Low sodium salt contains 60% ~ 70% sodium chloride, 20% ~ 30% potassium chloride and 8% ~ 12% magnesium sulfate. The sodium chloride content of table salt is generally divided into three levels, the first level is ≥99. 1%, the second level is ≥98.5%, and the third level is ≥97%. It can be seen that the sodium content of low sodium salt is about 1/3 lower than that of ordinary salt, and the potassium and magnesium contents are higher.
Sodium can raise blood pressure, while potassium and magnesium are beneficial to prevent hypertension and protect cardiovascular and cerebrovascular diseases. Therefore, some patients with hypertension and coronary heart disease will buy low-sodium salt on the advice of doctors, but low-sodium salt is not just the exclusive salt for these patients. At present, the daily salt intake of China residents far exceeds the recommended amount of 6 grams. If people can eat low-sodium salt, they can easily reduce sodium by 30% and increase the intake of several hundred milligrams of potassium and magnesium, which is also a wise choice for ordinary people.
Treat all kinds of salt rationally:
There are not many kinds of salt in the domestic market, and nearly 100 kinds of salt may be seen in large supermarkets in developed countries such as Japan. They contain different trace elements, have different colors and are expensive. However, the price level does not necessarily reflect the nutritional value of food, and everyone needs to treat it rationally.
To sum up, the main function of salt is to provide salty taste. No matter what trace elements it contains, it should not exceed 6 grams every day. Most minerals needed by human body can be obtained from diet, and it is neither necessary nor effective to supplement them by eating crude salt. Whether to buy high-priced salt depends on economic ability and consumption purpose. Unrefined sea salt has different flavors from other salts, which can be selected according to cooking needs, but the flavor has nothing to do with health. However, because of the high price of patterned salt, it may be a good thing if people use less salt.
