Protein Type and Cancer Response


A Clip from The China Study by T. Colin Campbell

‘..We also examined whether soy protein had the same effect on cancer development as animal protein.  It did not.  It responded the same as plant protein.  We had discovered that low protein intake reduces cancer initiation and works in multiple synchronous ways.  As if that weren’t enough, we were finding that high protein intake, promotes cancer after initiation.  Like flipping a light switch on and off, we could control cancer promotion merely by changing levels of protein, regardless of initial carcinogen exposure.  But the cancer promoting factor in this case was cow’s milk protein.

Thus far we had relied on experiments where we only measured  the early indicators of tumor development.  Now it was time to do the big study, the one where we would measure complete tumor formation.  We organized this and examined tumor formation over the lifetime.

The effects of protein feeding on tumor development were nothing less than spectacular.  All rats that were administered 20% levels of casein (cow’s milk protein) were dead or near death from the tumors at 100 weeks.  All administered the same level of carcinogen but fed the low 5% protein were alive, active and thrifty.  This was a virtual 100 to 0 score, something almost never seen in research..’

    These are pretty scary facts and really good to know. It is very sad that people are not given this information right at the doctor and/or specialist offices. Thank you for all your facts and beneficial information.

    • The China Study is powerful information. It is truly important for us each to do our research and be the biggest advocates for our own health. I’ve repeated this quote a couple times lately, but in the movie Forks Over Knives there was a saying shown ‘1/3 of what you eat feeds you, 2/3 of what you eat feeds your doctor’.

  2. Quite interesting study. I have to read the associated paper.
