The Sugar Fix stakes out new territory in the crowded field of dietary advice. But it is more than just another weight-reduction tutorial; it is a roadmap to better health.... Dr. Rick Johnson and Tim Gower bring to us the benefit of a rich understanding of the science of fructose and its fellow traveler, uric acid. They apply this knowledge skillfully in the design of a new and palatable way to reverse a long-standing obstacle to good health.
Richard J. Glassock, MD, professor emeritus of medicine, David Geffen School of Medicine, UCLA
Provocative, compelling, and a challenge to some of the classic paradigms... Dr. Johnsons case against fructose should stimulate much discussion and debate among scientists and the lay public alike.
James O. Hill, PhD, director of the Center for Human Nutrition, University of Colorado Health Sciences Center
Dr. Rick Johnsons new book provides compelling scientific evidence linking the current epidemic of obesity and diabetes with the progressive rise in fructose consumption over the last century, and particularly over the last 30 to 40 years. More significantly, the book provides a detailed plan for reducing dietary fructose intake, promoting weight loss, and reversing many of the serious health consequences associated with the typical American high-fructose diet.
Michael W. Rich, MD, professor of medicine and director of the Cardiac Rapid Evaluation Unit, Washington University School of Medicine
The Sugar Fix presents a combination of scientific research (the majority of it generated in Dr. Rick Johnsons laboratory), epidemiologic evidence, and historical insights, all linked together in the manner of a masterful closing argument before the jury retires for deliberation.... I have followed Dr. Johnsons travels along the fructose/uric acid pathway for years, and I am very happy to see the results of the journey in this book.
Dr. Bernardo Rodrguez-Iturbe, president-elect of the International Society of Nephrology and international expert on hypertension and kidney disease

Finally, I would like to thank my wife and children for their patience and support, and my patientsit has been a privilege and pleasure to treat and care for you.
INTRODUCTION
Dr. Chens Observation
It had been a long day, but I was in the mood to celebrate. I had learned earlier in the week that an important scientific journal, the Journal of Clinical Investigation (JCI), planned to publish a paper I had written based on my research. For a young scientist, this represented a major step toward gaining a full professorship at the University of Washington, where I worked at the time.
The future suddenly looked bright, so I accepted an invitation to a cocktail party at my bosss home. Soon after arriving at his lovely houseboat on Seattles Lake Union, one of my colleagues, Dr. Yipu Chen, approached me. Yipu, a visiting scientist from Beijing, greeted me with his usual enthusiasm and said, Rick, I believe you are going to be a professor some day. Yes, you will be a professor.
Thanks, I responded, beaming with pride. I assumed that Yipu was about to compliment me on my JCI paper. I didnt want to seem presumptuous, however. So I asked, Why do you think that?
Yipu smiled. Because you are getting fat, Rick, he said, patting my belly. And in China, only the professors get fat.
I recalled this scene when I set out to write this book for several reasons. For starters, I know what its like to struggle with extra weight now and then. After Yipu made his good-natured jibe, I slipped away to the bathroom and looked in the mirror. He was rightI
