Carbohydrates are one of the three main macronutrients, along with proteins and fats, that provide energy to the body. They are found in a wide variety of foods, including fruits, vegetables, grains, and dairy products. Carbohydrates are classified into three main types: sugars, starches, and fiber. Sugars are simple carbohydrates found in fruits, vegetables, and dairy products, as well as in processed foods like candy and soda. Starches are complex carbohydrates found in foods like potatoes, rice, bread, and pasta. Fiber, also a complex carbohydrate, is found in plant-based foods like fruits, vegetables, whole grains, and legumes, and it aids in digestion. Carbohydrates are broken down into glucose, which is used by the body's cells for energy, especially for the brain and muscles during physical activity. A balanced intake of carbohydrates is important for overall health, supporting functions like energy production, digestion, and nutrient absorption.
