Iodized salt is to add a certain dose of potassium iodide and potassium iodate to common salt, which can prevent iodine deficiency and is suitable for normal people and people with iodine deficiency. Because iodine plays an important role in human basic life activities, physical development and brain development, it can synthesize thyroid hormone and affect human health. However, due to environmental factors, the human body is prone to iodine deficiency, so the country has produced this kind of iodized salt to meet people's demand for iodine.
Non-iodized salt-hyperthyroidism patients?
Non-iodized salt is a refined salt without iodide. Iodine intake has two sides. Excessive iodine supplementation can lead to hyperthyroidism or hypothyroidism. However, the probability of iodine exceeding the standard caused by eating iodized salt is very small. However, it is not excluded that some people who originally suffered from mild hyperthyroidism took iodized salt, which aggravated the symptoms of hyperthyroidism. Hyperthyroidism and autoimmune thyroiditis have certain heredity, so people with family history of such diseases should pay attention to iodine intake in their lives. This kind of people can eat non-iodized salt, or eat mixed salt of iodized salt and non-iodized salt, and eat less seafood, which can also prevent the occurrence of the above diseases.
Low sodium salt-hypertensive people?
The purity of sodium chloride in traditional table salt is above 95%, but replacing part of sodium chloride in low sodium salt with potassium chloride, the sodium content is only 65% ~ 70%, which can effectively reduce the risk of cardiovascular diseases such as hypertension and heart disease. The content of potassium in low sodium salt has increased. Because potassium is also one of the essential trace elements for human body, a proper amount of potassium helps to lower blood pressure, and the taste of potassium chloride is close to that of sodium chloride, so it is very suitable for the above people to eat. However, it should be noted that if people with renal insufficiency consume too much potassium, they will not be able to excrete it and accumulate in the body to form complications such as hyperkalemia, which will have adverse consequences. Therefore, people with renal insufficiency should eat less even with low sodium salt.
