Abstract
The information contained in DNA is not definitive, but modifiable. Indeed, the environment has the power to modify the genetic material expression without altering the DNA genes sequence. The principal environmental factors that work in this way, whether in a positive or in a negative way, are diet and stress with their ruling hormones, insulin and cortisol; these hormones are normally antagonists but, when they reach their respective resistances, they become the ubiquitary etiopathogenetic factors in bidirectional convergent relationship, each other causing the disinhibition and development of low grade systemic inflammation that opens the door to a myriad of interconnected sets of problems. Among these problems the greater one is cancer, which represents the extreme junction between hyperinsulinemia and hypercortisolemia, just because cancer cells never become insulin resistant and/or cortisol resistant.
