What water to drink and how to drink it?

Water is the source of life, no matter how high or low you have to drink water. The water-related products on the market can be described as a variety of mineral water, mineral water, pure water, natural drinking water can only be considered a big road, there are such as bamboo charcoal water, moon water, glacier water, weak alkaline water, small molecule group water and other strange and bizarre consumer concepts. We ordinary people face so many concepts of how to choose?

Mineral water, pure water, mineral water, what is the water?

Mineral water

Mineral water is naturally gushing from deep underground or drilling collection, it has strict requirements for water sources, need to go through the geological and mining departments to explore and evaluate, take water source protection measures, can be understood as a mineral resource. The price of mineral water is relatively high, mainly because of the high cost of water, not because of the trace amount of minerals really have any magical effect.

Mineral water because it comes from deep underground, its composition is more influenced by the composition of the rock layer, so compared to domestic drinking water, it has more elements to control, such as antimony, barium, boron, nickel, silver, etc. in domestic drinking water are just unconventional indicators. And mineral water often boasts of the rich “micronutrients” strontium, selenium, etc., in fact, my colleagues have measured several mineral water, the content of these substances is not higher than the tap water, and some are even worse than the tap water.

Pure water

Purified water is used to meet the health standards for drinking water as raw materials, through ion exchange, reverse osmosis, distillation and other processes made. It has low ion content, low water hardness, almost no minerals, and it will not form limescale when used to boil water. The popularity of pure water is very high in developed countries and regions, which can reach more than 80%, and almost all residents in the Middle East drink pure water.

Mineral water

Mineral water is simply pure water with a small amount of minerals, it is drinking water (tap water) after purification, and then add minerals, after sterilization can be made. The purpose of adding minerals is actually not because how nutritious these minerals are, less will not work, but because these minerals can meet the consumer’s requirements for taste. By adding mineral salts, the taste of mineral water can be close to the usual drinking water or mineral water.

“Moon water” and “small molecular group water”

The main marketing concept of the legendary “moon water” exclusively for maternity is “small molecule water” (also known as small molecule water), which is said to be more conducive to absorption. In fact, the so-called “large molecular group of water” is dozens of water molecules to hydrogen bonds to form a cluster, “small molecular group of water” is a few water molecules to form a small cluster, but because the hydrogen bond itself is weak, so no matter which cluster-like structure is unstable.

Businesses have blown “small molecule cluster water” to the sky: in addition to maternity, the elderly can drink to remove blood lipids, oxygen free radicals, children drink to help intellectual development. But there is no water purifier can really produce “small molecule group water”, let alone a reliable literature to prove that this water has any magical effect, all the information about the efficacy of this water, are from the sellers of such products. If you really want to drink “small molecular group water”, why not boil it and drink it while it is hot, because heating will also destroy the “large molecular group water”, into “small molecular group water”.

Similarly, there are magnetized water, quantum resonance information water, hydrogen-rich water, oxygen-rich water, electrolytic water, bio-ion energy-catalyzed water, ion restructured water and other “scientific concepts” that make consumers confused, but none of them are recognized by the scientific community, do not believe it.

Minerals are important, or pure is more beneficial to health?

Beijing’s “most water-drinking families” claim not to drink tap water for 20 years, not because the tap water is unsafe, but that “drinking mineral water is healthier. This statement has been criticized by many people, and even questioned that this is a mineral water brand self-hype. Their theory is based on a literature report. However, the literature also mentions that people who drink mineral water have larger busts and grow taller, and when many indicators like this point to mineral water, it is necessary to consider whether other confounding factors, such as nutritional status, socioeconomic status, etc. In fact, “mineral water is better than other water” has never been recognized by the scientific community.

Are the minerals in water good for health?

Minerals usually refer to inorganic salts, the more common ones in water are carbonates of sodium, potassium, calcium and magnesium, and metasilicates. Some other elements are also present in water, such as iron, zinc, manganese, molybdenum, vanadium and so on. Do not deny that these elements are needed by the body, but the main way we get these nutrients or three meals a day. In general, if you do not lack, drinking mineral water will not let you overdose, if you lack, by drinking mineral water can not make up. As for the mineral water is rich in calcium, can prevent osteoporosis, it is not reliable.

The average Chinese person eats about 400 mg of calcium per day, the daily reference intake of adults is about 800 mg-1200 mg (for ease of calculation, we will use 1000 mg), that is, the average gap of about 600 mg. The high calcium content of mineral water is only 30 mg-40 mg/liter, adults drink 2 liters a day, they drink about 70 mg, equivalent to 7% of the reference intake, equivalent to 12% of the calcium intake gap. If you drink water for calcium, you need to drink 17 liters of water every day, which is almost the amount of a large bucket of water, so it is not reliable to rely on mineral water for calcium or to prevent osteoporosis.

Calcium supplementation still mainly relies on dietary intake and nutritional supplements. Soy foods and dairy products are good sources of calcium, for example, 1 tael of tofu has 80 mg of calcium, while 100 ml of milk has 100 mg. If you still need calcium, in addition to balanced nutrition, you can choose foods with high calcium content or foods labeled “high calcium” or “contains calcium” according to the nutrient content on the food label. If the calcium deficiency is serious, you can take some dietary supplements, such as common calcium tablets, under the advice of your doctor.

Long-term drinking pure water is not healthy?

Some people say that although pure water is clean, but the useful minerals are filtered out, long-term drinking will dissolve the body’s trace elements are discharged, is not conducive to health. First of all, the main way we intake nutrients or diet, the minerals in water is only a very small part. Secondly, the nutrients are not a flush of water, people are not sieves, not so simple.

Some people say that drinking pure water will be calcium deficient, but in fact the most important factor leading to calcium deficiency is insufficient dietary calcium intake, but also related to hormone levels, vitamin levels, sunlight exposure, exercise, etc., and what we drink water is not related.

Another rumor about pure water and calcium is that drinking pure water will remove calcium and lead to osteoporosis. This is a lack of understanding of human physiology, leading to calcium loss is mainly age, hormone levels and dietary intake, bone calcium deposits are not like the dirty things on clothes, a soap rubbed on it. The concentration of ions in human body fluids is relatively balanced, and calcium ions are no exception. A 60 kg adult has 36-42 kg of body fluids, and drinking only 2 liters of water a day will have little effect on the concentration of calcium ions.

If drinking pure water will be deficient in calcium or decalcification, then the people of the Middle East, where drinking water is basically pure water, will not be able to stand it in the first place. And developed countries have been drinking pure water for decades, pure water penetration rate of more than 80%, the public health sector has not found a correlation between pure water and a specific disease or a certain type of disease. The general lull in this, most of them are selling mineral water, mineral water or any other water-related products.

Drinking a lot of hard water for a long time will lead to stones?

The people of China always like to scare themselves, the water is soft for fear of calcium deficiency, hard water and fear of stones. In fact, it is multiple factors that lead to stones, especially their own metabolic abnormalities, but also related to climate, diet structure, genetics and other factors. Epidemiological findings, water hardness and stone incidence is not necessarily linked, both water hardness in areas with a low incidence of stones, but also low water hardness in areas with a high incidence of stones.

If we look at it from a more macroscopic view, even if it is hard water, the mineral content in it is still minimal compared to the three meals a day. And drinking enough water can also prevent stone formation to some extent, because by diluting the urine, the crystallization and precipitation of urine salts can be reduced.

Acid and alkaline, overnight, thousands of water, rumors are chaotic
Weak alkaline water is healthy?

No matter weak acid or alkaline water, drinking it into the stomach will first become acidic, because our stomach is about pH 2.0 gastric acid, and then to the intestinal tract, never mind what water becomes alkaline again, which is the environment that our digestive tract bacteria like.

Our body is a sophisticated buffering system, for example, the normal range of blood pH is 7.35-7.45, which is the only way to ensure that all physiological functions are normal. The weak alkalinity of water comes from minerals, such as carbonates and metasilicates, but the physiological impact of these trace minerals on the human body is simply not comparable to the macronutrients from the diet. Even the so-called acidic and alkaline foods cannot significantly change the pH environment of our body fluids, let alone water.

Overnight water, steamer water, thousands of boiling water will lead to poisoning and cancer?

These waters are actually boiled water, some are stored for a long time, some are boiled repeatedly. Rumor has it that there are many nitrites in these waters, which can cause poisoning and even loss of consciousness and death in severe cases, and nitrites are also carcinogenic. Long storage, boiling, repeated distillation can indeed make the water part of the nitrate into nitrite, but the nitrate content of the water itself is very low, boiling is not possible to make the nitrate increase out of thin air, can be converted into nitrite is less.

As for the claim that nitrite in water causes cancer is also a bit exaggerated, nitrite itself is actually not carcinogenic, the transformation into nitrosamines is carcinogenic, and the transformation requires many prerequisites, not boiling water can be generated. More importantly, even if it is a toxic substance, the key to poisoning is in the dose.

Nitrite is a legal food additive, and is also used normally in Europe and the United States. Its Acceptable Daily Intake (ADI) is 0.07 mg/kg, which is equivalent to 4.2 mg per day for a lifetime for a 60 kg adult. We consume far more nitrates and nitrites from processed foods and vegetables than we get in water.

Nitrite poisoning is usually food poisoning caused by treating nitrite as table salt, often in catering units or collective canteens, which generally leads to poisoning requiring more than 200 mg. The nitrite in the water is very little, even if it is repeatedly boiled or steamed pot water is only more than 100 micrograms per liter, less to say that you have to drink 1 ton of water to reach the amount of nitrite poisoning.

Others say that nitrates are not good to drink more, then I suggest drinking plain water, because the nitrate limit in drinking water (tap water) is 10 mg per liter, groundwater sources are 20 mg, and mineral water is 45 mg.

Water dispenser, water purifier, how to use, how to drink?
Is the water dispenser good?

As long as the barrel itself is qualified, water fountains boiled water is not a problem. To put it bluntly, it is not a bucket of water inserted into the electric kettle well.

It should be noted that a large bucket of water is about 19 liters, according to the family of 3 each day at home to drink 1 liter of water to drink a week or so, this time bacteria can flourish in the bucket. In addition, the cold water intake of water fountains are often contaminated with mold, so it is generally not recommended to drink cold water directly from the water fountains, and do not use this water to brew milk for babies.

Overall, water fountains should be cleaned regularly, the population of small families is not recommended to use water fountains, directly boiled water both economic and hygienic. The unit’s drinking fountains are good for regular cleaning, drink faster, hygiene is actually okay, not sure if you drink hot.

How about water purifiers?

In general, tap water is safe and reliable as long as it meets national standards, without a water purifier directly boiled is good water, with a water purifier is actually mainly for a psychological comfort. Sense of origin is domestic, Japan, Germany, the United States or Mars, the principle of the water purifier is no more than activated carbon adsorption, ion exchange resin, reverse osmosis membrane, the key is that these supplies need to be changed once every few months, if not, and no water purifier is about the same.

Some water purifiers will also add mineralized components, claiming that the dissolved trace minerals are more conducive to health, but if you have the budget, directly buy barrels of mineral water is a more convenient choice.

So, the effect of home water purifier is completely “believe it is spiritual, do not believe it is not spiritual”, because in addition to the warranty of the machine itself, there is no quality control measures, if not well maintained, by bacteria, fungal contamination is normal, it is not good enough to become a source of secondary pollution of tap water.

Now some neighborhoods and coin-operated water purifiers, it is just an enlarged version of the home water purifier, water purification equipment for barrels of water companies shrunken version. If not properly maintained, also and home water purifier, facing a variety of pollution risks, it is not as reliable as boiling cold white.

Tap water, spring water and stream water, choose to choose to choose uncertainty

Is there any health risk of bromate in water?

Bromate is carcinogenic to experimental animals, but no direct evidence was found in humans, so the International Agency for Research on Cancer classified it as “possibly carcinogenic to humans” (category 2B). Bromate is produced by the ozone disinfection process, in which the bromides naturally contained in water are oxidized to bromate by the action of ozone.

China has set the limit for bromate at 0.01 milligrams per liter in the “Sanitation Standard for Drinking Water” and the “Food Safety Standard for Natural Mineral Water” with reference to international standards. In this limit value below the water, lifelong drinking will not have health problems, even if occasionally exceeded, in fact, the impact on health is also very small, just this can not constitute an excuse for unfavorable regulation, but there is no need for consumers to be alarmed.

Is there a problem with the chlorine in tap water?

Water disinfection is generally direct chlorination or the use of chlorine dioxide and other chlorinated substances, the formation of hypochlorous acid and free chlorine, producing sterilization and antibacterial effect. Tap water needs to have a certain amount of “residual chlorine” so that it can remain clean and sanitary when it leaves the plant and goes through the pipe network to your home, and the “smell of bleach” that is often referred to is the result of free chlorine.

As with ozone disinfection, chlorine disinfection also produces some by-products. For free chlorine, just boil it and it will basically run out, so don’t worry about that. For the small amount of other chlorine formed, the World Health Organization considers the health risks associated with it to be much less than the risks associated with non-sterilization. From a risk-benefit analysis point of view, there is no doubt that chlorination is better for consumer health. Moreover, the concentration of chlorine residual that is harmless to humans, as deduced from animal studies, is about 5 mg per liter, which is much higher than the level of chlorine residual controlled by national standards and is therefore generally safe.

Mountain springs and streams are pollution-free and healthier?

Wild springs and streams are indeed natural, but natural does not guarantee safety, it may be contaminated by bacteria and parasites from “natural” wild animal droppings. In addition, weather activities, geological activities can also have an impact on water quality, which is why the earthquake to strengthen the monitoring of water quality.

And whether it’s bottled water, barrel water or tap water, there is quality control by the producer and supervision and inspection by the regulator. Although sometimes it may not be done well enough, and from time to time you can find some exceedances and pollution problems, but overall safety is still guaranteed.

The most basic advice is not to take water from wild sources on your own, especially unfamiliar sources and still sources. If you must drink, try to collect water from upstream, do not store for a long time, and to boil before drinking, to prevent food-borne diseases caused by microorganisms.

After the health problems of water, then drinks and juices

Is it good to drink sports drinks?

Sports drinks are mainly designed for athletes who play intensive, high-intensity sports to replenish their energy and speed up the elimination of fatigue after exercise, and their ingredients often contain some sugar, vitamins, and some sodium and potassium to replenish the loss of sweat. This drink is not suitable for the general population to drink as water, especially for diabetics. If people who sit in the office all day long drink sports drinks as water, it is obviously unhealthy, and in addition to too much energy, they may have consumed more sodium. Since it’s called a sports drink, let’s get our legs moving and sweat more, and then consider whether we should drink sports drinks!

Are fruit juices more nutritious and healthy?

With the improvement of living standards, people are also more health-conscious, and some parents feel that giving their children juice is more nutritious than drinking water, and some parents even start giving juice as water to their children from infancy.

In fact, fruit juice can never replace fruit because the pulp is also rich in other nutrients such as dietary fiber, but also has a stronger sense of satiety and will not eat too much. More and more parents are beginning to know not to give their children high-sugar carbonated drinks, in fact, fruit juice is also rich in sugar, as well as water will lead to excessive energy intake. Parents should let their children develop the habit of drinking plain water when they are thirsty, and at the same time encourage children to eat fruit, rather than holding on to a variety of fruit juice drinks.

Water, how to choose, how to drink?

How should consumers choose water science?

The fundamental purpose of drinking water is to meet the body’s demand for water. Water is the body’s nutrients and metabolic waste carriers, it is only a carrier, no matter what to drink water is not possible to use it as a source of nutrition, nor is it possible to have any magical effect. Therefore, as long as the water is in line with national standards can be safe and secure drinking, there is no “which water is healthier” problem, consumers do not need to drink what water and tangled. Balanced diet, to ensure adequate water, moderate exercise and a good routine, is the fundamental health.

Where the water is blown to the sky are deceitful, where the “miracle water” can cure diseases are suspected of false propaganda, they will not bring you health, will only make you spend more money in vain.

How to drink water?
The average adult needs about 2 liters of water a day, of which about 800 ml can be obtained from food, so also drink about 1200 ml. If it is summer, or a lot of exercise, sweating, you should drink some more. The air in the north is dry, you can also drink more water as appropriate.

Drinking water should be a small number of times, to consciously take the initiative to drink water, rather than feel thirsty and then drink, especially the elderly do not feel sensitive, more need to replenish water in a timely manner. Wake up in the morning to drink a glass of water, do not drink too much water before going to bed at night to avoid frequent night. Do not drink a lot of water immediately after strenuous exercise, it is better to drink slowly. For people with stone body and kidney stones, you should drink more water to reduce the precipitation of urine salt.
