Blood type diet: perception in disease prevention

The Blood Type Diet proposes that the foods consumed should be tailored to one’s blood type, which is believed to correspond to the dietary habits of respective ancestors, thus serving as a nutritional approach. The review investigates the perceptions surrounding the role of blood type diet in disease prevention, emphasizing its relevance to common health conditions such as obesity, diabetes mellitus, cardiovascular disease, cancer, ulcers, gynecological disorders and allergies, elucidating how dietary choices based on blood type may impact outcomes of a medical condition. For individuals with Type O blood group, a high protein, low carbohydrate diet is advised, potentially mitigating risks of thyroid disorders, peptic ulcers and inflammatory conditions. Conversely, type A individuals are steered towards a predominantly vegetarian diet to manage cardiovascular disorders and blood viscosity. People with type B are encouraged to encompass a comprehensive range of foods into their diet, paying attention to their lectin sensitivity and concerns regarding nutrient absorption. Type AB are recommended to adopt a blended diet, considering an immune response and gut microbiome dysbiosis. Further research in this realm holds promise for unraveling the fundamental mechanisms and refining dietary recommendations aligned with individual blood types, thus advancing personalized approaches to healthcare and promoting overall wellness.
