According to Dr. Luiz Moura

Magnesium is vitally important and needs to be taken on a daily basis; everybody should take it, because food today is low in magnesium. The reason for that is very simple: plants need very much magnesium to breath. Their chlorophyllic mechanism is fixation of carbonic gas and elimination of oxygen, which is the opposite of what we do. We do this through a mineral, iron is used for the breathing mechanism of red cells. In plants this is done by chlorophyll whose structure is basically magnesium. What happens is that the chemical fertiliser used today is the NPK, nitrogen, phosphorus and potassium. Magnesium in not being replaced in the soil, and in the past, when cities were all made up of houses with septic tanks, the magnesium we eliminated through feces went back to the phreatic zone. However, today everything goes into the rivers and sea, resulting in an increasingly low rate of magnesium in the soil. The two most important functions of magnesium are: it regulates the metabolism of calcium in the body, it fixates the calcium where it should be and eliminates the calcium where it should not be. Therefore, spinal calcifications, joint, artery calcifications happen due to this lack of magnesium. Kidney calcifications, calcium oxalate kidney stones is due to a lack of magnesium. It is enough to give patients magnesium to dissolve kidney stones, provided they are not urate and phosphate ones. if they are calcium oxalate stones then they are due to lack of magnesium. Magnesium is so important that Dr. Delbet, a medical doctor, used magnesium to wash wounds without knowing why in the 1914 to 1918 war. He published a book in 1940\Nand later he discovered that magnesium also activates the immune system and the proof of this is that, according to the cancer and magnesium maps of Italy and France in his book, the southern half of France where the soil has magnesium the death rate from cancer is less than 3.5% and in the north of France, where the soil is poor in magnesium, more than 8.5% of people died from cancer. In Italy it is much worse, it is very interesting how a decree by one of the Cesares in force until today has consequences until today and so many people die from cancer without knowing why. In Prof. Pierre Delbet's book entitled 'The Preventive Policy of Cancer', he shows the incidence of cancer from the north to the south of Italy. Because of a decree still in force, from an emperor, one of the Roman Cesares, it was forbidden to carry salt from one region to another in order to prevent salt becoming more expensive, and because of this and as the north of Italy is very in rock salt mines, earth salt that only contains sodium chloride and zero magnesium, the incidence of cancer ranges from 7% to 10%. In central Italy, where the capital Rome is located, people use sea salt and as they have more money, they use a salt with a tiny little bit of magnesium, 0.08%, the incidence of cancer drops to 4.5%. And in the south of Italy, which is a rural area, because of the poverty, people use the salt that is given to cattle, which is a salt very rich in magnesium, but turns into water, it becomes brine and every Italian family has wooden vats, where they put the salt and as it turns into water they use this water to season the food. This is their millenary tradition, and for this reason in the south of Italy the incidence of cancer doesn't reach 2%, just because of the magnesium contents. This is described in Prof. Pierre Delbet's book, this is why he considers it so important. Do you know where this chloride comes from? From the salt produced at the Barrilha industry, in Sao Pedro de Aldeia. From the salt produced in Cabo Frio they remove the magnesium to increase the commercial value of the salt. The salt that contains a lot of magnesium cannot be packed, because it would burst the package. It is highly hygroscopic, it becomes humid, so the magnesium is removed from the salt so it can be displayed on market shelves, nicely dry and also it does not block the salt-cellar. The drier the salt, the less magnesium it contains. When magnesium is removed, the salt becomes more expensive and has less magnesium and is drier. Pure Magnesium Chloride At the shop where I buy it, B. Herzog, at Miguel Couto street, it is sold as packed at the Sao Pedro da Aldeia factory. Now there are many factories that remove the magnesium from the salt to sell it separately.
