Should people with negative or positive blood types eat a special diet?

No scientific evidence supports the claim that people with different blood types should follow specific diets. Blood type does not determine nutritional requirements or predispose individuals to particular food sensitivities or health conditions. A balanced diet rich in whole foods, fruits, vegetables, lean proteins, and healthy fats is recommended for optimal health, regardless of blood type. Consult a registered dietitian or healthcare professional for personalized dietary advice based on individual needs and health goals.
