EXPERIMENT BY COLIN CAMPBELL (with rats) Aflatoxin causes liver cancer AF+diets containing 20% of protein: liver cancer AF+diets containing 5% of protein: no signs of liver cancer 6

How does protein intake affect cancer initiation? MFO: mixed function oxidase enzymes detoxifies and activates aflatoxin his activity could be modified by changing the level of protein intake 7

Cancer promotion Foci recursor clusters of cells that grow into tumors development was dependent on: how much protein was consumed regardless of how much aflatoxin was consumed 8

Conclusion to prevent cancer Eat less processed and red meat Eat more vegetables protein
