The China Study by Thomas Campbell

TURNING OFF CANCER 61

The effects of protein feeding on tumor development were nothing
less than spectacular. Rats generally live for about two years, thus the
study was 100 weeks in length. All animals that were administered afla-
toxin and fed the regular 20% levels of casein either were dead or near
death from liver tumors at 100 weeks.^36.^43 All animals administered the
same level of aflatoxin but fed the low 5% protein diet were alive, active
and thrifty, with sleek hair coats at 100 weeks. This was a virtual 100 to
o score, something almost never seen in research and almost identical
to the original research in India.^16
In this same experiment, 36 we switched the diets of some rats at either
forty or sixty weeks, to again investigate the reversibility of cancer pro-
motion. Animals switched from a high-protein to a low-protein diet had
significantly less tumor growth (35°tb-40% less!) than animals fed a high-
protein diet. Animals switched from a low-protein diet to a high-protein
