How Blood Type Food Scoring Works

The blood type diet framework sorts foods into three categories for each blood type, based on the original theory.

Highly beneficial foods

Foods theorized to actively support health and digestion for a specific blood type, based on claimed ancestral dietary patterns.

Neutral foods

Foods considered fine in moderation, without strong theorized benefit or harm for that specific blood type.

Foods to avoid

Foods theorized to be harder to digest or process efficiently for a specific blood type, based on the theory's claims about digestive enzyme and stomach acid differences.
