    • Critical for optimal growth, development, maintaining function, sound mental health, withstanding aging, and resisting environmental toxins.
    • 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)
      • Control of body processes foods: Regulate body functions (e.g., proteins, minerals, vitamins, water)
    • Food groups are also classified based on consumption patterns:

      • The Food Guide Pyramid (USDA, 1992) is a visual guide for recommended food intake.

    Nutrients

    • Foods contain various chemical compounds for nourishment:
      • Macronutrients: Required in large quantities (water, carbohydrates, fats, proteins)
      • Micronutrients: Vitamins and minerals (required in smaller amounts)

    Diet Purpose

    • The primary goal of a diet is to provide energy, nutrients, and other components needed for growth and maintaining body processes.
