Sir Robert McCarrison (born March 15, 1878 – died May 18, 1960) was a doctor and expert in nutrition from Northern Ireland. He worked for the Indian Medical Service, which was a medical group for the British in India. He was recognized for his important work, becoming a Companion of the Indian Empire in 1923, receiving a special 'knighthood' title in 1933, and even becoming a special doctor to the King in 1935.
McCarrison was born in Portadown, County Armagh, Northern Ireland. He finished his medical studies at Queen's College, Belfast in 1900. He then joined the Indian Medical Service. He was sent to work as a medical officer for Indian soldiers guarding the northern mountains. He was promoted several times, eventually becoming a Major-General in 1933. He retired from the Indian Medical Service in 1935.
McCarrison's early research in India focused on understanding the cause of goitre, a condition where the thyroid gland swells. His work gained wide attention, and he was promoted to do more research in 1913. In 1928, he became the Director of Nutritional Research in India. He stayed in this role until he retired in 1935 and moved back to England, settling in Oxford.

Pioneering Nutrition Research
McCarrison was a true pioneer in the field of nutrition. He conducted some of the very first experiments to show how the food we eat affects our health. He proved that a poor diet can lead to various diseases.
Diet and Disease Connection
McCarrison was the first to show through experiments how a lack of certain foods affects animal bodies and organs. He also did studies on people to find out what caused goitre. He even included himself in some of these experiments! Much of McCarrison's work was groundbreaking. His 1921 book, Studies in Deficiency Disease, was very important. It came out when scientists were just starting to understand vitamins and their role in our diet.
McCarrison pointed out that before his studies, no one had systematically checked the bodies of animals that ate food lacking in vitamin B. No one knew how such food affected different body systems. Most importantly, no one understood its effects on the stomach, intestines, and other digestive organs. He showed how important these effects were for doctors.
Founding Research Laboratories
At just 23 years old, McCarrison went to India. He spent 30 years there working on problems related to nutrition. He rose to the rank of major-general in the Indian Medical Service. He also founded the Nutritional Research Laboratories in Coonoor. After retiring in 1935, he gave a series of talks in London about how diet affects health.
These talks explained how our bodies use food. They also covered essential nutrients and how they relate to our body's structure and function. Finally, he discussed how to prevent diseases and improve our physical health through better eating habits. These talks were later published as a book called Nutrition and Health. Even 25 years later, the book was still considered relevant.
Studying Goitre and Health
McCarrison's work on goitre, cretinism (a condition caused by severe thyroid problems), and the thyroid gland began in the western Himalayas in 1902. This research led to many scientific papers over the next 35 years. While his work is often seen as the start of serious studies on goitre in South Asia, earlier research had been done by others.
In 1918, McCarrison started the Beri-Beri Enquiry Unit in a small lab in India. After a break due to illness, the unit was closed for a short time because of money issues. It reopened two years later as the Deficiency Disease Inquiry, which McCarrison led from 1925 to 1929. Around 1928-29, this grew into the Nutrition Research Laboratories (NRL). This lab was later renamed the National Institute of Nutrition in 1969. McCarrison was its first director until his retirement in 1935.
In 1926, McCarrison provided written and spoken evidence about malnutrition to a special commission on agriculture in India. He wanted to show how malnutrition caused poor health among many people in India. He also highlighted the link between nutrition and farming. He stressed the need for better teamwork between nutrition, medical, animal, and farming research in India. McCarrison's ideas had a big impact. Later, the chairman of the commission, Lord Linlithgow, became the leader of India. He took a personal interest in nutrition, making it a top research priority.
Life After India
After the Second World War, from 1945 to 1955, McCarrison worked at Oxford University. He was in charge of medical education for doctors who had already finished their basic training.
Personal Life
In 1906, Robert McCarrison married Helen Stella Johnston. They remained married until his death.
McCarrison's Legacy
McCarrison's work left a lasting impact on the world of nutrition and health.
- The National Institute of Nutrition in Hyderabad, India, still honors its beginnings in 1928 under McCarrison's leadership.
- McCarrison is seen as one of the founders of the organic agriculture movement. This movement focuses on growing food naturally, without artificial chemicals.
McCarrison Society
In 1966, a group of doctors, dentists, and veterinarians who cared about nutrition and health started the McCarrison Society. They did this to honor his efforts. A separate group was formed in Scotland in 1981 because of travel difficulties and different needs there.
The Society aims to gather scientific knowledge about nutrition and health. They want this knowledge to be free from money or political pressures. Their goal is to help future generations stay physically and mentally healthy. The society's meetings sometimes discuss difficult questions. Speakers present information that might be new or based on personal stories. Some people might criticize this, but the society's speakers are often very qualified. The main point is that the society asks important questions about our environment and how it affects us.
The journal "Nutrition and Health" is the official publication of the McCarrison Society. It publishes scientific articles and reviews on nutrition and health. These articles come from researchers who are not connected to the food or farming industries.
The society's website explains McCarrison's work like this:
His research was wide-ranging. It included studies on the newly found vitamins and on how diseases differed across the Indian subcontinent. He showed that many common diseases, which were becoming more common in industrial societies, were simply caused by diets made poor by lots of food processing. This often involved using chemical additives. He disliked that people in Britain and America ate refined white flour instead of halite flour. He also disliked that canned, preserved, and artificially sweetened products replaced fresh, natural food.
McCarrison's work was published widely in medical journals. He was honored for his discoveries. However, governments and the medical profession largely ignored him. At that time, medical thinking was more focused on treating diseases than on preventing them and promoting good health.
