Nutrition info on blueberries:Often labeled a "superfood," the blueberry is bursting with nutrients, many of which are classified as antioxidants and phytochemicals.Much of the power of blueberries lies in their colors. The deep-blue hue comes from anthocyanin, a phytochemical whose abilities may help protect the body from heart disease and Type 2 diabetes, offering cancer-fighting benefits, promote gut health and reduce inflammation. Research also suggests regularly eating blueberries may improve memory and delay age-related cognitive decline.A one-cup serving of blueberries contains 25% of the recommended daily value for vitamin C and 4 grams of dietary fiber, but only 80 calories. Plus, blueberries are juicy fruits, which means they contain mostly water. That high water content makes them great for weight loss or maintenance because they fill you up quickly without a lot of calories.
