Also called the biotype diet, the Blood Type diet was designed by author Dr. Peter D’Adamo, who outlined the program in his book "Eat Right for Your Type." On the plan, dieters eat certain foods deemed beneficial for their particular blood type 1. According to D’Adamo, food proteins called lectins are digested differently depending if you are a Blood Type A, B, AB or O. The B Blood Type person has more flexibility in her diet compared to O and A, but does best on a gluten-free diet.
Some of the sweeteners on the beneficial list for Blood Type B people include black strap molasses and real maple syrup. Honey is considered neutral, which means it’s not harmful, but doesn’t have any special nutritional properties that benefit Blood Type B. The natural sweetener stevia, as well as artificial sweeteners, should be avoided.
