The nutritional and physiological role of water is very complex, and many special physiological functions in the process of animal life activities depend on the existence of water.
1.Water is the main component of an animal's body. Water is one of the main structural substances in the cells of the animal organism.
The water content of the early development of the fetus is as high as more than 90%, about 80% of the newborn young animals, and 50-60% of the adult animals. The general rule is that it decreases with age and weight gain. Water, like air, is an absolutely indispensable substance for animal life.
2.Water is an ideal solvent. Because water has a high electrolysis constant, many compounds are easy to be electrolyzed in water and exist in the form of ions, and the metabolism of water in animals is closely combined with the metabolism of electrolytes.
Most cytoplasm is a mixture of colloids and crystals, making water solubility particularly important. In addition, water is used in the gastrointestinal tract as an intermediate medium for the transport of semi-solid chyme, and also as a carrier of blood, tissue fluid, cells, secretions, excretions, etc. Therefore, the absorption, transport and excretion of various nutrients in the body and the excretion of metabolic wastes must be dissolved in water before they can be carried out.
3.Water is the medium of all chemical reactions. The dissociation of water is weak and belongs to the inert substance.
However, due to the action of enzymes in animals, water is involved in many biochemical reactions, such as hydrolysis, hydration, redox, synthesis of organic compounds and cell respiration processes. All polymerization and depolymerization in animals are accompanied by the binding or release of water.
4.Regulates body temperature. The specific heat of water is large, the thermal conductivity is good, and the heat of evaporation is high, so water can store heat energy, quickly transfer heat energy and evaporate heat loss energy, which is conducive to the regulation of the body temperature of homeothermic animals.
The rapid flow of blood in the blood circulation, panting and sweating, restricting blood flow through the body surface during cold stress, etc., all help the animal to keep its body temperature constant. Water conducts heat better than other liquids and contributes to the dissipation of heat from deep tissues. If the animal muscle is active continuously for 20 minutes, there is no water to dissipate heat, and its temperature can make the protein coagulate.
The evaporation and heat dissipation of water is more important for animals with sweat glands.
5.Lubricating effect. The water in the tissue fluid in the joint capsule, in the body cavity and between the organs of the animal body can reduce the friction between the joints and organs and play a lubricating role.
In addition, the protective buffering effect of water on the nervous system such as cerebrospinal fluid is also very important; When there is a large amount of water loss in the body due to extensive burns and symptoms such as severe vomiting and diarrhea, it is necessary to replenish fluids in time to prevent severe dehydration and aggravation of the condition.

There are many kinds of water, mineral water, distilled water, and soda. Which one do you want to ask?

The main nutrients of water** are minerals such as potassium, sodium, calcium, magnesium and other ions in water.
Water is a living organism, a foot-wide nutrient that is indispensable for the survival of animals and plants. At the same time, the Great Sleepy Zen Water is also dusty, and it is the most abundant ingredient in the human body. As long as there is enough water, a person can survive for several weeks without food; But if there is no water, a few people will die in a few days.
Therefore, whether you like to drink boiled water, tea or soup, you must consume enough "water nutrients" every day to maintain the normal operation of this complex machine of the human body.
Benefits of Water:
1. Water has a regulating effect on climate.
2. Water is an important part of all living organisms. Water in the human body accounts for 70% of body weight; Water is essential for sustaining life.
3. Essential substances for the daily life of human beings on the water. Such as cooking, washing, bathing, cleaning, and so on.
4. Industrial production is inseparable from water. Such as raw material water, product treatment water, boiler water, washing water, cooling water and so on.
5. Water conservancy is the lifeblood of agriculture. Agricultural production requires a large amount of water for irrigation.

1.No.
2.However, life is inseparable from water.

Water is not nutritious.
People can live for weeks or even months without food, but without water, they can die in a few days, which shows how important water is to the human body.
Water is the physiological element for all life processes to function properly, and all biochemical processes must be carried out in water. Because nutrients and the products of dissimilation are mainly transported in a water-soluble state. At the same time, water contains sodium, calcium, magnesium, potassium and other inorganic salts, which are indispensable substances for most animals and plants, and the ingestion and excretion of water also help animals and plants regulate body temperature.
It can be seen that water, especially the water we drink daily, is not only essential for cleanliness, hygiene and safety, but also plays an important role in human health.

No, water is essential for human life activities, but water has no nutrients.
-
If it is pure water, it is not nutritious, but it is necessary for the human body.
Mineral water contains a variety of trace elements, which can replenish essential minerals for the human body, but it is not suitable for long-term consumption, because it may lead to excessive accumulation of trace elements.
The most beneficial to the human body is low-molecular-weight weakly alkaline water. It can also be drunk alternately with mineral water and purified water.

Water is the king of white medicine and contains a lot of minerals!
It has the effect of transporting nutrients and detoxifying.
At least 1500ml a day, if you feel too much, you can also eat fruits to replenish water.
If you have a constitution with a lot of yang deficiency and phlegm, drink less.
so as not to be poisoned by water.

Water is the source of life. Man's need for water is second only to oxygen. If you don't consume a certain vitamin or mineral, you may live for a few weeks or for years, but if you don't have water, you can only live for a few days.
1.Water is needed for various physiological activities of human beings, such as water can dissolve various nutrients, fats and proteins must become a colloidal state suspended in water before they can be absorbed; Water flows endlessly between blood vessels and cells, transporting oxygen and nutrients to tissue cells, and then excreting metabolic wastes from the body.
2.Water plays a role in thermoregulation. When a person breathes and sweats, some water is excreted.
For example, in the hot season, the ambient temperature is often higher than the body temperature, and people rely on sweating to evaporate water and take away part of the heat to reduce body temperature and save people from heat stroke. When the weather is cold, the body temperature does not fluctuate significantly due to the low external temperature due to the great potential of water to store heat.
3.Water is also a lubricant in the body. It moisturizes**.
**If you lack water, you will become dry and lose your elasticity, and your face will look old. Some joint capsule fluid and serous fluid in the body can prevent friction damage between organs and can rotate flexibly. Tears and saliva are also lubricants for the corresponding clan officials.
4.Water is the cheapest and most powerful medicine in the world. The health and disease prevention effects of mineral springs and electrolyte water are well known.
Mainly because the water contains ingredients that are beneficial to the human body. When you have a cold or fever, drinking plenty of boiled water can help sweat, reduce fever, and dilute the toxins produced by bacteria in the blood. At the same time, there is more urine, which is conducive to accelerating the excretion of toxins.
5.When there is a large amount of water loss in the body due to extensive burns and symptoms such as severe vomiting and diarrhea, it is necessary to replenish fluids in time to prevent severe dehydration and aggravation of the condition.
7.Drink a glass of water before bathing to keep your skin youthful and energetic Always drink a glass of water before bathing. When you sweat twice as much as usual, your metabolism accelerates, and when you drink water, every cell in your body absorbs water, creating smooth and delicate skin.

I only know the nutrients in mineral water.
The nine limit indicators specified in the national standard include lithium, strontium, zinc, selenium, bromide, iodide, metasilicic acid, free carbon dioxide and total dissolved solids, and one or more of the mineral water must meet the requirements of the limit index, and the required content is (unit: mg L): lithium, zinc, iodide, selenium, bromide, metasilicic acid 25, free carbon dioxide 250 and total dissolved solids 1000
Most of the mineral water on the market belongs to the strontium (SR) type and metasilicic acid type.
To put it bluntly, it is lithium, strontium, zinc, selenium, bromide, iodide, metasilicic acid, free carbon dioxide, and total dissolved solids.

Commonly used water includes tap water, purified water, mineral water, and is one of the basic substances on which all living organisms depend. Plain water easily penetrates the cell membrane to promote metabolism in the body and improve the body's immune function. Most of the mineral water has the functions of softening blood vessels, strengthening bones, promoting the synthesis of hemoglobin, enhancing appetite, and regulating central nervous system activity.
Purified water only has the function of solvent and simple water replenishment.
