2. Cancer and red meat Consumer of red meat: 30% risk

5. Hot Dog and cancer Nitrites carcinogens cancer of the: stomach bladder
esophagus
brain

6. 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

7. 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

8. 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

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