It’s not just about the rats


The other day someone said, “The book The China Study could be relevant except the diet only works on rats.”

The rat reference relates to an obscure scientific experiment Dr. Campbell found in 1970 from India (pg. 36-37). Two groups of rats were both infected with a fungus-produced toxin nicknamed AF (aflatoxin) which produced liver cancer in rats. One group of rats was fed a diet of 20% protein and the second group of rats ate a diet of no more than 5% protein. Every rat on the 20% protein diet developed liver cancer while NOT ONE rat on the 5% protein diet developed neither liver cancer or signs of beginning cancer development.

This one experiment became a turning point for Dr. Campbell and his research on the human need for protein in our diet.

It is not just the rats. Dr. T. Colin Campbell authored more than 300 research papers. The China Study was the result of work among Cornell University, Oxford University, and the Chinese Academy of Preventative Medicine. Work included studies mandated by past China premier Chou EnLai in the early 1970s involving over 650,000 people (pg. 69, 70).

Dr. Campbell worked on investigation of Philippine children’s incidence of liver cancer due to AF, a study of 800 Chinese women on bone density and osteoporosis (pg. 20-22).

The short story of The China Study is both the highest incidence of death in America (heart disease, cancer, stroke, diabetes, and Alzheimer’s disease) as well as the most expensive chronic ailments are largely prevented with a plant-based diet (pg. 20-22).

Even though Dr. Campbell’s research began with a protein study of rats’ diets, and he continued studying the effect of diet on rats, his numerous studies, meta-analysis (collection of other studies), and studies of homogeneous populations such as China more than prove the importance of plant-based diet to reduce the number of illnesses, increase our longevity and quality of life.
