The more refined the salt, the less useful it is.
Salt consists of two components — sodium and chlorine. Each gram of salt holds 400 grams of water. That's why an excess of salt in the diet leads to edema nutritionist Nadezhda Pakhirko.
Salt itself is not so harmful — only its regular use for a long time and in excessive quantities is harmful. The norm of salt intake is not more than 5 grams per day.

Scientists studying the properties of salt have long come to the conclusion that the more refined the salt, the less useful it is. But the more impurities, the lower the quality of the salt — gray color, grains, small pebbles, etc.
⠀
Extra salt There are two types: fine and bleached. To obtain such salt, it is boiled for a long time and bleached using different types of processing. Of course, there are almost no useful substances left.
⠀
Rock salt. In my opinion, the most harmful. It is taken out of the ground. It contains many impurities: sand, pebbles, earth and other waste that may be in the earth. Cleaned with a chemical treatment.
⠀
Iodized. As you understand, iodine is added on purpose. During heat treatment, most of the iodine evaporates.
⠀
Marine. This salt is obtained by evaporating sea water. Contains 98% sodium chloride and 2% beneficial minerals. When dried at high temperatures (approximately 650 degrees), its natural chemical structure is destroyed.
⠀
Himalayan salt. This is my favourite. From the name it is clear that it is mined in the Himalayas on the territory of the former ocean, dried up millions of years ago. Its exceptional value lies in the fact that it is mined by hand. It is dried in the sun and not subjected to any processes.
Himalayan salt can contain from 70 to 85 elements. Regular salt contains only sodium chloride. Scientists explain such a quantity of useful substances by the origin of salt — when the continents moved, it was enriched by mixing with volcanic magma.
