Study Notes
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.
