YES! Carbohydrates (or carbs) fuel your body and your brain. In fact, your brain prefers glucose, a type of carbohydrate, over other fuels. The source of the carbohydrates you eat is the more important question. Sticking to whole foods like fruits and veggies, whole grains (breads, crackers, and pastas), and dairy will give you the most nutrients per carb and give you enough energy to get through the day!
