Commonly used edible salt types: low sodium salt, potassium iodide salt, seaweed salt, spirulina salt, green food edible salt and so on. Different salts have different functions in different ways:

1, buy salt according to cooking needs. Salt with large particles, especially coarse salt, is suitable for pickling food, which is not only good in flavor, but also beneficial to the slow dissolution and penetration of salt.

2. When cooking daily, the salt with large particles dissolves slowly. When reaching the same salinity, more salt is added, which is not conducive to controlling blood pressure. On the contrary, salt with small particles is easy to disperse evenly, which is more suitable.

It should be noted that the main function of salt is to provide salty taste, no matter what salt needs to be limited. For healthy people, if you only eat 6 grams of salt every day, whether it is iodized salt or low sodium salt, it will not cause trouble.

If you eat too much, it will reach more than ten grams or even twenty grams a day, even the so-called "high-grade salt" will still be harmful, and you will eat high blood pressure, stroke and osteoporosis. Low sodium salt is high in potassium and is not recommended for patients with renal insufficiency and heart disease.

Extended data:

In addition, according to the source of raw materials, salt is mainly divided into four categories: sea salt, lake salt, well salt and rock salt (mineral salt).

1. Sea salt is made by introducing seawater into saltworks, insolating, evaporating and crystallizing.

2. Lake salt is salt extracted directly from salt lake or dried in salt field with salt lake brine as raw material;

3. Well salt is made by drying underground natural brine; Once, due to geological movement, seawater became salt water on land. Rock salt is formed by long-term evaporation and crystallization of salt-bearing substances. They are buried deep underground100 ~ 3000m, and can only be made by drilling wells, injecting water, dissolving and extracting. These salt raw materials will become different kinds and names of products after the following different treatments.
