Why Vegans Have Smaller Brains: And How Cows Reverse Climate Change

Rate this book
A groundbreaking book that reveals why plant-based eating is not only harming human health, it is also harming the planet. The authors explain why a pasture-reared meat diet – the Sapiens diet – is more ethical and humane than a vegetarian or vegan diet.

With qualifications in medicine, nutrition, geology and agriculture, the authors bring together a unique combination of expertise in health, diet, earth sciences and the impact of farming systems on the environment.

This thought-provoking and topical book explains how we can prevent and reverse many chronic diseases by eating the diet that drove human evolution, a diet based on meat, animal fat and offal. The book also shows how crop farming is causing climate change, soil destruction, animal suffering and ecological disaster.

Why Vegans Have Smaller And How Cows Reverse Climate Change bridges the gap between pasture and plate in an accessible and engaging way.

Poor ratings of this book likely stem from the dogmatic beliefs related to modern dietary and climate propaganda. Read the book and download the references online to make a fair assessment.

While the title might be antagonizing to those that only eat plants, the real topic is why we should be eating meat. It's unfortunate that the propaganda continues regarding plant based diets when there is scientific evidence that suggests veganism is an unsafe and incomplete diet and meat provides bioavailable nutrients the human species needs to procreate and evolve. Even those who do eat meat can sympathize with the moral vegan, who want to save every cute animal, but as this book discusses there is a heavy loss of life when it comes to crop farming that vegans are unaware of. I would recommend this book to anyone who believes a plant based diet is superior, as it explains the benefits of a meat based diet vs the downfalls of a plant based diet with supporting information. This includes information about nutrition and the environmental impacts these diets have. This would make a wonderful gift to your doctor. This is a lengthy read but worthwhile for your own health. Please ignore the 1 star angry vegan ratings this book has.

It's so refreshing to see challenges to the old dogma! As a reformed vegan, I think this is such important information. Thank you!
