- Nutrition science explores food, nutrients, their interactions, and impact on health and disease.
- It encompasses ingestion, digestion, absorption, transport, utilization, and disposal of nutrients, along with growth, maintenance, and repair processes in living organisms.
What is Food?
- Food provides:
- Energy for movement, heat production, etc.
- Materials for growth, repair, regeneration, and reproduction.
- Substances that regulate growth and repair processes.
Food Groups
-
Foods are categorized based on their functions:
- Energy-releasing foods: Provide energy (e.g., carbohydrates)
- Growth and repair foods: Build and repair body tissues (e.g., fats)
