Coarse salt is generally relatively uncommon in our daily lives. What type of salt does this coarse salt generally belong to? What is coarse salt usually used for? What effects and functions does it have?
What is coarse salt?
Coarse salt is a crystal formed by frying and drying salt water from sea water or salt wells, salt ponds, and salt springs. It is natural salt and is unprocessed. Large grain salt is mainly composed of sodium chloride, but because it contains impurities such as magnesium chloride, it is easy to deliquesce in the air, so the humidity should be paid attention to when storing.
From the perspective of consumption, coarse salt has more benefits for the body, mainly because it contains chemical components needed by the human body. From a taste point of view, coarse salt is too salty, so I am more accustomed to using fine salt. From a pollution point of view, salt in seawater contains a lot of pollutants and heavy metals. Although it can supplement some of the substances needed by the human body, the real effect is not that ideal.
Efficacy and functions of coarse salt
1. Strengthen yang and waist: promote sexual function, produce sperm and aid fertility.
2. Remove fat and lower blood pressure: make blood pressure easier to control, dilate capillaries, reduce blood viscosity, and improve microcirculation.

Can coarse salt be eaten?
Coarse salt is edible. Before refined salt became popular, everyone ate coarse salt for a long time.
Coarse salt is a crudely processed edible salt, so it contains more impurities. Not only are the particles larger, but the color is darker.
Because coarse salt contains more impurities, it is easier to get moisture. When storing coarse salt, you must pay attention to the sealing problem.
Because coarse salt has not been finely processed and does not add necessary trace elements and iodine, long-term consumption may cause iodine deficiency.
Appropriate amount of coarse salt can promote the secretion of sebaceous glands and increase the tenderness of the skin to a certain extent.
Because coarse salt is relatively cheap, it can be used to pickle pickles, duck eggs, etc. But be sure to control your salt intake.
Will coarse salt expire?
There are two opinions on whether table salt will expire. One is that it will not expire. This statement means that the main component of table salt is sodium chloride. , chemical properties are very stable. Like sugar, table salt is often used to preserve food and is a natural preservative. However, if the iodized salt we often eat is not protected from light and high temperatures, the iodine content will be reduced if left for too long, and the salt will agglomerate, but the quality of the salt will not change and will not affect consumption. Therefore, the state does not regulate the shelf life of ordinary edible salt.
Another way to say that it will expire is that although it does not affect consumption no matter how long it is kept, whether it is pure salt or iodized salt, iodized salt has a shelf life, mainly because of the iodine in it. The ingredients are easily oxidized and decomposed. After the shelf life of 18 months, the iodine content is very low and cannot supplement iodine.
