Final answer:
Carbohydrates, fats, and proteins are key macronutrients for our body. Carbs serve as an energy source, fats are used mainly as stored energy and organ protection, while proteins are needed for cell growth, repair, and maintenance.
Step-by-step explanation:
Carbohydrates, fats, and proteins are three essential macronutrients that our body requires in substantial amounts to function properly. Each serves a unique purpose in the body.
Carbohydrates are the body's primary source of energy. They are broken down into glucose which is used for energy in our bodies. Examples include sugars, starches, and fiber.
Fats are a concentrated source of energy. They provide essential fatty acids and are the main way the body stores energy. Fats also insulate your body and protect your organs.
Proteins are fundamental for cell growth, repair, and maintenance. Proteins are broken down into amino acids, which are often referred to as the 'building blocks' of life. A diet with adequate protein is crucial for maintaining muscle mass.
