteoporosis and osteoporosis. It is enough to let the face and hands be exposed in the sun every day in summer.

Misunderstanding: The more calcium supplement, the better. The amount of calcium that can be absorbed by our bodies is limited. The absorption and digestive capacity of the elderly is also limited. Too much calcium supplementation, and the intestine cannot be absorbed and used in time. It may also cause the problem of bladder stones and constipation. Calcium supplementation of the elderly should adopt the principle of gradual steps, a small amount, so as to improve the absorption rate and physical utilization of the intestine.

Second, cholesterol intake

Cholesterol is a substance that is very needed physiological. Most of the cholesterol in the human body is synthesized by itself, only 20%is in vitro intake, and the intake of cholesterol does not depend on the amount of cholesterol itself, but depends on the content of fat in food.

Misunderstanding: Do not eat eggs. There are more cholesterol contained in egg yolks, but there are many nutrients that are very good for the human body in the egg yolk, especially lecithin. Although the cholesterol content in eggs is high (a egg contains about 300 mg of cholesterol), it also contains many necessary nutrients for the human body, such as high -quality protein, multiple vitamins, minerals, and also contains lecithin with important physiological functions Essence The lecithin contains the raw materials of synthetic nerve activity to transmit substances, which has an important role in maintaining memory, thinking, and analysis ability, and these important abilities are exactly what middle -aged and elderly people need. Eating one egg every day does not aggravate the metabolism burden.

Third, fat intake

Fat is one of the three major nutrients tied with sugar and protein. The proportion of fat supply heat accounts for 35-50%of the total calories, which is an important source of energy.

Misunderstanding: Dare to eat fat. Eating high -fat food for a long time is easy to get cardiovascular and cerebrovascular diseases, but it is not good for health to not eat a little fat. Animal fat contains lipoprotein, which can prevent cardiovascular disease. Animal fat is rich in vitamins, such as vitamin A, B2, B6, B1, E, and brain development. Get fat.

Fourth, physical exercise

The elderly often perform physical exercise, which can not only improve cardiopulmonary function, regulate emotions, but also prevent dementia and osteoporosis. It has a positive effect on improving the quality of life of the elderly.

Misunderstanding 1: The more you exercise, the better the calcium supplement. Although exercise helps the absorption of calcium, excessive exercise, calcium will be lost faster, and the knee joint is also prone to injury. It is recommended to take 5000-6000 steps a day. It can not only promote the absorption of calcium, and it will not easily hurt the joints. It can also reduce the risk of falling.

Misunderstanding 2: Morning exercise. In the morning, the oxygen content in the air is relatively small, especially in the park green space and other areas. Because the plant only oxygen after the photosynthesis, it is the same as people at night, absorbing oxygen discharge of carbon dioxide. In addition, low temperature can also increase emergencies. Exercise requires appropriate energy. The source of human energy is mainly sugar, fat, and protein in the diet. When the morning exercise can be performed on an empty stomach, the free fatty acid in the blood will increase significantly. Essence 3-5 pm is the time for the elderly to exercise.

Therefore, the health care of the elderly is essential, and it also needs scientific guidance. Excessive exercise will only be counterproductive and accelerate the development of various diseases. Only by performing scientific methods can we truly achieve the purpose of healthy aging.
