Question
Is there any merit to the idea that people should eat and avoid certain foods according to their blood type?
Answer
No. The so-called "blood type diet" suggests different diets for different blood types based on the theory that each blood type interacts with foods in a unique way. However, there is no scientific evidence that shows the interaction between blood type and diet has any influence — positive or negative — on weight or overall health.
