This title looks at why our ancestors relied so much on omega 3 oils, found in fish, flaxseed, game, breast milk and walnuts for their brain development and general health. The author believes most humans are deficient in omega 3 from birth onwards - especially if we're not breastfed. The results of deficiency include: depression, post-natal depression, an increase in degenerative diseases like Alzheiners, and an increase in heart attacks and strokes. This book introduces a safe, natural, and simple treatment for managing depression and related illnesses without side effects using diet and over-the-counter supplements.
