Mr. Gupta, a 91 year old veteran, who is also known as father of India’s gemstone industry, has been on a mission to rid salt of harmful substances. He has been spearheading a campaign to expose corrupt practices by the salt industry in the production and marketing of salt and provide healthy variant of salt to people. “Leading companies in the edible salt manufacturing industry are simply repackaging industrial waste laden with hazardous chemicals like iodine and cyanide and marketing it as packaged edible salt, making people vulnerable to diseases like cancer, hyperthyroidism, high BP, impotence, obesity and kidney failure,” says Shiv Shankar Gupta.
