![]() 1 When originally released, the book was met with a combination of praise and criticism and became the subject of many a research study in the years since its publication. These factors and more were the basis for the 1996 book (updated and revised in 2016) Eat Right for Your Type: 4 Blood Types, 4 Diets by Dr. In our articles on blood type A, blood type B, and blood type AB*, we examined various components of these blood type profiles - their approach to exercise, what foods are recommended as best to eat, for what diseases or conditions might they uniquely be at risk, and what can be done to abate those risk factors. It creates an immune response that leads to the production of antibodies (proteins that bind to foreign invaders in the body). An antigen is a molecule that’s introduced to or is unknown to the body and may even be considered a toxin. When an O is also Rh-negative (more on this below), they can donate blood to any blood type and are therefore considered a “universal donor.”įree download: Get the Body Ecology blood type ebook. Lacking an A or B antigen, you are classified as blood type O (positive or negative). The type of antigen found on the surface of red blood cells (antigen A or B) is the factor that determines how a blood type will be classified. Mean total cholesterol decreased 17.2 mg/dl in the type A group and 18.3 mg/dl for non-A participants, and decreased 17.4 mg/dl among type O participants and 18.4 mg/dl for non-O participants.Blood type Os tend to be bold, sociable self-starters. 5.7 kg for blood type A participants and -7.0 kg for non-A participants, and was -7.1 kg for type O participants and -6.2 kg for non-O participants. There were no significant differences in any outcome between individuals of blood type A and non-A, or between individuals of blood type O and non-O. T-tests compared participants with blood type A to all other participants (non-A), and individuals with blood type O to all other participants (non-O). Main outcomes that were measured were body weight, fat mass, visceral fat volume, blood lipids, fasting plasma glucose, and HbA1c. “Our research shows that all blood types benefit equally from a vegan diet based on the consumption of fruits and vegetables, legumes and whole grains, looking specifically at weight loss and cardiometabolic health in overweight adults,” he says. “While the blood type diet says that a plant-based diet should be better for blood type A and less so for blood type O, it turned out to be beneficial for people of all blood types, and there was no evidence that meaty diets are good for anyone. “We found that blood type made no difference,” says study author Neal Barnard, MD, president of the Physicians Committee. They considered whether the effects of a plant-based dietary intervention on body weight, blood lipids, and glycemic control are associated with ABO blood type. The “blood type diet” recommends a mainly plant-based diet for those with blood type A, while it recommends a diet heavy in meat for people with blood type O. To consider a potential connection between blood type and diet, researchers took the additional step of conducting a secondary analysis among intervention-group participants of the 16-week randomized clinical trial. The key finding is that a plant-based diet ramps up metabolism as measured by an increase in after-meal calorie burn of 18.7%, on average, for the intervention group over the control. Participants in the intervention group followed a low-fat, plant-based diet. 30. That trial randomly assigned overweight participants with no history of diabetes to an intervention or control group on a 1:1 ratio for 16 weeks. This new study is based on a randomized control trial whose main findings were published in JAMA Network Open on Nov. WASHINGTON-A study published in the Journal of the Academy of Nutrition and Dietetics by researchers with the Physicians Committee for Responsible Medicine-a nonprofit of 12,000 doctors-debunks the “blood type diet” by finding that blood type was not associated with the effects of a plant-based diet on body weight, body fat, plasma lipid concentrations, or glycemic control.
