Berries like blueberries, cranberries, raspberries, blackberries, cherries, and strawberries are the top immune-boosting fruits.
These fruits contain phytochemicals (natural plant chemicals) that give them their vibrant colors, called anthocyanins. Berries are flooded with antioxidants, are an excellent source of vitamins and minerals, and are also high in fiber. They provide all this nutrition and are low in natural sugars to boot! They suppress the growth of several cancers and colds, reduce high blood pressure, and prevent strokes, arthritis, and osteoporosis.
