Probably not. Although there are some books and websites that tell you to eat based on your diet we are not aware of any current scientific evidence that shows that it matters. In some studies, for example, there was evidence that people who ate healthy foods and had blood type A had improved health, but so did all the other blood types in the study.

Overall the most reasonable advice is probably to just eat healthy generally, including avoiding excess empty carbohydrates like sugars.
