Experimental studies show that all thermolyzed (ultra-heated) proteins can promote colon cancer and so do thermolyzed carbohydrates and fried fat.
Thermolyzed casein in particular has shown to cause the growth of aberrant crypt foci (ACF tumors) and colon cancer.
Ultra-heating makes proteins less digestible as a consequence of cross-linking and racemization – which involve formation of unnatural peptides and amino acids.
As a result of decreased digestibility, more proteins escape from the stomach to the large bowel, where they’re fermented into tumor promoting waste products such as ammonia and a variety of toxic phenols.
