What is mineral water?

and

mineral water is simply pure water with a small amount of minerals. It is made of drinking water (tap water) after purification, then adding minerals, after sterilization can. In fact, the purpose of adding minerals is not because these minerals are so nutritious that they can not be used without them, but because they can meet the taste requirements of consumers. By adding mineral salts, the taste of mineral water can be close to that of boiled water or mineral water. What is mineral water?

and

mineral water is naturally gushed out from the deep underground or collected by drilling. It has strict requirements for the water source, which needs to be explored and evaluated by the geological and mineral departments, and the water source protection measures should be taken, which can be understood as a kind of mineral resources. The price of mineral water is relatively high, mainly because of the high cost of water, not because of the magical effect of trace minerals.

and

mineral water comes from the deep underground, and its composition is greatly affected by the rock composition. Therefore, compared with the domestic drinking water, it has more elements to control, such as antimony, barium, boron, nickel, silver, etc., which are only unconventional indicators in drinking water.

and

mineral water often boast that it contains rich “trace nutrients” such as strontium and selenium. In fact, my colleagues have measured several kinds of mineral water, and the content of these substances is not higher than that of tap water, and some of them are even worse than tap water. What is pure water?

and

purified water is made by ion exchange, reverse osmosis, distillation and other processes, which meet the sanitary standards of drinking water. Its ion content is low, the hardness of water is low, almost no minerals, it will not form scale when it is used to heat water. The popularization rate of purified water in developed countries and regions is very high, which can reach more than 80%. Almost all residents in the Middle East drink pure water. Drinking mineral water is more healthy?

and

Beijing’s “most water drinking families” claim that the reason for not drinking tap water for 20 years is not that tap water is unsafe, but that “drinking mineral water is healthier”. This statement has been criticized by many people, questioning that this is the self hype of a mineral water brand.

and

the expert’s theoretical basis comes from a literature report. However, it is also mentioned in the literature that people who drink mineral water have large chest circumference and grow tall, which is simply a high-end foreign-style fairy water! In fact, when many indicators point to mineral water, it is necessary to consider whether there are other mixed factors, such as nutritional status, social and economic status. In fact, “mineral water is better than other water” has never been recognized by the scientific community. Are minerals in water good for your health?

and

minerals usually refer to inorganic salts. The common minerals in water are sodium potassium calcium magnesium carbonate and metasilicate. There are other elements in water, such as iron, zinc, manganese, molybdenum, vanadium, etc. There is no denying that these elements are needed by the human body, but the main way for us to obtain these nutrients is to eat three meals a day. Generally speaking, if you don’t lack mineral water, drinking mineral water won’t make you eat too much. If you don’t, you can’t make up for it by drinking mineral water. It’s usually people who sell mineral water, mineral water and other water related products. Mineral water is rich in calcium, can prevent osteoporosis?

and

the average daily intake of calcium of Chinese people is about 400 mg, and the reference intake of adults is about 800-1200 Mg (we use 1000 for convenience), which means that there is an average gap of about 600 mg. The high calcium content of mineral water is only 30-40 mg / L. if adults drink 2 l a day, they will drink about 70 mg, which is equivalent to 7% of the reference intake and 12% of the calcium intake gap. If you drink water to supplement calcium, you need to drink 17 liters of water every day, which is almost the amount of water in a bucket. Therefore, it is not reliable to rely on mineral water to supplement calcium or prevent osteoporosis.

and

calcium mainly depend on dietary intake and nutritional supplements. Beans, dairy products are good sources of calcium, such as 1 liang of tofu has 80 mg of calcium, and 100 ml of milk has 100 mg. If you need to supplement calcium, in addition to balanced nutrition, you can choose foods with higher calcium content or foods with claims of “high calcium” and “containing calcium” according to the nutrient content on the food label. For example, I eat a kind of high calcium biscuit in the morning, 100 grams contains 300 mg calcium. If calcium deficiency is serious, you can add some dietary supplements, such as common calcium tablets, under the doctor’s advice. Is it unhealthy to drink pure water for a long time?

some people say that although the pure water is clean, it filters out all the useful minerals. If you drink it for a long time, it will dissolve and discharge the trace elements in the body, which is not conducive to health. First of all, our main way of intake of nutrients is diet. The minerals in water are only a very small part. Secondly, nutrient elements are not washed away by water, and people are not sieves, which is so simple.

for example, some people say that drinking pure water will lead to calcium deficiency, but in fact, the most important factor leading to calcium deficiency is insufficient dietary calcium intake, which is also related to hormone level, VD level, sunlight exposure, exercise amount, etc., and has nothing to do with what water we drink. If you drink pure water, you will be short of calcium. How can the people in the Middle East live? They basically drink pure water.

some people say that drinking pure water will decalcify and lead to osteoporosis, which is a lack of understanding of human physiology. The concentration of ions in body fluids is relatively balanced, and calcium ion is no exception. A 60 kg adult’s body fluid has 36-42 kg, but a day’s drinking water volume is only 2 liters, how much impact on the concentration of calcium ions? The main causes of calcium loss are age, hormone level and dietary intake. Bone calcium deposition is not like dirty things on clothes, which can be removed by rubbing with soap.

and

in fact, developed countries have been drinking purified water for decades, and the popularization rate of purified water has reached more than 80%. It has not been heard that anyone who drinks purified water has problems. Generally speaking, most of them sell mineral water, mineral water or other water related products.
