Pictures of the functions and functions of the seven major nutrients

Pictures of the functions and functions of the seven major nutrients. Nutrients are needed to maintain all life activities and processes such as reproduction, growth, development and survival of the body. Substances taken in from the external environment. The human body cannot live without these seven nutrients. Here are pictures of the functions and functions of the seven nutrients Pictures of the functions and functions of the seven nutrients 1

1. Protein, the technical engineer of the body: It is composed of 22 types of carbohydrates. It accounts for 18% of the body's weight and is the material for growth and tissue repair. It is the basic material foundation of life, just like the body's building decoration materials - steel bars and concrete. It is required to be sufficient and used to produce blood, muscles, skin, hair, fingernails and other internal organs, control the growth stage of the body, and repair and maintain body tissues. Commonly found in body tissues.

2. Fat is the fuel of the body: accounts for 15% of the body, balances energy supply and demand, protects human organs (organs), forms growth hormone, and is an important component of various cells in the body. One is like the home decoration materials of a house, supplement as much as possible. 1. Supply and demand balance the kinetic energy needed by the body. 2. Human fat is distributed among various internal organs of the body and in the isolation layer of joints and nerve tissue. It protects human tissue, prevents mechanical friction, and plays the role of heat preservation and immobilization. 3. Promote the digestion of fat-soluble vitamins, such as vitamins A, D, E, and K. 4. Maintain physical and mental health of the body and skin.

3. Carbohydrates are the controller of the body. Carbohydrates are also called sugar: they account for 2% of the body and are important substances in the energy production of the human body, such as the water and electricity system of a house. 1 gram of carbohydrates can release 4 calories in the human body. Supply and demand balance the kinetic energy required for muscle and head activities, improve physical strength and restore work ability

4. Vitamin nutrients 33 types of metal catalysts: accounting for 1% of the body, vitamins are The body's lubricating oil is an indispensable substance for the basic metabolism of body cells, growth and development of the human body, and keeping the body healthy. It maintains the normal activities of various functions of the body. It is like the body's power switch - when something goes wrong, the endocrine system will be disrupted. ,. It is beneficial to the absorption and utilization of protein, fat, carbohydrates and minerals. Compounds that assist in the production of blood, body cells, growth hormone, and central nervous system. Can be divided into fat-soluble vitamins and water-soluble vitamins. Promote chemical changes in nutrients to maintain the normal function of each system in the body. 1. Fat-soluble vitamins: A, D, E, K, etc. Contained in human fat and stored in fat tissue, it ensures the healthy functioning of internal organs. For example, vitamin D: can promote the health of tissues around the eyes and protect the eyes; vitamin D: helps the body absorb high-quality protein and protect bones. Health; Vitamin E: It is a super powerful antioxidant that protects the cytoplasm, primary cardiac pulsation, heart, skin, liver and other tissues from oxygen free radical damage, and prevents aging and so on. 2. Water-soluble vitamins: There are vitamin B2 group and vitamin C, which dissolve in water but not in fat. The body cannot store large amounts of them, so it is necessary to take in sufficient water-soluble vitamins every day to supplement the body's need for them. 3. There are currently 8 types of vitamin B2 group: B1, B2, pantothenic acid, vitamin B3, B6, B12, folic acid tablets, and biotin. Its mutual characteristic is that it can help proteins break down old substances and generate new substances. Its specialization is to maintain the health of different human organs. For example, VB1 meets the needs of the central nervous system and can help blood cells to produce and participate in many metabolisms, helping to grow nails, hair, etc. Pantothenic acid can help food release energy. and maintain central nervous system physical and mental health.

5. Mineral mind-body controller: Accounting for 5% of the body, minerals contain macroelements and nutrients. 1. Macroelements: accounting for more than one ten thousandth of the body's net weight, such as: carbon, hydrogen, oxygen, calcium, phosphorus, magnesium, sodium, potassium, etc. 2. Nutrients: accounting for less than one ten thousandth of the body weight, such as iron, copper, manganese, chromium, selenium, etc. Minerals are the main raw materials that make up various tissues of the body. For example, calcium, phosphorus, and magnesium are the main components of bones and front teeth. Sodium and potassium are the main components of the internal and external fluids of the body cells.

A certain amount of minerals are involved in the basic metabolism of the human body every day. If the mineral intake is insufficient, it will cause many diseases to the body. Such as osteoporosis, indigestion, anemia, malignant tumors and other diseases. Calcium is like the bricks of the body.

6. Water is the transport network of the body: accounting for 55-65% of the body, it is a melting fluid, lubricating fluid and temperature regulator. Water composes blood, transports nutrients, regulates body temperature, and removes waste. 60% of the human body is water. Water can ensure the blood circulation of the body and maintain the normal metabolism of the human internal organs. Not enough water in the body can have adverse effects on life.

7. Cellulose body cleanser: Dietary fiber is found in natural plant foods, such as lettuce, amaranth, etc. It can maintain the cleanliness of the human intestinal tract, promote gastrointestinal function, metabolize toxins, and ensure the amount of defecation. It is easier to absorb in ordinary vegetables and fruits. It can promote digestion, eliminate body waste, reduce cholesterol digestion, create a feeling of fullness, and help control weight. The seven major nutrients are indispensable in the human body. In addition to ensuring life, they can also determine other aspects of a person: such as a person's appearance, speech and behavior, mood, thinking, youth, decline, etc. Nutrition experts say: "What you eat determines what kind of person you are." This is what nutrition experts are talking about. Picture 2 of the functions and functions of the seven major nutrients

Water: the source of life

Water is an indispensable nutrient for the human body, and it is also the solvent for various nutrients and metabolic waste. Nutrients and metabolic waste are carried to their destination with the help of water flow. Hormones secreted in the human body also reach the whole body through this pathway to exert their effects. 90% of blood is water, accounting for about 60% of human body weight, and is an important factor in ensuring human health;

Protein: sustaining life

Protein is the basic component of human tissue. It is an important material basis of the body. Every cell and all important components of the body must be involved in protein. Protein is digested and decomposed into amino acids in the human body. It can be said that without protein there would be no life.

Fat: Don’t be imbalanced

Fat is another type of nutrient that the human body requires in large amounts. Includes neutral fats and lipids. The important physiological functions of fat include providing essential fatty acids, carrying fat-soluble vitamins, providing heat energy, and feeling full.

Carbohydrates: Source of Energy

Carbohydrates are the most economical and main source of calories for humans to obtain from meals. Including monosaccharides, disaccharides, polysaccharides and dietary fiber in food.

Minerals: Essential

Minerals are also called inorganic salts. It has been found that more than 20 kinds of inorganic salts are necessary for the human body. Among them, those with large amounts and relatively stable contents are called macroelements, such as calcium, phosphorus, potassium, sodium, magnesium, chlorine, and sulfur. The rest, whose content is small and fluctuates greatly, are called trace elements, such as copper, iron, iodine, zinc, manganese and selenium.

Vitamins: Maintaining Health

Vitamins can be divided into two categories, namely fat-soluble vitamins (such as vitamins A, D, E, K, etc.) and water-soluble vitamins (such as vitamins B, C etc.). It neither supplies heat energy nor constitutes body tissue, but participates in countless cellular activities. Although the human body requires very little of it, when lacking any vitamin, physiological metabolism will be severely affected, and it is very important for maintaining human health.

Cellulose: required for metabolism

Cellulose is a carbohydrate. Including: cellulose, hemicellulose, lignin, pectin, etc., which are not digested and absorbed by the human body after ingestion, forming waste residue, which is excreted with the stool; it can promote intestinal peristalsis, and at the same time absorb excess fat, cholesterol, etc. and be excreted from the body , effectively prevent the occurrence of cardiovascular diseases and gastrointestinal diseases in adults.

What do the seven major nutrients include?

1. The seven major nutrients include water

Water is an essential ingredient for humans and animals, including all An important condition for living things to survive. Water can transport various substances necessary for life and eliminate unnecessary metabolites in the body; promote all chemical reactions in the body; regulate body temperature by dissipating a large amount of heat through unconscious water evaporation and sweat secretion; synovial fluid in joints, respiratory tract and gastrointestinal tract Mucus in the tract has a good lubrication effect, tears can prevent dry eyes, and saliva is helpful for moistening the pharynx and swallowing food.

2. The seven major nutrients include protein

If the human body is regarded as a building, then protein is the building material that makes up the building. Important components of the human body: blood, muscles, nerves, skin, hair, etc. are all made of protein; protein also participates in the renewal and repair of tissues; regulates the physiological activities of the human body and enhances resistance; protein also produces energy, supporting the growth and development of children. Provides energy, so it is also an energy-producing nutrient.

3. The seven major nutrients include fat

Fat is the main nutrient for storing and supplying energy. Each gram of fat provides twice as much energy as the same weight of carbohydrates or protein. The formation of body cell membranes, nervous tissue, and hormones are all inseparable from it. Fat also plays a role in keeping warm and insulating; supporting and protecting internal organs, joints, and various tissues; and promoting the absorption of fat-soluble vitamins. Babies need 4 grams of fat per kilogram of body weight every day. Fats from animal and plant sources are necessary for the human body and should be provided in combination. Daily fat heat supply should account for 20% to 25% of total calories.

4. The seven major nutrients include carbohydrates

Carbohydrates are the main nutrients that provide energy for life activities. They are widely found in rice, noodles, potatoes, beans, and various foods. Among miscellaneous grains, it is the most important and economical food for human beings. The daily calories provided by this type of food should account for 60% to 65% of the total calories. Any carbohydrates that undergo biochemical reactions in the body are eventually decomposed into sugars, so they are also called sugars. In addition to providing energy, it also promotes the metabolism of other nutrients, combines with proteins and fats to form glycoproteins and glycolipids, and forms antibodies, enzymes, hormones, cell membranes, nervous tissue, ribonucleic acid and other substances with important functions.

5. The seven major nutrients include vitamins

Vitamins are a class of compounds necessary to maintain normal physiological functions of the human body. They do not provide energy and are not essential for the body. It is a structural component, but it is absolutely indispensable in the diet. If a certain vitamin is lacking or insufficient for a long time, it can cause metabolic disorders and pathological conditions to form vitamin deficiency.

6. The seven major nutrients include inorganic salts

Inorganic salts are salts in inorganic compounds, formerly known as minerals. They generally only account for 1~1.5% of the fresh weight in biological cells. , more than 20 kinds have been found in the human body, among which macroelements include calcium Ca, phosphorus P, potassium K, sulfur S, sodium Na, chlorine Cl, magnesium Mg, also known as macroelements, and trace elements include iron Fe, zinc Zn, selenium Se, molybdenum Mo, fluorine F, chromium Cr, cobalt Co, iodine I, etc. Although the content of inorganic salts in cells and the human body is very low, it has a very powerful effect. If you pay attention to a diversified diet, eat less animal fat, eat more brown rice, corn and other whole grains, and do not eat too much refined flour, you can reduce the inorganic salts in the body. Salt should be maintained at normal levels.

7. The seven major nutrients include dietary fiber

Dietary fiber can be divided into soluble dietary fiber and insoluble dietary fiber. The former includes part of hemicellulose, pectin and gum, etc., and the latter includes cellulose, lignin, etc. Among them, apple collagen, as a natural macromolecular water-soluble dietary fiber, has the function of strong adsorption and elimination of "positively charged radioactive substances" from the human body. It is an essential nutritional balance element for the human body. It has a unique molecular structure and physiological characteristics that cannot be directly digested by the human body, so that it can naturally adsorb "toxins", "negative nutrients", "heavy metals", "free radicals" and other harmful substances that are difficult for the human body to metabolize itself and excrete them from the body. Thus achieving nutritional balance.
