About this collection
Our Blood Type Diet section covers Peter D'Adamo's blood-type-based eating framework with printable food lists for Type O, Type A, and Type B, foods to avoid on each type, and a review of what the published science actually shows about blood type and diet response.
Every food list is cross-checked against the Nutritionix database and USDA references so calories, protein, iron, and fiber on a sample day reconcile to the gram. Where the Blood Type Diet framework overlaps with mainstream nutrition (more vegetables, less ultra-processed food, moderate portions), we say so. Where it makes claims that do not hold up in randomized trials, we say that too and cite the evidence rather than talk around it.
Blood Type Diet content is written or reviewed by our Registered Dietitians Brenda Peralta, Kerly Cordova, Marita Radloff, and Karolina Peterova, and medically reviewed by Franco Cuevas, MD, so readers can weigh the framework honestly against what randomized controlled trials have found on adherence, weight loss, and cardiometabolic markers.
