The two main types of carbohydrates are simple carbohydrates and complex carbohydrates. Simple carbohydrates, often referred to as sugars, consist of one or two sugar molecules and can be found in foods like fruits, honey, and table sugar. Complex carbohydrates, composed of longer chains of sugar molecules, include starches and fiber, commonly found in whole grains, legumes, and vegetables. While simple carbohydrates provide quick energy, complex carbohydrates release energy more slowly and are generally more nutritious, offering additional benefits such as vitamins, minerals, and dietary fiber.
