1, The physiological function of water

Water is the source of life, it is indeed the most pertinent evaluation, since the first day of life in the formation of water, the role of the water in the body of life has not changed.Water is known on Earth and our body the most abundant Material, one 8The baby in the list is near 6List of weight water, an adult body 70%Water is not only rich in the human body, because all metabolic reactions occur in the water medium, so the water is also the necessary material in life.For the human body, it is involved in life movement, remove the body of harmful toxins, to help metabolism , To maintain aerobic breathing, etc. Its role and function is unique.

A variety of different physical and chemical properties of water, so that it bear a variety of key body functions, water quality of life, which includes:

① help digestion: we eat into the mouth of the food, after the teeth chew and saliva moist, from the esophagus to the stomach, completely digested and absorbed the process, and these links need water to participate in. And we need nutrients Only enough to dissolve in water, can be absorbed.

② transport nutrition: water will be fully dissolved nutrients, transported to cells, in turn metabolites out of the cells, the water also transport a variety of bioactive substances such as: hormones, enzymes, platelets, blood cells, etc. Water to cell metabolism process Chemical function carried out smoothly.

③ excretion of waste: water is a very good solvent and suspension medium, many substances dissolved or suspended in water, and can form a new material through a variety of reactions. This property can make the body's metabolic process of waste and toxins. Various ways to excrete the body, and these excretion methods need to participate in water to achieve.

④ lubricating joints: water is the main source of human joint lubrication.Water as a solvent with a variety of viscous molecules together to form a lubricating joint lubrication fluid and the formation of lubrication of the digestive tract and urinary system of viscous liquid, lubricating visceral slurry and formed in the food through Lubrication of the saliva and other digestive tracts during digestion.

⑤ balance body temperature: the water after the absorption of heat, its own temperature change is relatively small, due to this heat capacity, the water through the absorption of heat, produce and evaporate sweat to release heat to help the body regulate body temperature, keep the body temperature normal.

⑥ maintenance of cells: water is an important component of human body structure.It promotes cell metabolism, involved in maintaining the normal behavior of cells and the composition of the integrity of the cell membrane.It also through its recoil to maintain the entire organ.Construction of the body structure also need it Help and maintain the skin's lubrication and elasticity.The regulation of cell water synthesis state and volume plays a key role in maintaining normal cellular function.

Above is the main physiological function of water, in fact, the main water is to maintain the body's water balance, that is, 'quench their thirst' and people often mentioned drinking water can provide the amount of minerals and other nutrients is very limited, so countries Of the nutrient survey data did not estimate the nutrient content of drinking water. This is not to deny the benefits of nutrients contained in drinking water, but only to say that it provides the amount of nutrients in the whole body accounted for a small share of intake , You can not estimate.

2, The body has acidic and alkaline points of it

In many of the propaganda articles on drinking water and health, even in some books of experts and scholars about drinking water, it is mentioned that 'human body fluids are weakly alkaline, PH value 7.35-7.45Due to bad eating habits PH Descent, forming an acidic body 'and said:' acidic constitution is a million disease resource '. In a book on healthy water even made:' the world has 70%-80%Of people belonging to unhealthy acidic body, there are more than 90%Of people died of high-risk diseases caused by acidic physique ', etc. In fact, these statements are unscientific, some are completely wrong.

1.Mentioned above Lt; / RTI & gt;Is the blood of a person PH Value, but can not be understood as human body fluids PH Because the human body fluids in addition to the blood, but also contains intracellular fluid, extracellular fluid, gastric juice, intestinal fluid, urine, etc. Their PH Values ​​are not the same. (Extracellular fluid PH = 6.8-7.0, Gastric juice PH = 0.9-1.5, Intestinal fluid PH = 8.4, Urine PH = 5-6The blood is only human body fluids 1/12So the blood PH = 7.35-7.45Can not be said to be human body fluids PH value.

2.In the theory of Western medicine and Chinese medicine, there is no so-called 'acidic body' 'alkaline constitution' argument. The human body in order to carry out the normal victory of the blood of hydrogen ions (H+) Concentration must be maintained within a certain normal range, while the hydrogen ion concentration is normal to rely on the body's own regulatory function when the metabolism of acid into the blood when too much carbonic acidCO2) Excreted by the lungs in vitro, when the metabolism of non-volatile acids and bicarbonate into the blood, too much from the urine through the kidneys to exclude the body, there are human body fluid this huge buffer system, it can instantly correct the blood PH Value of the fluctuations. To maintain the dynamic balance of the body's acid and alkali.Only rely on diet and other external factors, it is difficult to change this balance.

3.Sometimes human blood PH (But this is not the so-called acidic and alkaline constitution.) This happens only in the state of illness (fever, dehydration, shock, hypoxia, lung, renal dysfunction Etc.), there have been metabolic disorders, causing acid and alkali imbalance occurred in acidosis or alkalosis. In fact, human blood PH As long as less than 7.35Is compensatory acidosis 7.45, Is compensatory alkali poisoning, so that the body is in the state of appeal to the disease will make PH The value of the occurrence of partial acid, partial alkali changes, rather than PH The value has changed and caused the disease.

In fact, the human body is composed of various organs of a sophisticated machine, he has its own body to maintain the stability of the body environment, regardless of the body that part of the PH Value can be maintained within a constant range only in the strict control of the acid-base balance, the body's physiological function to normal operation, and maintain human health.

4.Water hardness and health

In the daily life, often someone asked, is to drink soft water is good or drink hard water is good? What kind of water pestle health benefits. In fact, good and bad drinking water, can not use soft water or hard water to distinguish. Domestic and foreign supermarkets can see the French EvianYiyun )Mineral water, hardness 293mg / L , Vittel Mineral water hardness 307 mg / L , United States MANA (Hawaiian Ocean Deep Water )hardness 300 mg / L Are hard water, while Canada's 'Barbara' glacier water, hardness only 1.54 mg / L Norway VOSS Artesian Water (Fusi )Glacier water hardness 1.17 mg / L , France Volvic Natural mineral water hardness 60 mg / L , Japan's 'Mount Fuji' delicious water hardness 27 mg / L , Are typical of soft water, the hardness of these water gap is large, but are world-renowned high-quality drinking water, good for human health can not use soft water or hard water to distinguish between their good and bad.

5.water PH And healthy

China's new "drinking water health standards" in the provisions of the water quality monitoring indicators 106Item, and PH The value is only one of the sensory and general chemical indicators.PH The value is set to: 6.5-8.5) 1958The World Health Organization's first edition of the guidelines for drinking water PH The value is: 6.5-9.2In 1984The second edition of the guidelines for drinking water provides: 6.5-8.5.2003The third edition of the guidelines for drinking water provides: 6.5-8.0In 2006The third edition of the revised text that: Although the indicators of human health is not dangerous, but the control parameters for water treatment should be taken into account, PH The value should be controlled at6.5-9.5.

According to China's experts, although PH Usually has no direct impact on the consumer, but it is one of the most important water quality parameters in the operation. At all stages of the water treatment must be carefully controlled PH , To ensure that the water clarification and disinfection to achieve satisfactory results.To effectively carry out chlorination, PH Preferably below8.
