The influence of nutrition on health, people need to get some nutrients from their diet every day, and only the nutrients in food can prolong life. If people lack basic nutrition for a long time, people will be in a sub-health state. Let's learn about the effects of nutrition on health.
Effect of nutrition on health 1 Nutrition is the support of life and health.
Nutrition controls health
If the human body is a machine, food is the driving force to ensure the normal operation of this precision machine. The quantity and quality of food can not be guaranteed, which will inevitably affect physical health, mood and energy.
Medical experts believe that insufficient nutrition and unbalanced nutrition are the important causes of many diseases. Therefore, scientific diet and reasonable nutrition supplement are important ways to improve physical fitness, enhance body resistance, reduce and overcome diseases, and achieve health and longevity.
The importance of nutrition to health
Related to brain function
If adults are malnourished, they are prone to fatigue, poor endurance, and decreased attention and memory, which will affect their physical and mental work efficiency. Malnutrition will also have a disastrous impact on the brain development of infants and young children, leading to mental and physical stunting, which cannot be remedied in adulthood, and will also pass on the defects to the next generation.
Relating to the occurrence and development of diseases.
Nutrition is directly or indirectly related to many diseases, such as iron deficiency anemia, iodine deficiency goiter, vitamin D and calcium deficiency rickets. Malnutrition and decreased immunity will increase the prevalence of infectious diseases. Nutritional imbalance often becomes the inducement of obesity, cardiovascular diseases and some tumors, which seriously affects human health and even life-threatening.
Affect endocrine function
Malnutrition will affect endocrine function. Malnutrition in women can lead to amenorrhea, malnutrition in pregnant women can easily lead to premature delivery, and the fetus is prone to congenital malnutrition, congenital malformation or stillbirth. Malnutrition in men can lead to sexual dysfunction and affect fertility.
Important aspects of health care and disease prevention
Rational nutrition is the most basic and important link of health care and disease prevention. Reasonable nutrition can promote tissue regeneration, enhance the body's resistance to diseases, promote growth and development, improve intelligence, and reduce morbidity and mortality. Patients can also shorten the course of disease and accelerate their recovery through diet deployment.
The effect of nutrition on health 2. The important role of nutrition in a person's life is difficult to fully express in words. It can be said that from the embryonic stage to the end of life, the human body needs nutrition all the time, and human growth and development, health level, labor ability and life span are closely related to nutrition. Today, diet, nutrition and health are one of the most important topics in the world.
Nutrition is related to brain function. Malnutrition will have a disastrous impact on the brain development of infants and young children, leading to intellectual and physical development, which can not be made up even after adulthood, and will also pass on the defects to the next generation. Malnourished adults show poor endurance, fatigue, decreased attention and memory, thus affecting the efficiency of physical and mental work.
Nutrition is directly or indirectly related to the occurrence and development of many diseases, such as iodine deficiency goiter, iron deficiency anemia, vitamin D and calcium deficiency rickets and so on. Malnutrition and decreased immunity will increase the prevalence of infectious diseases, prolong the course of disease and affect rehabilitation. Nutritional imbalance often becomes the inducement of obesity, cardiovascular diseases and some tumors, which seriously affects human health and even threatens life. Malnutrition can also affect endocrine function, including gonadal function.
Women will have amenorrhea, and men will have sexual dysfunction, which will affect the fertility rate. Malnutrition in pregnant women can easily lead to premature birth, congenital nutritional deficiency, congenital malformation or stillbirth. Generally speaking, the comprehensive impact of nutrition on health is most profoundly reflected in mortality and average life expectancy.
Rational nutrition is the most basic and important link of health care and disease prevention. It can not only promote growth and development, enhance physical fitness, improve intelligence, improve work efficiency and improve competitive level, but also ensure normal birth, promote prenatal and postnatal care, help to maintain youth, delay aging and prolong life; It can also promote tissue regeneration, enhance the body's resistance to diseases, and reduce morbidity and mortality. Even if you are unfortunately ill, you can shorten the course of disease and accelerate your recovery through diet adjustment during your illness.
For each individual, nutrition is related to functional status, intelligence level, labor ability, immune function, prenatal and postnatal care and life expectancy. For a nation, nutrition is related to the overall quality of the nation, to the health level of a generation or even generations, and to the future of the country and the nation. All this warns people anytime and anywhere: in order to be healthy, we must attach importance to nutrition.
Specifically, balanced diet refers to the establishment of a balanced relationship between dietary nutrition supply and physiological needs of the body in four aspects at the same time, namely, amino acid balance, calorie nutrition balance, acid-base balance and various nutrient intake balance, which are not lacking, unbiased and chaotic. Only in this way can the digestion, absorption and utilization of nutrients be facilitated. If the diet relationship is unbalanced, that is, the diet does not meet the physiological needs of the human body, it will have a negative impact on human health and even lead to some nutritional diseases or chronic diseases.
The amino acid balance and protein nutritional value of food largely depend on the number and proportion of eight essential amino acids contained in food. Only when the proportion of eight amino acids provided in food is close to the proportion needed by human body can human tissue protein be effectively synthesized, otherwise the utilization of protein in food will be affected.
The World Health Organization put forward the proportion of eight essential amino acids needed by human body. The closer the ratio is, the higher its physiological value is. When the physiological value is close to 100, that is, 100% is absorbed, which is called total amino acid balance. A protein that can achieve a complete balance of amino acids is called a complete protein. We can use this standard to score amino acids in protein of various foods.
The amino acid ratio of eggs and human milk is very close to that of human body, which can be called food with balanced amino acids. However, the amino acid composition in most foods is unbalanced, so the nutritional value of protein is affected. For example, high leucine in corn affects the utilization of isoleucine; The high arginine in millet affects the utilization of lysine.
Therefore, the diet based on plant food should pay attention to the reasonable collocation of food to correct the imbalance of amino acid composition. If corn and beans are mixed to make soybean corn flour and soybean millet flour, the utilization rate and nutritional value of protein can be improved.
Calorie nutrients form a balance, and carbohydrates, fats and protein can provide calories for the body. They are called calorie nutrients. When the total calories provided by caloric nutrients are in balance with the energy consumed by the body, when the intake ratio of the three caloric nutrients is 6.5: 1: 0.7, the calories provided to the body are: carbohydrate accounts for about 60% ~ 70%, fat accounts for about 20% ~ 25%, and protein accounts for about10% ~1.
Excessive supply of calories and nutrients can cause obesity, hyperlipidemia and heart disease; Too little will lead to malnutrition and induce many diseases, such as anemia, tuberculosis and cancer. These three calories of nutrients are interactive. When the total heat is balanced, the proportion is unbalanced, which will also affect health.
When carbohydrate intake is too high, it will increase the burden on the digestive system and kidneys, and reduce the chances of ingesting other nutrients. When protein provides too much heat, it will affect the normal function of protein, cause protein consumption and affect the ammonia balance in the body.
When carbohydrate and fat are in short supply, the protection of protein will be weakened. To meet the normal calorie demand of life and work, under normal circumstances, the calorie distribution of three meals a day should be: breakfast accounts for 30%, lunch accounts for 40%, and dinner accounts for 30%, so as to ensure the calorie balance of the day.
The intake of various nutrients is balanced, and there are complex relationships among various nutrients. Different physiological states and different activities have different requirements for nutrients, so it is difficult to grasp the balance of intake of various nutrients. Therefore, the Nutrition Society of China formulated the daily supply of various nutrients. Accordingly, various nutrients in our diet should be kept within the range of 10% of the standard supply for a certain period of time.
This mutual ratio can be called the basic balance between nutrients. It is suggested in the Pagoda of China Residents' Balanced Diet that each person should consume 300-500g of grain, 400-500g of vegetables and fruits, and animal foods such as fish, poultry, meat and eggs 100-200g (50g of fish and shrimp, 50-65438 of poultry meat) every day.
Acid-base balance, under normal circumstances, the PH value of human blood is kept between 7.3 and 7.4 due to its own buffering effect. Eating proper amount of acidic food and alkaline food will maintain the' acid-base balance' of body fluids, but if the food is not properly matched, it will cause physiological acid-base imbalance. When the food is not properly matched and the acidic food in the diet exceeds the required amount, it will lead to blood acidity, deeper blood color and increased viscosity, and even acidosis in severe cases. At the same time, it will also cause calcium deficiency by increasing the consumption of calcium, magnesium and potassium plasma in the body.
This phenomenon is called acidic constitution, which will affect health. Common acidic foods are: egg yolk, rice, flour, chicken, eel, carp, pork, beef, dried squid, beer, peanuts and so on.
Effects of nutrition on health. Nutrition is the source of life. Let's look at a fact. What do you think will happen if a healthy person doesn't eat any food or drink water for 7- 10 days? Besides air and water, food is the main thing that people use to maintain their lives, that is, the nutrition in food gives people life. Nutrition is the source of life. From the moment of embryo formation to the end of human life, nutrition nourishes human life all the time. This is "nutrition and life".
Second, drug control diseases Look at people who are suffering from diseases around us: hypertension, cardiovascular and cerebrovascular diseases, diabetes, gout, hepatitis B, fatty liver, hyperthyroidism, arthritis, gastritis, severe insomnia, cancer and so on. In the face of this pile of common chronic diseases, can diseases be cured by drugs? In fact, the best medicine can do is to control chronic diseases within a certain range, which is good.
Third, nutrition repairs cells and it is definitely not drugs that can really make you recover, because the ingredients of drugs are not the ingredients needed for cell repair. Once given enough time and nutrition, such as protein, vitamins, minerals and fat, the human body will begin the process of self-repair. Because after about six months, most cells in all human bodies will be updated by 90% to produce new tissues.
Gastric cells are renewed every 7 days; Skin cells are renewed every 28 days; Liver cells are replaced every 180 days; Red blood cells are updated every 120 days; In a year or so, 98% of cells in the body will be renewed. As long as the nutrition is sufficient, after a period of time, the damaged organs will be "soft replaced" through continuous "metabolism" and "self-repair" of cells, resulting in "new" tissues and organs. Many, many diseases have a chance to fully recover!
"You can only live once if you try hard, and the richest people can't buy extra time." If we can help more people while harvesting health and freedom, we will only get a limited life and live a healthy, happy, long and quality life. What a meaningful thing!
