All foods are good for you in moderation.
Your blood type has nothing to do with what you eat. Bananas are good for people with low potassium levels in their blood, but that's not a blood type.
eggs
minerals
god knows.....
Since some food from each food group is necessary for good nutrition, there is no "best" food group.

Grains/carbohydrates.
Blood group A can donate and receive blood from blood group A. Blood group B can donate and receive blood from blood group B.
