What Is the B+ Blood Type Diet?

Developed by naturopath Dr Peter D’Adamo, the blood type diet suggests that each blood group (A, B, AB, and O) has unique evolutionary traits and dietary needs. According to this theory, eating in line with your blood group helps your body function more efficiently, supports immunity, and reduces the risk of chronic diseases.

The B+ blood type diet is designed around the idea that people with blood type B positive may benefit from a balanced diet that includes dairy products, selected meats, vegetables, fruits, and moderate amounts of grains. According to this approach, eating foods that suit your blood group may support digestion, energy levels, and immunity. While scientific evidence is limited, many people interested in personalised nutrition explore the B+ blood type diet as a structured way to make healthier food choices.

While the science remains debated, many people find benefits when following tailored food plans that align with their body's needs.

B+ Blood Type Facts: Characteristics, Diet & Health

Understanding B+ blood type facts can help explain why this diet has become popular among some health-conscious individuals. According to the blood type diet theory, people with blood type B positive are considered adaptable and are believed to tolerate a wider variety of foods than many other blood groups. A balanced intake of dairy, lean proteins, vegetables, fruits, and whole grains forms the foundation of the recommended eating pattern for the B+ blood type, although individual nutritional needs may vary. 

Unlike other groups (like type O, which avoids dairy), the B blood type diet allows a broader range of foods. However, there are still specific items considered beneficial, neutral, or harmful.
