Blueberries come from a perennial flowering plant. These indigo coloured berries are not only a very popular fruit but have one of the highest antioxidant capacities among all fruits and vegetables. Antioxidants are essential to combat the free radicals that can damage our cells. Blueberries are an excellent source of vitamin K and manganese, also a good source of vitamin C, fibre and copper. Purchase local organic in season, when not in season purchase organic frozen blueberries.
