Nutrients and Their Types

What are Nutrients?

Nutrients are substances that provide energy and support growth, maintenance, and repair of living organisms.

Types of Nutrients

There are two main categories of nutrients:

Macronutrients

• Provide energy and support growth
• Include:
  • Carbohydrates (e.g., sugars, starches, fiber)
  • Proteins (e.g., amino acids)
  • Fats (e.g., triglycerides)

Micronutrients

• Essential for various bodily functions
• Include:
  • Vitamins (e.g., A, C, D, E, K)
  • Minerals (e.g., calcium, iron, potassium, zinc)

Functions of Nutrients

Energy Production

• Carbohydrates, proteins, and fats provide energy for the body

Growth and Development

• Proteins and essential amino acids support growth and development

Regulation of Metabolic Processes

• Vitamins and minerals regulate various metabolic processes (e.g., energy production, nerve function)

Maintenance of Healthy Tissues

• Vitamins and minerals help maintain healthy tissues (e.g., skin, hair, eyes)

Importance of Nutrients

• Adequate nutrient intake is essential for maintaining optimal health and preventing deficiencies and diseases.
