They always have a and careful attitude when they deal with many things; People with type B blood are cheerful, and outgoing; People with type O blood are generous and honest; while those with type AB blood are often caring and helping.

    Last year, a doctor in the United States wrote a book that links blood types and what people eat. For example, his book gives some, like people with type O blood should eat more meat and less bread. A diet for people with type A blood includes more vegetables. His book, Eat Right for Your Type, has been a hit with people who want to lose weight. What's more, the book says eating food thata person's blood type can not only help them lose weight but also make them healthier.
