Types of salt and their health effects

From an early age we discover the importance of salt and not only as an ingredient in food preparation. Salt is made up of a mineral mixture of sodium and chlorine and plays an essential role in a person's daily alimentation. Salt is an inexhaustible natural mineral that is extracted from the sea or from salt mines around the world.

Although it is recommended not to over-salt, this mineral remains an indispensable ingredient for the proper functioning of the human body, as it ensures a balance of fluids in the brain, helps cells absorb nutrients and ensures the transport of electrical impulses to nerves and muscles.

What are the best known benefits of salt?

Salt has countless benefits when consumed in the recommended amounts such as:
  • Helps regulate blood pressure - salt contributes to the efficiency of nerve transmission and muscle contraction. Also, when you suffer from bloating, constipation or lack of appetite, you can add a little salt to the glass of water;
  • In the case of joint diseases, hot baths with salt water give results, having a beneficial effect on rheumatism and relieving diseases specific to the cold season, such as colds, flu or colds. Salt relieves the symptoms of cystitis and annexitis if you take a sitting bath with salt water. You can combine five tablespoons of coarse salt to a liter of water;

How many types of salt are there and what are their benefits?

In stores and hypermarkets, salt is found in countless shapes, textures and colors, but also in different ways of use. The types of salt found in nature are innumerable, and their classification is made according to several important criteria: source or mode of extraction (mine salt and sea salt), degree of refining (coarse salt and extra-fine salt), substances in the composition (sodium chloride, iodine or other substances and minerals) and of course, by geographical area of origin.
Depending on the substances in the composition, different types of salt may differ in taste and color. Differences in color can be seen with the naked eye and those of taste are more difficult to notice, especially when the salt is fine.

Iodized table salt
