Whole wheat flour is a type of flour made from grinding the entire wheat kernel, which includes the bran, germ, and endosperm. This process retains more nutrients compared to refined flours, making it a healthier option for baking and cooking. Whole wheat flour is rich in fiber, vitamins, and minerals, contributing to better digestion and overall health. Commonly used in bread, pancakes, and muffins, whole wheat flour adds a nutty flavor and denser texture to baked goods. It can often be substituted for all-purpose flour in recipes, though adjustments in liquid may be needed due to its higher absorbency.
