What Is the Blood Type B Positive Diet?

The blood type diet was popularized by naturopathic physician Dr. Peter D’Adamo in his book Eat Right 4 Your Type.
The theory suggests that your ABO blood group reflects ancestral eating patterns: Type B, believed to have emerged among nomadic herders in the Himalayas and Ganges River region, aligns with a balanced omnivorous diet that includes meats, dairy, grains, and produce.
While the diet doesn’t differentiate significantly between B positive and B negative in food recommendations, the Rh factor (the “+” or “-“) is a protein on red blood cells unrelated to dietary needs.
So whether you’re B+ or B-, the food guidance remains consistent. The good news? Type B is considered the most flexible and adaptable blood type, able to enjoy a wide variety of foods.

Supplements Often Recommended for Type B
While food first is always best, some practitioners suggest these supplements for type B individuals:
- Magnesium: Supports energy production and muscle function
- Vitamin D: Important for immune function and bone health
- Probiotics: To support gut health, especially with dairy consumption
- Digestive enzymes: May help with protein breakdown and nutrient absorption
- Lecithin: Supports brain and liver function
Important: Always consult your doctor or a registered dietitian before starting supplements.
What Does Science Say About the Blood Type Diet?
It’s essential to address the evidence: A 2013 systematic review in the American Journal of Clinical Nutrition analyzed multiple studies and found no scientific proof that eating according to blood type improves health outcomes.
Another study noted that benefits people experience likely come from eating more whole foods and fewer processed items—not from blood type matching.
That said, the B positive diet’s emphasis on lean proteins, vegetables, fruits, whole grains, and healthy fats aligns with many evidence-based eating patterns.
The inclusion of dairy (which type B tolerates well per the theory) can provide calcium and probiotics. If this approach helps you make healthier choices consistently, that’s valuable—just don’t rely on blood type alone to dictate your nutrition.
