Diseases of Faulty Nutrition

By Sir Robert McCarrison, MD

Summary: Dr. Robert McCarrison is a bona fide giant in the history of nutrition. As a member of Britain’s Indian Medical Service in the early twentieth century, he conducted some of the first feeding studies investigating the effects of vitamin-deficient diets on test animals, and his 1921 book Studies in Deficiency Disease remains a classic on the physiological consequences of malnutrition. In this essay from 1928, Dr. McCarrison focuses on the “minor manifestations” (or, in today’s terms, subclinical symptoms) of vitamin deficiency, which he rightly names as harbingers of serious illness that any good doctor should be familiar with. He also admonishes his medical colleagues for fixating on bacteria as causes of disease, noting that it is malnutrition that sets the stage for infection in the first place. “Obsessed with the idea of the microbe,” he writes, “we often forget the most fundamental of all rules for the physician—that the right kind of food is the most important single factor in the promotion of health, and the wrong kind of food the most important single factor in the promotion of disease.” From Transactions of the Seventh Congress of the Far Eastern Association of Tropical Medicine, 1928.

Nutrition and National Health: The Cantor Lectures

By Sir Robert McCarrison, MD

Summary: In this in-depth lecture before the Royal Society of Arts, Dr. Robert McCarrison discusses conclusions and observations of his pioneering research as Britain’s former Director of Research on Nutrition in India and its implications for the health of Britain’s population. “The greatest single factor in the acquisition and maintenance of good health,” he says, “is perfectly constituted [i.e., whole, natural] food.” 1936.

Nutrition and Health

By Sir Robert McCarrison, MD

Summary: Dr. Robert McCarrison, the famed British nutrition researcher knighted for his work in India (which culminated in the classic reference Studies in Deficiency Disease), gives a lecture to London schoolchildren about diet and nutrition. He recounts his famous rat-feeding studies mimicking the diets of differing populations in India and, based on the results of his studies, gives his prescription for a basic healthful diet: freshly milled grains, raw milk and milk products, legumes, fresh vegetables, fruit, eggs, and meat. Reprint 43, 1937.

Medical Testament—Nutrition and Soil Fertility

By Sir Robert McCarrison, MD, and Sir Albert Howard

Summary: In 1911 Britain passed its National Insurance Act, a law intended to “provide for the prevention and cure of sickness” of its citizens. Yet despite the bill’s aim, rates of chronic disease proceeded to explode in the country over the ensuing decades. While medical officialdom was at a loss to explain or prevent the events, in 1939 the 600 family doctors of Cheshire county gathered to issue a public “testament” naming both the cause of the new epidemics and the means of their reversal. The physicians, reflecting on nearly three decades of clinical experience, named malnutrition at the hands of industrially processed foods as the common cause of chronic disease while marveling at the “amazing benefits” of switching patients to a diet of nutrient-dense, organic foods. Two researchers instrumental in guiding the doctors to their findings were Sir Robert McCarrison and Sir Albert Howard, both of whom were invited to speak at the famous Cheshire meeting, as recorded here. In their speeches McCarrison and Howard articulate the basic principles of what might be called “ecological nutrition,” that the health of humans depends on the health of the foods they eat, which in turn depends on the health of the soil those foods are grown in and on. With the medical industry still baffled by the cause and prevention of chronic disease, the words of these farsighted researchers offer a blueprint for building true health and wellness in humankind, literally from the ground up. Originally published in New English Weekly, 1939.

Nutrition in Health and Disease

By Sir Robert McCarrison, MD

Summary: In this 1936 article from the British Medical Journal, nutrition pioneer Sir Dr. Robert McCarrison lays out some of the basic principles of nutrition—principles that have long been lost by a modern world that has convinced itself that processed foods are sufficient substitutes for whole natural foods. In addition to the fundamental truth that only whole foods can properly nourish the body, McCarrison discusses specific dysfunctions that occur in the two body systems affected most immediately by a poor diet—the gastrointestinal tract and the endocrine system. From the British Medical Journal, 1936.

Studies in Deficiency Disease

By Sir Robert McCarrison, MD

Summary: The complete classic of 1921, as republished by the Lee Foundation for Nutritional Research in 1945. Dr. Robert McCarrison was knighted in England for his groundbreaking research while serving as a British army surgeon in India during the first two decades of the twentieth century. His landmark investigations into the connection between the diets of various populations in India and their patterns of disease and health gave new insight into the cause and effect of nutrition on health and introduced the world to the amazingly healthy and long-lived Hunza people of the Himalayas. McCarrison set up laboratories in which he studied the effect of various local diets on animals, reproducing nearly the same health and disease patterns in the animals as displayed in the particular populations. Diet, he concluded, was the determining factor in the specific health patterns of each population. McCarrison was also the first researcher to inform the medical world that the endocrine system is the first system in the body to succumb to the effects of malnutrition, carefully demonstrating the lesions in the endocrine glands caused by specific adulterated foods. His work inspired the likes of Royal Lee, Weston A. Price, Francis Pottenger, Jr., and J. I. Rodale. Still remarkably relevant today, this book should be part of the corpus of all colleges of the healing arts. Originally published by Oxford Medical Publications, 1921.
