JOHN YUDKIN (1910–1995) was a British physiologist and nutritionist. He became internationally famous with his book Pure, White, and Deadly, first published in 1972, and was one of the first scientists to claim that sugar was a major cause of obesity and heart disease.

ROBERT H. LUSTIG, M.D., is the New York Times-bestselling author of Fat Chance: Beating the Odds Against Sugar, Processed Food, Obesity, and Disease. His YouTube video “Sugar: The Bitter Truth” has been viewed nearly three million times. An internationally renowned pediatric endocrinologist at the University of California, San Francisco, Lustig has spent more than fifteen years treating childhood obesity and studying the effects of sugar on the central nervous system, metabolism, and disease.

The classic exposé on the dangers of sugar, with a new introduction by Robert H. Lustig, the bestselling author of Fat Chance

Scientist John Yudkin was the first to sound the alarm about the excess of sugar in the diet of modern Americans. His classic exposé, Pure, White, and Deadly, clearly and engagingly describes how sugar is damaging our bodies, why we eat so much of it, and what we can do to stop. He explores the ins and out of sugar, from the different types—is brown sugar really better than white?—to how it is hidden inside our everyday foods, and how it is damaging our health.

In 1972, Yudkin was mostly ignored by the health industry and media, but the events of the last forty years have proven him spectacularly right. Yudkin’s insights are even more important and relevant now, with today’s record levels of obesity, than when they were first published. Brought up-to-date by childhood obesity expert Dr. Robert H. Lustig, this emphatic treatise on the hidden dangers of sugar is essential reading for anyone concerned about their health, the health of their children, and the wellbeing of modern society.
