This book was published in 1999 and though the information about Omega 3 oil has been around for awhile now, I leaned quite a bit of information I hadn't known about omega 3 oils. In fact, The Omega Diet has so much useful information, even vegetarians can take away lots of useful information. I was also impressed with the Fatty Acid Primer and with the clinical studies that demonstrated positive effects of omega 3 oils. The Omega Diet has lots of scientific studies backing it. The list of greens with Omega 3 oils and the baking tips for using flax meal and flaxseeds also make this book a useful reference book for any kitchen. The recipes in this book all have nutritional value charts that include LA, LNA, EPA, DHA and the Omega 6-Omega 3 ratio. A number of the recipes are vegan which gives this book a wider audience than the usual meat hungry diet crowd. The only part of the book I wasn't crazy about was the menu plans. Menus, in my opinion, are wasted paper in cookbooks.
