Elementary. For new and aspiring vegans. But presents veganism as more complicated than it needs to be. Emphasizes compassion for animals, but one need not be an animal lover to adopt this diet and lifestyle. Some discussion of the health benefits for humans. Rates vegetables above fruits. But we humans are frugivores who should regard fruits as the very foundations of our diets. See my essay called “What Should We Eat?” on my profile page.
This book does not go far enough, in my opinion. It recommends, or at least condones, too many foods that I consider objectionable, or even harmful. Foods such as soybeans, alfalfa, sea salt, garlic, mushrooms, mock meats, etc. Not everything vegan is good for you. Garlic and salt are toxic, including sea salt. Mushrooms too, probably. Salt is not even food, as it is indigestible. A good diet should go farther than this. And real vegans don’t eat mock meats! Well OK, maybe in transition. Lots of vegan recipes here; most contain ingredients I don't agree with. Recipes are unnecessary complications anyway.
For food fans in transition, but read it critically!
