A kind of “bitter mineral water” appeared in the

market, claiming that “it contains more than 30 kinds of minerals beneficial to human body and its content is very high. Some of the mineral contents are hundreds or even thousands of times of the same kind of products, which can be called the best in water”. Then it is “European royal exclusive” and “limited production”, which has the characteristics of typical luxury goods. In the efficacy description of

and

, this kind of water is more integrated with the most marketable functions such as “detoxification”, “fat clearing”, “weight loss”, “beauty”, “liver nourishing”, “endocrine regulation” and “immunity enhancement”, which is comparable to the water in the jade bottle of Guanyin Bodhisattva.

and

however, this kind of water, whose price is staggering, is not only unreliable in its functions, but also problematic in its basic safety. If you pay attention to the composition of this mineral water, you will find that it is indeed “extremely high in mineral content”. General mineral water, calcium, magnesium, sodium content is dozens of milligrams per liter, potassium only a few milligrams, iodine basically does not contain. However, the contents of calcium, magnesium and sodium in each liter of bitter mineral water are more than 300, 5000 and 1700 mg respectively, potassium is close to 700 mg, and iodine is close to 400 μ G. Are these minerals

and

beneficial to human body? Although these minerals are needed by the human body, their health effects are inverted bell shaped – less is bad, more is harmful. Whether they are “beneficial” or “harmful” depends on whether the intake solves the “lack” problem or exceeds the “safe upper limit”. In order to achieve different “health functions”, the recommended drinking amount of this water is between tens and hundreds of milliliters per day. Taking 200 ml daily for example, the contribution of calcium, magnesium, sodium and potassium is about 60, 1000, 340 and 140 mg respectively, while iodine is close to 80 μ G.

and

adults need about 1000 mg of calcium a day, most people can’t reach it, so bitter mineral water is a little useful for calcium supplement. The recommended intake of

and

sodium is no more than 2400 mg (corresponding to 6 g of salt), which many Chinese will exceed. Too much sodium increases the risk of high blood pressure, so this 340 mg of sodium is harmful.

and

are good for the heart health of the general population, but most people’s intake is far from “excessive”, so the potassium content is not good or bad. The problem of

and

iodine is more interesting. The average person needs 150 micrograms a day, and pregnant women need 250 micrograms. In most areas, there is not enough iodine in the food and it needs to be supplemented with iodized salt. According to the mainstream understanding of “iodine supplement” and “iodine excess”, these dozens of micrograms of iodine may not have much problem. However, because of the hype of public opinion, many people are full of doubts and even fear for iodized salt, while iodine in bitter mineral water is regarded as “health care ingredient”, which is really interesting. The bitterness of

and

mineral water is mainly caused by magnesium. With the addition of a large number of sulfate anions, this water is equivalent to a high concentration of magnesium sulfate solution. Another name for magnesium sulfate is bitter salt. In medicine, it is the active ingredient of laxatives. Therefore, drinking such mineral water is equivalent to taking laxatives, which naturally leads to diarrhea. Many people regard this kind of diarrhea as “detoxification” and “fat clearing”, so they think it “works”.

and

have long-term diarrhea, which naturally has “weight loss effect”, which is exactly the same as taking laxatives. It should be noted that, not to mention that this kind of weight loss is at the cost of body damage, it can not maintain itself. Once diarrhea is stopped and normal eating is stopped, it will quickly rebound. The standard usage and dosage of laxatives is much more reliable and safe than this “natural product”.

and

magnesium are also trace components needed by human body, and adults need hundreds of milligrams per day. Usually, people can get it from food, even if it is not enough, it will not be “magnesium deficient”. Excessive magnesium will cause “magnesium poisoning”, diarrhea is the performance of “magnesium excess”. The recommended standard in the United States is: adults should supplement magnesium with no more than 350 mg per day. 200 ml bitter mineral water more than 1000 mg, equivalent to the “safety standard” three times. Such water is no longer suitable for drinking. And marketing advertisements, not only to healthy people, even pregnant women and patients are not let go, it is really terrible. Many people like hot spring bath. Generally speaking, bathing in a hot spring makes people feel comfortable. Besides the water temperature and relaxed mood, it may also be related to the minerals contained in it. After all,

and

hot spring baths are not always available. Therefore, some people steam such water to get “bath salt”, so that they can simulate “hot spring bath” at home. This bath salt is also called “cathartic salt” because the main ingredient is magnesium sulfate. In China, there may not be many people in the “salt bath”. People generally only use it to soak their feet. The so-called “bitter mineral water” of

and

is probably used to make “pickled salt”. In the process of soaking feet, even if some minerals can be absorbed through the skin, they can not be “excessive”. If you drink it directly, you should be thankful that it does not harm your health. Please don’t expect it to be “healthy”.
