Audiocast #40 – Epigenetics
Humans, like most organisms on earth, grow and maintain their biological systems through a complex interplay between the environment and their genes. Epigenetics is the study of the ability of environmental signals to silence or activate these genes, thus effecting cellular function and species survival. I was once given an analogy, by Dr. Randy Jirtle, that your genes are like a computer hard drive. They do nothing until the software inputs change activity. The environmental signals like food, chemicals, stress and much more are the putative software inputs for us. Good lifestyle inputs have been epidemiologically proven to reduce disease risk.
