Step-by-step explanation:
The seven basic food components that provide nutrients to the human body are proteins, fats, carbohydrates, vitamins, minerals, water, and fiber. Nutrients are critical substances the body needs for energy, building materials, and control of body processes. There are six main classes of nutrients: carbohydrates, protein, fats, vitamins, minerals, and water, with fiber often considered the seventh due to its role in aiding digestion. While enzymes, sugar, and nucleic acids play roles in the body's overall function and health, they are not classified as one of the basic food components providing nutrients in the way that fiber does.
