THE ANSWER IS IN YOUR BLOODTYPE The book content explains the direct link between ABO blood types of people and diet, disease, longevity, and compatibility. It explains what one`s blood reveals about the person, why some people within a family stay healthy and others do not, how to add 20 healthier years to one`s life, why certain common foods are considered poisonous, and how to lose body fat without starving. It also contains menus that are blood type specific per individual, refuting the one-for-all-diet philosophy.
