The main source of carbohydrates is plant-based foods. Carbohydrates are one of the three macronutrients the body requires, providing energy through sugars and starches. Foods rich in carbohydrates include grains (like rice and wheat), fruits, vegetables, legumes, and dairy products. Whole grains and fiber-rich foods, such as fruits and vegetables, are particularly beneficial as they provide sustainable energy and aid in digestion. While simple carbohydrates, found in sugary foods, can provide quick energy, complex carbohydrates from whole, unprocessed foods offer a steady source of fuel for the body and are crucial for a balanced diet.
