At the end of the 16 weeks, the researchers found no major differences in cardiometabolic changes between any of the groups. Lastly, in a 2020 study, 68 participants of different blood types ate a low fat vegan diet for 16 weeks.

Similarly, a 2018 study of 973 adults with overweight found that matching a participant’s blood type with the respective recommended BTD didn’t impact the link between BTD and markers of cardiometabolic disease. However, this effect was seen in everyone following the type A diet, not just individuals with type A blood. In a 2014 study of 1,455 participants, eating a type A diet of fruits and vegetables was associated with better health markers. D’Adamo’s claims that specific foods may cause benefits or harm to certain blood groups. The minimal research that does exist on BTD doesn’t support Dr. However, no studies suggest that these are related to diet. Research on ABO blood types has advanced rapidly in the past few decades.įor example, the authors of a 2022 study cite many associations that have been made between blood types and various diseases, such as: The health benefits may simply be a result of eating healthier food than before. So, even if you try one of these diets and your health improves, it doesn’t necessarily mean that it has to do with your blood type. This means that lectins in the diet may not be blood-type specific, except for a few varieties of raw legumes.Īll four diets are mostly based on real, healthy foods, rather than processed foods. Overall, however, it appears that the majority of agglutinating lectins react with all ABO blood types. For example, a 2004 review suggests that raw lima beans may affect red blood cells in people with blood type A. Some research suggests that a small percentage of lectins in raw, uncooked legumes can have agglutinating activity specific to a certain blood type.

They may cause red blood cells to agglutinate, or clump together, which could increase your risk of disease. Plant-based lectins are sometimes referred to as antinutrients and may cause negative effects in humans, such as:Īccording to the BTD theory, eating the wrong types of lectins may specifically target different ABO blood types. These are a family of proteins that can bind to carbohydrate molecules. One of the central theories of the BTD has to do with proteins called lectins.
