LeAnne Campbell, PhD, lives in Durham, North Carolina. She has been preparing meals based on a whole-food, plant-based diet for almost 20 years. Campbell has raised two sons—Steven and Nelson, now 18 and 17—on this diet. As a working mother, she has found ways to prepare quick and easy meals without using animal products or adding fat.

For more than 40 years, T. Colin Campbell, PhD, has been at the forefront of nutrition research. His legacy, the China Study, is the most comprehensive study of health and nutrition ever conducted. Dr. Campbell is the Jacob Gould Schurman Professor Emeritus of Nutritional Biochemistry at Cornell University. He has received more than 70 grant years of peer-reviewed research funding and authored more than 300 research papers. The China Study was the culmination of a 20-year partnership of Cornell University, Oxford University and the Chinese Academy of Preventive Medicine.
