Complete Blood Type Diet Food List — What to Eat for O, A, B, AB

Understanding Blood Type Diet

The blood type diet is based on the idea that your blood type (O, A, B, or AB) determines which foods your body digests most efficiently. While scientific evidence remains mixed, many people report feeling better when eating foods aligned with their blood type.

Each blood type has a unique protein composition that reacts differently to lectins (proteins found in foods). By eating foods optimized for your blood type, you may experience better digestion, increased energy, and improved overall health.
