We need to eat carbohydrates every day because they are important for optimal physical and mental performance. But, not all carbs are created equal. While “good carb” isn’t defined in the dictionary, this carb is hard at work helping our brains and bodies perform their best, curbing cravings and fueling activity, whether we’re working out or just getting through the day. With potatoes you get the energy, potassium, and vitamin C you need to fuel you.
