This is an incredibly short book bestowing the virtues of veganism, for not only individual health, but also, as a society, to the animals and to the planet.
Whilst I don't fault the research, as clearly from the references at the back of the book, this is heavily researched.
My criticisms are levelled at the opinions and the moralistic tones, as well the repetitions. Further, whilst I agree going vegan, is the more sustainable option, B12 and Omega 3 supplements are required in order to be 100% healthy. For me, this therefore negates the message droned in that a vegan diet can supply every required nutrient, taking vitamin supplements is not a healthy diet.
Further, the black and white viewpoint of veganism was off-putting. Whilst I am headed in a more plant based diet, and moving away from a predominantly meat heavy diet; this book at times made me want to eat a steak, just for how patronizing the tone is.
The stars are for the research, and not the authors' opinion. This book would of benefitted from a more scientific view point rather than the moralistic patronizing tone of the author.
