Why the China Study is Flawed
February 23, 2006
The China Study claims to be the most comprehensive study on nutrition ever conducted. It involved 65 counties in 24 different provinces of China.
Most of the counties were in rural areas where people lived in the same area all their lives and ate food produced locally.
Those living in rural communities and consuming mostly plant protein had fewer chronic diseases than those who lived in communities where more animal protein is available.
In rural China, 9-10 percent of total calories comes from protein, yet only 10 percent of that amount is derived from animal foods. In contrast, the American diet features 15-16 percent of calories from protein with 80 percent of that from animal foods.
The rural Chinese were less likely to die from the diseases of affluence (cancer, diabetes, and heart disease) than diseases of poverty (pneumonia, parasitic disease, tuberculosis, diseases associated with pregnancy, and others).
Dr. T. Colin Campbell says diseases of affluence might be more appropriately named "diseases of nutritional extravagance" because they are tied into eating habits.
