![]() ![]() The development of the ABO blood group system has had a great impact on different branches of science throughout the world. All about Os: Breaking down diet, exercise & personality 2 There doesn’t appear to be a high correlation between blood-type-specific diets and overall health as far as available research is concerned. That said, science has determined that blood type may play a role in the genesis of some disease states - and to a lesser degree, optimal exercise prescriptions and emotional strength. There’s not much in the medical literature confirming some of D ’Adamo’s assertions. 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. ![]() Ohio State University Wexner Medical Center.Blood type Os tend to be bold, sociable self-starters.

Health claims made by the blood type diet should be viewed as theoretical and not supported by scientific evidence. Evidence does not support using blood type as a basis for determining what foods to eat or avoid.The type O diet recommendations (emphasizing meat, fruits, and vegetables and limiting grains) have been associated with lower triglyceride levels, regardless of the person's blood type.Regardless of blood type, those whose eating patterns are similar to those outlined for the type A blood group (more fruit, vegetables, and grain, less meat) tend to have better cardio-metabolic (cardiovascular and metabolic) outcomes, such as lower body mass index (BMI), waist circumference, serum cholesterol and triglyceride levels (fats in the blood), and insulin resistance (when cells in the body don't respond well to the hormone insulin and have difficulty taking up glucose from the blood, requiring more insulin). ![]() Health outcomes from the foods recommended for each blood type are related to the foods eaten, not the blood type, and are not unique to any blood type.The main findings of existing studies examining the influence of blood type on diet and health benefits include: There is a lack of high-quality studies published in peer-reviewed medical literature on the blood type diet. ![]()
