When you eat a healthy, whole foods, plant-based diet, it changes the expression of your genes. It turns on the good genes, turns off the bad genes. Your genes are a predisposition, but your genes are not your fate. And even if your mother and your father and aunts and uncles all died of diabetes, cancer, even heart disease, it doesn't mean that you need to.

— Dean Ornish Interview in the documentary-film The Game Changers by Louie Psihoyos (2018)
