Karen Vago & Lucy Degremont

Co-authors Karen Vago and Lucy Degremont have built on Peter D'Adamo's best selling "Eat Right for Your Type" to offer a range of over 100 recipes to suit each of the blood types.

Karen Vago and Lucy Degremont explain the theory that the four different blood groups, O, A, B and AB need four different diets. Their "Blood Type Diet Cookbook" includes an easy-to-follow plan, blood type food lists for each of the groups, and of course the recipes themselves.

Karen Vago and Lucy Degremont also explain how the different recipes can be adapted to suit the different blood types.

If you have always felt that you were eating the 'wrong' type of food for your system, you may want to check out this plan. According to the blood type diet, some of us need more meat and less grains, others should avoid dairy, and so on.

Though unsupported by conventional science, it has nonetheless worked for many people.
