This is the first time I’m hearing about this but it makes sense!

The scientific basis for the Blood Type Diet is still debated within the scientific community. Dr. D’Adamo suggests that the different antigens in each blood type react uniquely with certain nutrients, thus specific foods can either be beneficial or harmful depending on one’s blood type. Lectins, a type of protein found in foods, are said to bind differently with the antigens in each blood type, affecting digestion and health. However, comprehensive scientific evidence validating these claims remains limited, and the theory is often viewed with skepticism by many researchers.

Individuals with blood type A are believed to thrive on a vegetarian diet. Recommended foods for this blood type include vegetables, fruits, tofu, seafood, grains, beans, legumes, and minimal dairy. Avoided foods include meat, especially red meat, dairy products, kidney beans, lima beans, and certain wheat products. The theory suggests that type A individuals have a more sensitive immune system and lower stomach acid, making plant-based foods easier to digest and metabolize.

People with blood type B are thought to have a more balanced immune system and tolerate a diverse diet. Recommended foods include green vegetables, eggs, certain meats like lamb and goat, low-fat dairy, and specific grains. Foods to avoid are chicken, corn, wheat, lentils, peanuts, and tomatoes. The diet suggests that type B individuals should focus on foods that enhance metabolic function and maintain a healthy gut.

Blood type AB individuals are advised to follow a diet that combines elements of both type A and type B guidelines due to their possession of both A and B antigens. Recommended foods include tofu, seafood, dairy, green vegetables, and certain grains like quinoa and brown rice. Avoided foods are chicken, corn, buckwheat, and kidney beans. This diet emphasizes foods that support the complex immune system and digestive needs associated with having both A and B antigens.
