There is no such thing as what kind of salt is best for the body. Different people are suitable for different kinds of salt, for example, non-iodized salt is suitable for people in coastal areas, and low-sodium salt is suitable for people with high blood pressure. According to whether it contains iodine or not, it can be divided into iodized salt and non-iodized salt. In the vast inland areas of China, iodized salt is recommended because people living in the inland areas consume less seafood and seaweed, and there is a general lack of iodine in food, so the use of iodized salt helps to replenish iodine for the organism. In coastal areas such as Shanghai, Zhejiang, Jiangsu and Guangdong, non-iodized salt is available as residents often consume more seafood, which is rich in iodine. According to the level of sodium chloride content, it can be categorized into low-sodium salt as well as common salt. Low-sodium salt refers to salt with 10%-30% potassium chloride added and only 70%-90% sodium chloride. This type of salt is more suitable for people with high blood pressure or heavy appetite to control the intake of sodium chloride, which is beneficial to the health of the cardiovascular system. People can choose the type of salt according to their actual situation, but overall it is recommended to consume less than five grams of sodium per day to ensure good health.
