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

Rate this book
A provocative and timely book that questions current thinking about diet, health and the environment. The authors challenge the ideas that meat is bad and plant-based is good, and that livestock farming is causing climate change.

An Oxford University study found that the less animal food you eat, the more your brain shrinks (atrophies) with age. Brain scans from breast-fed babies of vegan mothers also show brain atrophy, owing to deficiency of vitamin B12. This vitamin, which is vital for normal brain health, is not found in any plant food.

Many people have become resigned to the idea that heart disease, cancer, Alzheimer’s or another degenerative disease will kill them. This book shows that these illnesses were not our fate in pre-history and they need not be our destiny in the future. It explains how we can prevent and reverse chronic disease by eating the diet that drove human evolution, a diet based on meat, animal fat and offal.

What about the other reasons to eat meat? Readers will discover that plant-based eating is not only harming human health, it is also harming the planet. The authors show how crop farming is causing climate change, soil destruction, and ecological disaster. The flawed logic that we should replace meat with plant foods means that environmental destruction will continue, along with the socio-economic costs of diet-related disease. In contrast, regeneratively-grazed livestock mitigate climate change, enrich soils, support wildlife and provide nutritious food. This book firmly anchors the health benefits of an all-meat diet with farming and the environment.

Written in an accessible and engaging way, this book will appeal to everyone interested in diet, health, evolution and the environment.

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!
