The bestselling author and widely-respected physician, Dr Frank Ryan reveals new research that shows a daily dose of the omega-3 fatty acids found in fish oils can reduce our risk of mental decline - especially of dementia and Alzheimer's - by as much as 50 per cent. The first book to weigh up all the evidence about the effectiveness of omega-3s, "The Brain Food Diet" sets out up-to-the-minute scientific evidence - unknown to the public until now - that omega-3s reduce the risk of cognitive decline, Alzheimer's and depression.Written in layman's terms, the book is particularly relevant to the over 50s, but also explains the relevance of omega-3s to improving mental function at all stages of human development. Dr Ryan explains how they prevent heart attacks and strokes, gives useful tips on how to redress a dietary imbalance (for the first time ever showing the right balance of omega-3s with omega-6s), and describes the other ways in which we can all keep our brains healthy. With 800,000 people in the UK suffering from Alzheimer's and millions in premature mental decline, this is vital reading if a mental health epidemic is to be prevented.
