There’s a very healthy and vibrant discussion on table salt, sea-salt, Saindhava lavanam and Himalayan salt. I may add that tablet salt is totally avoidable as it contains added aluminium to avoid lumping. Aluminium is one of the contributory causes of Alzheimer’s disease.
Iodine is also added in the name of reducing goitre. Sea-salt of yesteryears was clean and healthy. It was before coal-based power-generation was introduced. Coal is full of Mercury. Once it goes into the clouds, it comes down in the form of rain, which our rivers take it to the ocean. Mercury is a deadly poison. Regarding Himalayan salt, it contains 94 minerals including iodine, as authenticated by the Institute of Biophysical Research, Las Vegas, Nevada, USA in June 2001. Health-conscious individuals may opt for it as it is proved to be healthy.I. Venkateswarlu
