There are four determinants of health, namely, internal factors (15% inherited by parents), external factors (10% social environment and 7% natural environment), medical conditions (8%) and personal lifestyle (60%). It can be seen that 68% of the factors are under our control. "If you are sick, you can see Western medicine, and if you are healthy, you can find Chinese medicine. If you want to live a long and healthy life, you must rely on yourself. " . Many people are not sick but ignorant. In the Victoria Declaration, four cornerstones of health are put forward. The first is a reasonable diet, which shows the importance of a scientific diet. So, what exactly do the seven nutrients in the diet do?
I. protein: (Engineer of Human Body) consists of 22 kinds of amino acids, which are the basic substances of life, accounting for 65,438+06% of human body weight. It is used to manufacture human organs such as blood, muscles, skin, hair, nails, etc., control the development process of human body, repair and maintain human tissues, and is widely distributed in human tissues.
2. Fat: (fuel for human body) is one of the main components of various cells in human body.
1, which supplies the energy needed by human body.
2. Fat is distributed in the isolation layer of main organs, joints and nerve tissues of human body. Protect body tissue, avoid mechanical friction, and play the role of heat preservation and fixation.
3. Promote the digestion and absorption of fat-soluble vitamins, such as vitamins A, D, E and K. ..
4. Protect human skin health.
Third, carbohydrates: (the driver of the human body) carbohydrates are also called sugar. It is the main substance provided by human energy. 1 g carbohydrate can release 4 kilocalories in human body. Provide energy for muscle and brain activities, enhance endurance and adaptability.
Vitamins: (33 kinds of nutrition catalysts) Vitamins are indispensable substances for cell metabolism, body development and growth, and maintaining human health. It contributes to the absorption and utilization of protein, fat, carbohydrates and minerals. Chemicals that help form blood, cells, hormones and nervous system. It can be divided into fat-soluble vitamins and water-soluble vitamins. Promote the chemical reaction of nutrition and maintain the normal function of various systems of human body.
1, fat-soluble vitamins: A, D, E, K, etc. Soluble in fat, stored in human adipose tissue, to ensure the functional health of human organs, such as vitamin A: can promote the health of human eye tissue and protect vision; Vitamin d: help the human body absorb calcium and maintain bone health; Vitamin E is a powerful antioxidant, which can protect cell membrane, heart tube, heart, skin and liver from free radical damage and delay aging.
2, water-soluble vitamins: vitamin B and vitamin C, soluble in water but insoluble in fat, can not be stored in large quantities in the body. Therefore, we must take enough water-soluble vitamins every day to supplement the human body's demand for it.
3. There are 8 kinds of B vitamins * * *: B 1, B2, pantothenic acid, nicotinic acid, B6, B 12, folic acid and biotin. Its characteristic is that it can help protein decompose old substances and synthesize new ones. Its personality is to maintain the health of different organs. For example, VB 1 can maintain the needs of the nervous system, help red blood cells to generate and participate in a variety of metabolism, and help the development of nails and hair. Pantothenic acid can help food release energy and maintain the health of nervous system.
Verb (abbreviation of verb) minerals: (psychosomatic regulator) minerals include macro elements and trace elements.
1. Macroelements: accounting for more than one ten thousandth of human body weight, such as carbon, hydrogen, oxygen, calcium, phosphorus, magnesium, sodium and potassium. 2. Trace elements: less than one ten thousandth of human body weight, such as iron, copper, manganese, chromium, selenium, etc.
Minerals are important substances that constitute human tissues, such as calcium, phosphorus and magnesium, which are important components of bones and teeth, and sodium and potassium are important components of extracellular fluid. Metabolism in the human body involves a certain amount of minerals every day. If the mineral intake is insufficient, it will cause many diseases to the human body. Such as osteoporosis, dyspepsia, anemia and malignant tumor.
6. Water: (the transportation network of human body) Water has the functions of forming body fluids, transporting nutrients, regulating body temperature and removing wastes. The human body is 60% water, which can ensure the amount of blood circulation and maintain the normal metabolism of various organs. Lack of water in human body will do harm to life.
Seven, fiber: (human scavenger) crude fiber mostly exists in vegetables, such as celery, leeks and so on. It can keep human intestinal tract clean, promote intestinal peristalsis, expel toxins and ensure stool volume. It is easier to ingest in ordinary vegetables. It can help digestion, remove waste in the body, reduce the absorption rate of cholesterol, produce satiety and help control weight.
The seven indispensable nutrients in the human body can not only ensure life, but also determine other aspects of everyone, such as beautiful appearance, words and deeds, mood, thinking ability, youth, aging and so on.
Nutritionists say, "What you eat determines what kind of person you are." That's the point.
