The minerals can be found in mineral water are in ionic form. Among the positive ions or cations include sodium, potassium, magnesium, calcium, and between negative ions or anions are chlorides, sulfates and bicarbonates.
Each of the minerals in general, and we provide mineral water in particular have some specific functions and necessary for the proper functioning of the body.
Magnesium
The magnesium content of an adult is about 2,000 mEq. that amount to about 24 grams, most of which are part of bone tissue. This related to calcium absorption and allowing the establishment of this in the bones and teeth. He recommends taking 420 mg daily in the case of man and 320 mg for women.
The main source of magnesium are nuts like almonds, walnuts, peanuts, hazelnuts and cocoa, grains, wheat germ and whole wheat bread with lesser amounts of green vegetables. They also contain magnesium some animal foods such as cheese, blue fish, molluscs and crustaceans. As for the water to be considered as magnesium should have a magnesium content higher than 50 mg per liter.
Calcium
99% of the body’s calcium is part of the bones and teeth and 1% is present in the blood, fatty tissue and the extracellular fluid. His performance in the organism is closely related to vitamin D which stimulates calcium absorption.
Their content of blood depends on the secretion of two hormones that regulate calcium levels in the blood: calcitonin and PTH.
The recommended dose of calcium varies by sex, age and physiological circumstances. Thus the average dose in women is 1,000 mg dose should be increased to about 1500 mg during adolescence, menopause, pregnancy and lactation. In man the average dose is about 1500 mg.
The main source of calcium is milk and dairy products like yogurt, liquid yogurt, cheese and milkshakes. According to its calcium content in water are classified as “soft” or “hard”. The soft tissues are those which contain almost the hard calcium and those over 200 mg / l.
From a nutritional standpoint hard waters are a considerable daily intake of calcium we need. But are not suitable for cooking or washing clothes (hard to dissolve detergents) and eventually spoil the machines that people use in their operation. The waters are recommended calcium to fight osteoporosis as they involve an extra intake of calcium.
Iodine
Iodine is a mineral needed for the organism whose deficiency causes goiter. In areas where the iodine content is at least 1 nanogram per liter of the incidence of goiter is minimal people. The recommended water with iodine to prevent goiter and are especially useful in areas where no food is eaten that provides iodine such as fish.
Fluorine
Fluoride has a demonstrated ability to protect against dental caries and promote remineralization of tooth enamel. It is also necessary for the proliferation of bone-forming cells (osteoblasts).
The recommended dose is 1.5-1.7 mg per day. The optimum content in water is one part of fluoride per million (1ppm). In some countries fluoride is added as sodium fluoride in the drinking water. This measure is controversial because an excess of fluoride causes fluorosis.
Sodium
The sodium helps retain water inside the body being primarily responsible for the osmotic gradient. This regulates the amount of water and the distribution of the same in the body. Therefore regulates blood pressure and excess causes an increase of it.
The waters with high sodium content will be suitable for people with low blood pressure. By contrast in cases of hypertension are more appropriate low salt water.
Iron
Iron is an essential mineral in the composition of certain enzymes and red blood cells, being the charge of transporting oxygen. The recommended daily allowance is 10 mg to 15 mg for men and women. We can get to the flesh and blood and vegetables and wheat germ.
Ferruginous waters are appropriate to prevent iron deficiency anemia and are appropriate in a time when iron needs are greater as in menstruation and pregnancy.
Sodium Bicarbonate
There is water containing sodium bicarbonate. Ingestion produces antacid effect, stimulating appetite, gastric secretion and muscle tone. In the intestine can stimulate the secretory capacity slightly and peristalsis.

That is definitely extraordinary and so well thought out.Usually I won’t make posts on post on blogs, but I’ve to say that this site really forced me to do so. Actually top notch bit of advice
