Refined salt is a high-quality salt that has been processed and screened. It is usually finer-grained and crystal clear than regular table salt, giving it a more refined appearance. Refined salt is commonly used in cooking, seasoning and food processing to enhance the texture and taste of food. In addition to general edible salt, there are different types of refined salt such as sea salt, rock salt, and Himalayan salt. Refined salt can not only provide sodium ions, but also provide other minerals and trace elements, which have certain benefits for maintaining human health. However, people also need to be moderate in the process of salt intake. Excessive salt intake may have adverse effects on health, so it is necessary to pay attention to reasonable control of salt intake.
