The reason animal proteins trigger the release of the cancer-promoting growth hormone IGF-1 more than plant proteins may be because the relative ratios of amino acids in animal proteins more closely resembles our own.
Animal protein consumption triggers the release of the cancer-promoting growth hormone IGF-1.
Those eating vegan had significantly lower IGF-1 levels and higher IGF-binding proteins than those just eating vegetarian, suggesting that the more plant-based one’s diet becomes, the lower one’s risk of fueling growth hormone-dependent cancer growth.
Lower cancer rates among those eating a plant-based diet may be a result of reduced blood levels of IGF-1, and enhanced production of IGF-1 binding protein.
Congenital IGF-1 deficiency can lead to Laron Syndrome (a type of dwarfism); but with such low growth hormone levels, those with the condition have dramatically lower cancer rates. This raises the question of whether one can achieve the best of both worlds—by ensuring adequate IGF-1 levels during childhood, while then suppressing excess growth promotion in adulthood.
Insulin-like growth factor (IGF-1) is a natural human growth hormone instrumental in normal growth during childhood, but in adulthood can promote abnormal growth—the proliferation, spread (metastasis), and invasion of cancer.
Lifestyle medicine pioneer Nathan Pritikin, who reversed his own heart disease through diet and went on to help millions of others, wasn’t a doctor or dietician, but an engineer.
