Salt: an essential mineral
Although salt comes in for some criticism today, we should remember that it is essential for our cells and those of all the animal species.
Salt is the main source of sodium* in our diet, a mineral that is essential because it cannot be produced by the organism. Sodium helps to distribute water round the body and regulate blood pressure and volume.
It is also essential to the correct functioning of the muscles, the movement of nerve impulses and the smooth working of the heart.
Recommended consumption is 5 to 6 g per day.
Iodine in salt
Iodine is one of the essential trace elements, which is found in small quantities in our organism. Iodine enters into the composition of the hormones produced by the thyroid gland. In the foetus and young child, these hormones regulate the growth and development of most of the organs, particularly the brain. An iodine deficiency can lead to goitre and a delay in intellectual development.
In certain countries, the salts used in the food industry may be iodized to avoid deficiency. Sea salt no longer contains iodine once it has been rinsed and drained. Iodine is therefore added to the salt in very precise proportions in accordance with the regulations in force in the country. Salt is therefore a good vehicle as it is used everywhere as part of the diet.
*Sodium helps to maintain normal muscle function. A reduction in sodium consumption helps to maintain normal blood pressure.
