I just googled blueberry in search of a picture and it came back with "did you mean blackberry?" It made me laugh.
Blueberries have one of the highest antioxidant levels
They help prevent cancer
Great source of fiber (helps constipation)
Assist in decreasing stress
Build up minute retention skills
AND they make wonderful fingerfoods for our little bunnies. They're in season right now and would also be good in the cobbler that some of us are thinking of making for Valentine's Day.
