The Devils Fat is a book everybody should read. The Omega Three and Six essential fatty acids families, (EFAs), are particularly fundamental to female health. Omega 6 is the sibling of Omega 3. If Omega 3 is the mistress, Omega 6 is the master. Omega 6 arguably links us to the fertility of the environment. The impact of EFAs on health, body structure, and function are little understood by the general public. Omega 3 and 6 alter behaviour. This book looks at pressing issues in society from an Omega 3 and 6 viewpoint including the impact of excess Omega 6 on health costs, for individuals and nations, in a competitive world. Issues examined include; western inflammatory conditions, such as ADHD, asthma, arthritis, diabetes, osteoporosis, and neurological disorders like dementia and Alzheimer's, as well as fertility, early puberty, obesity, sleep quality, gender identity, alcohol consumption, and behavioral trends such as aggression, self harm, suicide, and criminality. The book tries to be both understandable to the general public, and sufficiently authoritative to interest a doctor. Well over 800 references are made to trials and reports. There is no other book in the mainstream market that examines the importance of Omega 3 and 6 in human health, in such detail or breadth. A female librarian said the book was fascinating and difficult to put down. Another female reader said the central message was very clear, and was applied to everyday issues of interest. Robert Brown is a lay person. Robert had to understand the subject matter from scratch. He takes the reader on his search to understand the why EFAs are so important to health. The book contains a wealth of information. It is split into small indexed topic sections for browsing. There are no commercial links. Excess Omega 6 has more profound and wide spread impact than smoking. It is insidious. Most of us have no idea that excess Omega 6 is anything but good for us - we are told eat more polyunsaturates.
