Vegetables are an important part of a balanced diet.
The six classes of essential nutrients required in the human diet are:
- Carbohydrates1
- Lipids (primarily fats and oils)1
- Proteins1
- Vitamins1
- Minerals1
- Water1
These nutrients are categorized based on their roles in the body. Carbohydrates, lipids, and proteins are known as macronutrients; they provide the raw materials for tissue maintenance and the energy necessary for physiological activities. Vitamins and minerals are micronutrients; while they do not provide energy themselves, they are essential for facilitating various metabolic processes. Finally, water is the most critical nutrient, serving as the medium for metabolic reactions, transport, and temperature regulation.12
Although these nutrients are discussed in separate categories, they function in collaboration within the body to sustain life.1
