In the corridors of All India Institute of Medical Sciences in New Delhi, a young doctor named Chandrakant Sambhaji Pandav began to see a quiet tragedy. Children with goitres, mothers with fatigue, minds that never reached their full potential—all linked to something as simple as missing iodine in the diet.

He completed his MBBS and MD in Community Medicine at AIIMS, then travelled to McMaster University in Canada for advanced training in health economics, clinical epidemiology and biostatistics. When he returned, he carried a clear purpose: iodine deficiency was preventable, and India could lead the way.

In the 1980s the National Iodine Deficiency Disorders Control Programme still focused mainly on the Himalayan belt. Chandrakant argued it had to become universal. He worked with policymakers, scientists and salt producers, explaining that every household needed iodised salt. Resistance was strong. Some said the cost was too high; others doubted the need.

One senior official asked him, “Doctor, why push so hard for something so ordinary?”

Chandrakant answered evenly, “Because an ordinary pinch of iodised salt can protect a child’s brain for life. That is not ordinary. That is the foundation of a nation’s future.”

He became a founding member of the International Council for Control of Iodine Deficiency Disorders and later Regional Coordinator for South Asia. As a WHO and UNICEF consultant he travelled to more than sixty countries, carrying the same message. In India his advocacy helped make universal salt iodisation a national policy. Goitre rates fell. The label “Iodine Man of India” settled on him with quiet respect.

He served as Professor and Head of the Centre for Community Medicine at AIIMS, trained generations of public-health doctors, authored hundreds of papers and advised national nutrition missions. Even after formal retirement he continued as President of the Indian Coalition for Control of Iodine Deficiency Disorders and a member of the National Council on India’s Nutrition Challenges under Poshan Abhiyaan.

In 2021 the nation awarded him the Padma Shri for his contribution to medicine and public health. He accepted it as recognition of a long collective effort.

Today, when young doctors ask him what sustained him through decades of quiet advocacy, Dr. Chandrakant Sambhaji Pandav smiles and says, “A single grain of iodised salt can change a life. Multiply that by a billion, and you change a country. That is enough reason to keep going.”

From the lecture halls of AIIMS to remote villages and international councils, he has spent a lifetime turning an invisible deficiency into a visible victory for public health.
