This book has started an optimum nutrition revolution around the world, from the UK to China, now in 30 languages selling more than 3 million copies. When I left the Institute for Optimum Nutrition at the turn of the century I wrote down everything I had learned in 20 years deep study into what optimum nutrition really is. it has since been updated. It’s the kind of book you lend to others, use as a resource, and gives you a great perpective on the whole field of nutrition and health above and beyond the fads that come and go. A great foundation for those who do care about their and their family’s health.
