Blueberries have the highest ranking of any fruit when it comes to their antioxidant content. This makes them potential cancer-fighters. Their antioxidant content also boosts your immune system so that you’re not as prone to nasty things like colds. Blueberries have also been shown to reduce belly fat and to reduce the risk of cardiovascular disease, although research is still ongoing. The b-complex, zinc, magnesium and other nutrients in blueberries are also thought to keep the memory sharp.
When buying fresh blueberries, I always look for those that are firm and that have a uniform color. I always shake the container that they are packaged in. If they move around freely, they are good. If they don’t, they may be too soft or old. Berries with a dull color wont’ last long.
When I buy pre-packaged frozen blueberries, I always give the bag a “test shake”. If the berries are all clumped together in the bag, that’s a good sign that they were thawed at one point and then refrozen, this is definitely not a sign of good product.
So, back to frozen blueberries, one of my favorite treats! When I freeze blueberries, I always remove any stems and leaves from them. I like to freeze them first on a tray. Once they are frozen, I pack them into a freezer-safe container, seal it and return to the freezer.
Frozen blueberries are great on yogurt (especially fage!), in salads, in smoothies, and even alone as a very sweet and filling snack. But, I don't recommend eating them with your fingers, unless you don't mind if they turn temporarily blue. :)
