The chemical compounds used by the body to function and maintain health are called **nutrients**. Nutrients are substances that provide nourishment essential for growth, maintenance of life, and overall health.
There are six main types of nutrients that the body needs:
1. **Carbohydrates**: Provide energy for the body. Sources include grains, fruits, and vegetables.
2. **Proteins**: Essential for growth, repair, and maintenance of body tissues. Sources include meat, dairy, and legumes.
3. **Fats**: Important for energy storage, insulation, and cell function. Sources include oils, nuts, and avocados.
4. **Vitamins**: Essential for various bodily functions. They can be obtained from fruits, vegetables, and supplements.
5. **Minerals**: Needed for strong bones, healthy teeth, and other bodily functions. Sources include dairy, nuts, and leafy greens.
6. **Water**: Vital for hydration, digestion, and overall body function.
In contrast, the other options listed—preservatives, toxins, and additives—are not substances that the body uses to function and maintain health. Instead, they are typically found in processed foods and can have negative effects on health if consumed in excess.
