Answer 1

Carbohydrates often receive negative attention as the dieter's enemy. Yet the American Dietetic Association argues that they should be your main source of energy, accounting for 45 to 65 percent of your total daily calories. That's because carbs are your body's quickest fuel source, ultimately yielding the simple sugar glucose. Glucose fuels metabolic reactions throughout your body and is the only form of energy that your brain can use.
