How to choose mineral water?

Overall utility from a bottle of water is not as straight from the source. But if no such possibility, at least, choose life. After all, many waters, which are now sold, artificial, according to the formula they coincide, for example, famous brands of mineral water, but the structure they have another. Doctors at Resorts know very well that the therapeutic effect of artificial water is much smaller. 

By the way, do not think that the best water - the one that was brought from afar, and it is likely that, breaking through the hole in the country, you become the owner of the source of this mineral water. But for safety and in order to know the composition of your water, be sure to return it for analysis. 


How to read a label? 


Expiration. Water, like food, can spoil. So pay attention to the date of bottling and keep in mind: water in glass bottles stored up to 2 years, and in plastic - 18 months. 

Chemical and physical analysis. The label must indicate the date and name of the laboratory, which were analyzed. These must be renewed every 5 years, so if your bottle does "1995", to drink water from it not worth it. 

Category. Depending on the quantity and composition of mineral salts, water is: oligomineralnaya, mineral or slabomineralnaya, sulfate, chloride, calcium, magnesium, sodium, fluoride, containing bicarbonates, glandular, sodium, acid, microbiologically clean. Each - its peculiarities. 

Precipitate. Audiences can only drink mineral water - those that contain no more than 500 mg of salt per liter. Water with salinity from 500 to 1500 mg / l drink can only be alternated with a dining room, otherwise the body will begin the accumulation of salts, especially sodium. As for water, a liter of which contains more than 1500 mg of salt, then it must be consumed only on prescription. It is no longer drink, and medicine! 


SALT WATER 


Bicarbonate water. Contains: more than 600 milligrams of bicarbonate per liter. 

Best for: people who are actively involved in sports, babies (especially with frequent vomiting), and patients with cystitis. 

Contra: those who suffer from gastritis, because in such water contains carbonic acid anhydrides, and in large quantities it can hurt. 

Sulphated water. Contains: more than 200 milligrams of sulfate per liter. 

Best for: those who have liver problems in addition, this water is given a laxative effect. 

Contra: as sulfates can interfere with absorption of calcium (and hence the formation of bones), this water should not drink to children and adolescents. 

Chloride water. Contains: more than 200 milligrams of chloride per liter. 

Recommended: chlorides, often combined with sodium to help regulate the intestines, biliary tract and liver, so the water is to drink to those who have problems in this area. 

Contra: people suffering from high blood pressure. 

Magnesium water. Contains: more than 50 milligrams of magnesium per liter. 

Recommended by: in stressful situations, since magnesium is involved in the mechanism regulating the body's reaction to stress. 

Contra: people prone to indigestion. 

Fluoride water. Contains: more than 1 milligram of fluoride per liter. 

Recommended by: pregnant women, people suffering from osteoporosis (especially useful for her to alternate with water rich in calcium), as well as those who live in an area where fluoridated tap water. 

Contra: adults and children who take fluoride tablets and live in areas where tap water is fluoridated. 

Glandular water. Contains: more than 1 milligram of iron per liter. 

Best for: people suffering from iron deficiency anemia. 

Contra: those who pro6lemy with stomach and duodenal ulcers (including peptic ulcer disease). 

Acid water. Contains: more than 250 milligrams per liter of carbonic acid anhydrides. 

Best for: those with lowered gastric acidity. 

Contra: people with gastritis, ulcers, hyperacidity, flatulence. 

Sodium water. Contains: more than 200 milligrams of sodium per liter. 

Recommended by: in poor digestion (in conjunction with the chloride water). 

Contra: high blood pressure and those who spelled low salt diet. 

Calcium water. Contains: more than 150 milligrams of calcium per liter. 

Best for: people who are not drinking milk, pregnant women, and children and adolescents. According to recent studies conducted in the U.S., this water lowers blood pressure in hypertensives. 

Contra: no strict contraindications. 

SOFT AND HARD 

One of the main characteristics of mineral water - its rigidity, that is, the degree of the total content of calcium and magnesium. Hard water is recommended for children, the elderly and those suffering from osteoporosis. Soft as good fit for the preparation of infusions, decoctions, medicinal syrups, liqueurs. True, some scientists believe that soft water contributes to the development of cardiovascular disease, but no serious evidence of this yet. 

Acidity 

The pH indicates the acidity of water and indicated by scores on a scale from 0 to 14. The ideal pH level for mineral water - 7. Water with a pH indicator is greater than 7 are alkaline, and less than 7 - acid. However, even if you want to reduce the acidity of gastric choose water with pH slightly above 7.
