In "The China Study," written by Dr. T. Colin Campbell, he talks about the connections between nutrition and heart disease, diabetes, and cancer. The author also discusses the sources of dietary ambiguity, including powerful lobbyists, governmental organizations, and opportunistic scientists. The New York Times referred to the study as the "Grand Prix of epidemiology" and the "most comprehensive large study ever undertaken of the relationship between diet and the risk of developing disease." The China Study is not a nutrition guide. Anyone dealing with cancer, diabetes, heart disease, obesity, or those worried about the effects of aging will find Dr. Campbell's message insightful as she cuts through the fog of false information.
