Diabetes, heart diseases and obesity are almost entirely induced by environmental and lifestyle factors. Predisposing genes certainly contribute, but those genes get turned on (or “expressed”) only under conditions of poor diet, sedentary lifestyle, stress, and exposure to environmental toxins.
The genetic code itself doesn’t change, but which parts of this code are expressed does change. This becomes a powerful idea: We can’t change our genes, but we can change their function and expression. The collective experience of our lives… our intrauterine environment, diet, toxins, microbes, allergens, stresses, social connections, thoughts, and beliefs….control which genes are turned on or off.
