Nutrition genetics is the science that studies how compounds in the food travels to the deepest celular level, alter your DNA and trigger a response from the cell.
This can be a good response such as when resveratrol (the phytonutrient in red grapes) activates the “longevity” in your cells. Or this can be a negative response, such as refined sugar, which binds to the cell and triggers the release of irritating chemicals that cause swelling and autoimmune conditions.
