First of all, the basal metabolic rate of the body decreases (basal metabolism refers to the minimum energy required by various organs of the human body to maintain life. ), although the food intake has not increased, people are getting fatter and fatter, commonly known as "obesity", which increases the risk of metabolic diseases.

In addition, compared with young people, the digestive ability and cardiovascular function of middle-aged men have also dropped a lot; Coupled with the pressure of life, often busy with work, irregular diet, accelerated the aging and degradation of the human body.

After the age of 50, a large number of men will usher in their own menopause, and their basal metabolism will further deteriorate. Coupled with the violent fluctuation of sex hormones secreted by testis, it will continue to decrease, and the absorption capacity of calcium in human gastrointestinal tract will be weakened, and calcium loss will be serious during metabolism, which will severely challenge bone health.

Therefore, after men enter middle age (after 80' s and 70' s), they should have health care consciousness, improve the metabolic function of human body and delay the aging speed.

Men over 40 should control their diet.

The first is that "three meals" should be quantified as often as possible.

The more regular the diet, the more conducive to digestion and absorption of the stomach, and also conducive to the stability of blood sugar. The more regular the metabolism of the liver and pancreas, the better the basic metabolism of the human body can be maintained.

Because there are many social engagements in business, most diets are messy, so it seems simple, but for many people, it is still very difficult to really do it.

Avoid overeating

I often hear some men say, "One meal can last a day." Show off as a skill. In fact, this is very harmful to the human body.

Overeating can easily lead to obesity and is not conducive to the stability of blood sugar.

Under normal circumstances, blood sugar will continue to rise after meals 1 hour, and then it will begin to decline after 2 hours. Three hours after meals, blood sugar can basically return to normal.

When people get old, the control function of the pancreas decreases, and hyperglycemia is prone to occur. If you overeat frequently, it will easily lead to uncontrolled blood sugar, so you should develop good eating habits.

In addition to avoiding overeating, we should also pay attention to chewing slowly, eating less sweets and avoiding drinking.

Eat a balanced diet

In view of the demand for balanced nutrition, it is recommended to eat at least 12 different foods every day and at least 32 kinds every week (Japanese nutritionists recommend eating at least 30 kinds every day). Can be simply divided into four categories:

First of all, the staple food: the main nutritional component of staple food is starch (digestible polysaccharide), which is the main source of our energy.

Including rice, pasta and some miscellaneous grains (corn, millet, sorghum, buckwheat and barley); There are also some beans (soybeans, mung beans, black beans, red beans and lentils); It also includes some potatoes (such as sweet potato, sweet potato, potato and yam).

Followed by meat food: such as livestock meat, poultry meat, fish, shrimp and crabs, shellfish including eggs and milk. This kind of food is rich in protein and fat and belongs to high-energy nutritious food. It is the source of protein, fat, various minerals and fat-soluble vitamins.

The third is vegetables: including green leafy vegetables and some melons and fruits; Such as spinach, cabbage, radish, lettuce, rape, tomato, cucumber, eggplant, bitter gourd, towel gourd and so on. There are many examples.

This kind of food is an important source of cellulose, vitamins and various minerals needed by human body.

The Dietary Guide for China Residents (20 16) suggests that ancient Chinese residents should eat 300-500g of fresh vegetables every day.

The fourth is fruit: such as oranges, grapefruit, apples, jujubes, strawberries, glucose and so on. This kind of food is rich in water, fructose and dietary fiber, so it is also very important for human health.

Most men prefer meat food, which easily leads to excessive fat intake and insufficient dietary fiber intake, so they often say that they should eat more vegetables and less meat.

Men over 50 years old can be exempted from three things.

1, stay up late

After the age of 50, the compensatory function of human body declines. Staying up late will disrupt the original biological clock of the human body, and the functions of various organs of the human body will decline because of staying up late, thus accelerating the aging of the human body.

Suggestion: It is best not to sleep later than 1 1 o'clock every night, and the ideal time is 9 9- 10/o'clock.

2. Smoking and drinking

As we all know, smoking and drinking are harmful to health.

Most post-50 s men still bear important responsibilities in society, so sometimes it is inevitable to smoke and drink for entertainment, and it is unreasonable not to touch them at all, so try to control them.

3. Husband and wife are not harmonious

When people reach middle age, both husband and wife may be experiencing menopause, and their physiological reactions are relatively large. They often quarrel over trivial matters, and their feelings are prone to problems.

In fact, bad emotions have a great influence on human health, and it will also aggravate the endocrine imbalance of human body, so mutual understanding and tolerance are needed at this time. Take part in healthy and active social activities. If the conditions are good, you can go out to travel, which is good for your physical and mental health.

Middle-aged men should keep exercising.

Some middle-aged and elderly people's body functions are degraded, the function of motor system is decreased, joints are hardened, and muscles begin to atrophy. Therefore, it is more necessary to insist on physical exercise, such as running, swimming, or practicing yoga and Tai Chi, and of course, you can go to the gym to exercise.

In addition, it is recommended to have a regular physical examination every year in order to know your health status. In general, people's nutritional needs can be met through diet. It is not recommended to take health care products or drugs, especially "aphrodisiac" drugs, or folk remedies, medicinal liquor, etc.
