After following a vegetarian diet for years, Natalie switched to a vegan diet after reading the book Eating Animals. In an interview with Vanity Fair, she said, “When I read the book, that was what made me become a vegan. I think until then, I had thought, Oh, with eggs and dairy, you’re not [harming] animals. It’s just their natural byproducts. But when I started learning about the conditions and the environmental effect of all these animals and the impact on humans of having large groups of sick animals together, it really made me want to change immediately.”
