The Cancer Casein Connection
In fact, the connection between casein and cancer was so profound that the scientists could literally turn cancer growth on and off in the laboratory animals, like a light switch, simply by altering the level of casein protein in their diets. Interestingly, they also found that feeding the animals the same levels of plant based protein (gluten and soy) did not at all promote cancer growth.
Next, Campbell was able to take his research into the real world. In the early 1980’s a joint effort was established between Cornell University, Oxford University and China’s health research laboratory. The researchers gathered data on 367 variables, across 65 counties in China and 6,500 adults. The research was conducted over a 10 year period and was funded by both the Chinese and the United States government.
The Cancer and Animal Protein Connection
The results of the China Study showed that nutrition has a very powerful influence on a multitude of diseases. Animal based foods were linked to higher breast cancer rates and higher blood cholesterol levels. Whereas plant based diets were connected to low incidents of breast cancer rates and cholesterol levels. Fiber and antioxidants from plant foods were also linked to lower levels of digestive tract cancers. Between Campbell’s research and many other studies, it appears that good science – well thought out and planned studies – are painting a consistent picture between diet and health. Because of this research we are now able to largely reduce our risk of developing deadly diseases just by eating the right food.
