In addition, unreasonable diet will lead to malnutrition and improper nutrition, such as being too thin or obese, which will accelerate the pace of aging. Although there are many factors affecting human aging, including social pressure, disease, nutrition, exercise, mental mood, environment, climate and so on. If the diet is unreasonable and the nutrition is unbalanced, it will affect the internal environment of the body and destroy the process of biological metabolism in the body, thus accelerating the aging of the body. The so-called "old mouth".
Most common and frequently-occurring diseases of the elderly are not "cold in a day". These diseases often begin in the prime of life. After middle age, the body gradually ages and degenerates, and its metabolic function declines, and the physiological functions of various tissues and organs decrease, especially the digestive function of gastrointestinal tract, which makes the metabolism in the body affected by the quality and quantity of diet and makes the nutrition out of balance. Overnutrition will not only lead to obesity, but also lead to cardiovascular and cerebrovascular diseases and diabetes. Therefore, people should pay attention to: reasonable diet, balanced nutrition, health care, prevention-oriented consciousness.
What's more, an unreasonable diet will greatly increase the risk of cancer.
Many cancers are closely related to environmental factors, and diet is the closest contact between people and the external environment, so the relationship between food and cancer is very close. A large number of experimental investigations and animal experiments show that many digestive tract cancers are closely related to diet, and long-term bad eating habits are the most direct factor of human carcinogenesis.
Therefore, if we can reasonably adjust the diet structure and balance nutrition, it will be of positive significance to prevent and fight cancer.
As can be seen from the above, an incorrect and unscientific diet is a great threat to our health. Therefore, reasonable and scientific eating habits are one of the important factors to keep healthy. But people's living conditions are different and their eating habits are different. For example, hunger and satiety due to wealth tend to be different due to temperament, thus gradually forming corresponding physical differences.
Hunger and satiety are different, which refers to the amount of food intake. If the family has money, they can eat as much as they want. Poor families barely maintain food and clothing; Poor families only eat coarse grains and miscellaneous grains, and often they don't even have food. Generally speaking, a person with a good diet has good nutrition, so he has a plump figure and a good physique; And people with insufficient diet have poor nutrition, and most of them are thin. People who eat so-called good things when they are full are mostly obese, and their physique is not necessarily good, which is prone to some "rich diseases"; Although the poor only eat meager food, coarse grains contain many nutrients necessary for human body, and they have to work for their lives, so their physique is often better. Therefore, the essay on reading a doctor says: "People with wealth live and prosper. Zang-fu organs and meridians are all phlegm and saliva, and qi stagnation can't circulate, so people who can't get rid of evil spirits are not deficient in vital qi, but deficient in vital qi. Poor people, Holly is not full, his failure is not warm, he works hard in the four seasons, his sweat often leaks, his glory is weak, and his meridians wither.
