A low sugar or no sugar peanut butter is reputed to be an excellent energy booster. It is not only rich in protein but contains energy-boosting minerals. Peanut butter has a strong nutty flavor with heart-healthy oils that makes it a good baking replacement for saturated fat staples like butter and shortening. Peanut butter can add an exciting pop to your baking or is tasty on its own as a spread on bread with applesauce on top or in your favorite green smoothies.
