DEEP NUTRITION revolutionises the way we think about food by establishing the direct link between our DNA and what we eat. Dr. Shanahan underlines why honouring the dietary traditions of our ancestors is so crucial if we wish to live longer, healthier and more vital lives. In particular, this book draws our attention back to the debate on healthy fat and the fundamental role it plays in improving and sustaining health. With case studies illustrating how this approach (called the Human Diet) can help improve mental health, calm allergies, boost fertility, eliminate cravings, sharpen cognition, improve memory, rejuvenate skin, build stronger bones and joints among others and go on to help us achieve optimum health.
