AB Positive Blood Type Diet: A Beginner’s Guide and Food List

The AB-positive blood type diet is a nutritional plan that suggests specific foods and lifestyle choices based on the AB+ blood type, rooted in the belief that blood type affects digestion and disease susceptibility. Scientifically, however, there’s limited evidence to support the idea that blood type should dictate diet.

The primary aim is to improve overall health by eating foods that are supposedly compatible with the AB+ blood type, such as tofu, seafood, and green vegetables. The concept gained traction in the mid-1990s, largely due to Dr. Peter D’Adamo’s book “Eat Right 4 Your Type.”

Dr. Peter D’Adamo is an awarded naturopathic physician, author, and researcher-educator. Despite its popularity, the diet lacks robust scientific validation. No peer-reviewed studies conclusively prove that this diet achieves its stated goals and the scientific community remains skeptical due to a lack of empirical evidence.

What can you eat? The AB+ blood type diet recommends foods like tofu, seafood, and certain dairy products while advising against consuming chicken, beef, and corn. Proponents suggest that individuals with AB+ blood type would benefit the most, but, again, there’s no definitive scientific consensus to recommend the diet for any specific group.

What is the AB Positive Blood Type Diet?

The AB-positive blood type diet is a dietary regimen that suggests individuals with AB+ blood should consume a mix of foods suitable for both A and B blood types. However, a study published in PLoS One in 2014 found that adherence to blood-type diets had no significant association with health outcomes based on an individual’s ABO genotype.

The purpose of the AB-positive blood type diet is to optimize health by tailoring a diet according to one’s AB+ blood type, aiming to reduce the risk of chronic diseases. The AB-positive blood type diet suggests a varied intake of foods, making it more sustainable than restrictive diets. However, the lack of scientific backing, as evidenced in a 2014 study, raises questions about its long-term effectiveness and sustainability.

Exercise is generally recommended alongside any diet for overall health, but the AB-positive blood type diet doesn’t specifically emphasize exercise. Experts are skeptical, as the scientific community has not widely accepted the concept of blood-type diets. Anecdotal evidence suggests that some people feel better on the diet, but this is subjective and not supported by rigorous scientific evidence.

How does the AB Positive Blood Type Diet work?

The AB-positive blood type diet suggests a mix of foods suitable for both A and B blood types, emphasizing tofu, seafood, and green vegetables. The AB-positive blood type diet claims to promote weight loss by tailoring food choices to your blood type, but this isn’t backed by science.

For vegetarians or vegans with AB-positive blood type, the diet suggests focusing on plant-based proteins like tofu and legumes. The diet recommends a balanced intake of protein and carbs for AB-positive athletes, but there’s no scientific proof that it enhances athletic performance.

The diet claims to improve gut health by recommending foods that are “compatible” with AB-positive blood type, as well as to help manage allergies by avoiding “trigger foods” specific to AB-positive blood type. The diet also suggests that following it can improve mental clarity and mood for AB-positive individuals, but this is anecdotal.

In terms of muscle gain, the AB-positive blood type diet does not provide specific guidelines or recommendations tailored toward this goal. However, a balanced diet that includes adequate protein, carbohydrates, and healthy fats, combined with regular resistance training exercises, is generally recommended for muscle gain.
