Michelle Pfeiffer

Michelle Pfeiffer, whose family has a history of cancer, said a light bulb when on when she watched the CNN documentary The Last Heart Attack. She gave herself eight weeks to work towards a plant-based diet. In 2016, she told Urbanette.com: "Eating a vegan diet — it’s just so much healthier — and you avoid a lot of toxins that could age your skin and your body. I really noticed a difference in my skin not too long after switching to fully vegan. All I needed to eat are fruits and vegetables to stay lean."
