Explain the different types of nutrients and their functions.

Nutrients are essential substances in food that provide energy, support growth, and maintain body functions. They are broadly classified into six main types.

Carbohydrates are the primary source of energy for the body. They provide quick energy and are found in foods like rice, bread, and fruits.

Proteins are responsible for growth and repair of body tissues. They are found in foods such as pulses, eggs, meat, and dairy products.

Fats provide a concentrated source of energy and help in the absorption of fat-soluble vitamins. Sources include oils, butter, nuts, and seeds.

Vitamins are required in small amounts but are essential for regulating body processes and preventing diseases. For example, vitamin C helps in immunity, while vitamin D supports bone health.

Minerals are important for various body functions such as bone formation, oxygen transport, and nerve function. Examples include calcium, iron, and potassium.

Water is vital for all life processes, including digestion, transportation of nutrients, and temperature regulation.

Each nutrient has a specific function, and a balanced intake of all nutrients is necessary for maintaining good health.
