Q. What is Table Salt?

Answer

Table salt the most extensively used is derived from subsurface salt sources. It undergoes rigorous processing steps to get rid of contaminants which might also minimize traces of minerals. It is then finely ground. In 1924 iodine a trace mineral was added to salt to avoid gaiter and hypothyroidism both of which are caused by lack of iodine. Anticaking agents such as calcium silicate are typically used in table salt to avoid clumping.
