We can't say which is better, iodized salt or non-iodized salt. It depends on whether there is iodine deficiency in the diet and whether it needs to be supplemented.

1. People in inland areas: Medical data show that normal people should not consume more than 6 grams of salt every day, and the iodine content is about 150 micrograms. Too much or too little intake will have a negative impact on the body. However, people in some inland areas are often short of iodine, so iodized salt can only be used to supplement the iodine needed by the body and prevent related diseases, so it is suitable for eating iodized salt.

2. People in coastal areas: People in coastal areas often eat a lot of seafood, and their bodies are generally not short of iodine, so they are suitable for eating non-iodized salt. If patients have thyroid nodules, hyperthyroidism, hypothyroidism and other diseases, the requirements for iodine intake are different. They should see a doctor in time, clarify the specific reasons, understand the iodine intake, and actively treat according to the doctor's advice.
