Did you know that if you adopt a vegan diet you can enjoy better sex? Save money? Have glowing skin? You can ward off Alzheimer’s, Type 2 diabetes, rheumatoid arthritis, and other metabolic diseases. You can eat delicious burgers. Help save the planet. Join the cool kids, like Gandhi, Tolstoy, Leonardo—and Kyrie Irving, Kat Von D, and Joaquin Phoenix. Oh, and did we mention have better sex? (It’s about blood flow.)Those are just some of the 72 reasons we should all be vegan, as compiled and persuasively argued by Gene Stone and Kathy Freston, two of the leading voices in the ever-growing movement to eat a plant-based diet. While plenty of books tell you how to go vegan, 72 Reasons to Be Vegan is the book that tells you why. And it does so in a way that emphasizes not what you’d be giving up, but what you’d be gaining.
