"Our biology is no longer our destiny. In this newly expanded and updated book, world-renowned integrative medicine pioneer and bestselling author Dr. Kenneth R. Pelletier reveals the new frontier of personalized medicine and steps each of us can take to change our genetic expression for a lifetime of vitality and longevity. We now understand that our inherited DNA does not rigidly determine our health and disease prospects as geneticists once believed. In fact, scientists have confirmed that the vast majority of our genes are actually fluid and dynamic! An endless supply of new studies prove that our health is an expression of how we live our lives, what we eat, how we process thoughts, manage our daily stress, and shield ourselves from the toxicity of our immediate environment creates an internal biochemistry which has the ability to turn genes on or off. This era of epigenetics provides new avenues of prevention, treatment and reversals of heart disease, intestinal disorders, cancer, arthritis, stress conditions, as well as Alzheimer's disease. Managing these biochemical effects on our genome is the new key to radiant wellness and healthy longevity. State-of-the-art technology now constructs precise, high-tech genomic assays that provide highly detailed personalized profiles to guide our health choices. Genomic data, combined with microbiome assessments, will soon analyze trillions of gut bacteria for markers of epigenetic influence."-- from publisher.
