Is the addition of potassium ferrocyanide and potassium iodate to edible salt harmful to the human body?

Just saw an article about the addition of potassium ferrocyanide anti-caking agent to the human kidneys of edible salt, there are no experts and professors in this area can tell us.

Is pure salt bad? Why do you have to add these chemicals that are harmful to the human body?

Initially because the salt is damp plated, resulting in salt being disliked no one to buy, in order to solve the problem that salt is not sold by the salt, the salt industry company has added anti-knotting agents that meet international standards in the salt, and now with the improvement of people's knowledge level and living standards, people's favor for natural foods is also more and more intense, and salt is an indispensable necessity in people's daily lives, and its safety is also valued by more and more people, based on the cooking methods of most of the residents of our country are fond of stir-frying, The addition of anti-caking salt at a high temperature of about 200 degrees will release harmful substances to the human body, therefore, the demand for non-added anti-caking salt is also increasing, many residents began to buy no added natural well salt table salt online, and some people choose to buy hardened table salt, in order to avoid salt containing anti-knotting agent.

It is hoped that the big salt companies will keep pace with the times and provide salt without anti-caking agents to some people in need.
