Benefits of Blueberries


Many berries are sweetened with sugars to make them palatable but blueberries are naturally sweet and juicy when fully ripe. The flavor of blueberries ranges from mildly sweet to tart (sour) and tangy. Blueberries are best when eaten fresh or frozen, not cooked or processed because cooking destroys vitamin C, eating blueberries raw preserves its antioxidant content. Blueberries are at their best from May through October when they are in season. Blueberries can be added to muffins, fruit salads, yogurt and jams.

  • Anthocyanins, the blue-red pigments that give blueberries its color can help enhance the effects of vitamin C, improve capillary integrity, and stabilize the collagen matrix (the ground substance of all body tissues).
