Blueberries are one of the foods with the highest antioxidant value.  To boost the anti-oxidant value even more, eat organic blueberries, rather than commercially grown berries.  If you want to enjoy blueberries
year round you may freeze them, as they maintain their anti-oxidant value after being frozen for 3 to 6 months.  You will likely prefer to use them only in baking after freezing them, though, because the fleshy inside pulp loses its firmness after being frozen. 

Blueberries can be enjoyed by most people because they are also a low glycemic food, although blackberries, strawberries and raspberries are even lower on the glycemic scale.  Research has shown that eating 3 serving of low glycemic fruit per day improved blood sugar regulation.

Blueberries have been shown to improve neurologic function and to improve memory. Daily consumption of blueberries over the course of 3 months has been shown to increase eNOS, an enzyme that improves cardiovascular health, reducing blood pressure as well. 
Because of their antioxidant value, they are protective to the eyes and protective against certain kinds of cancers as well.

Blueberries make a colorful, healthy snack for kids too.  But check their noses and ears…kids have been known to hide them.
