Whether fresh, frozen, pureed, or dried, fruit is a great complement to oats. The juices provide just enough sweetness, without having to resort to artificial additives. Try a spoonful of blueberries, which are packed with antioxidants, or stir in some all-fruit jam for a thicker consistency. Dried cranberries and apricots are also delicious, especially when paired with some crushed walnuts, almonds, or pecans. The nuts pack health benefits, too: a daily dose of walnuts could help lower your LDL cholesterol, according to a 2010 study.
