    Study Notes

    Nutrition Overview

    • Nutrition is the science of food, nutrients, and their effects on health.
    • It encompasses the processes by which organisms utilize materials for growth, maintenance, and energy.
    • Effective nutrition education contributes to nutritional well-being throughout life.

    Definition of Food and Nutrients

    • Food refers to any organic or inorganic substance that nourishes the body, aiding in tissue building, energy supply, and bodily regulation.
    • Nutrients are essential chemical components enabling the body to generate energy, build tissues, and regulate functions.

    Types of Nutrients

    • Three general functions:
      • Provide Energy: Supports biochemical processes.
      • Build and Repair Tissues: Necessary for organs and structures.
      • Regulate Body Processes: Maintains balance and homeostasis.
    • Nutrients categorized by function:
      • Go Food: Provides energy.
      • Grow Food: Builds body tissues.
      • Glow Food: Regulates bodily functions.

    Nutritional Status

    • Nutritional status (nutriture) reflects a body's condition based on nutrient utilization.
    • Classifications include optimal nutrition, malnutrition, and nutrient inefficiencies.
    • Malnutrition entails deficiencies, excesses, or imbalances in nutrient intake.

    Forms of Malnutrition

    • Undernutrition: Insufficient nutrient intake leading to:
      • Wasting: Low weight-for-height.
      • Stunting: Low height-for-age.
      • Underweight: Low weight-for-age.
    • Overnutrition: Excessive nutrient intake leading to overweight and obesity.
    • Specific Nutrient Deficiency: Lack of essential vitamins or minerals.

    Overnutrition and Health Risks

    • Overweight defined by a Body Mass Index (BMI) of 25 or more; obesity at 30 or more.
    • Diet-related noncommunicable diseases (NCDs) arise from unhealthy diets, including cardiovascular diseases and diabetes.
    • Deficiencies in vitamins and minerals hinder enzyme and hormone production.
    • Critical deficiencies include iodine, vitamin A, and iron, affecting health globally.

    Imbalance Nutrition

    • Results from excess or insufficient intake of essential nutrients.
    • Imbalance states may occur without absolute nutrient deficiencies.

    Dietary Standards and Requirements

    • Dietary standards provide minimum nutrient requirements for good health.
    • Recommended Energy Intake (REI) and Nutrient Intake (RNI) are recognized guidelines for maintaining health.

    Food Quality Considerations

    • Food quality pertains to the degree of excellence in products, fitness for consumption, and consumer satisfaction.
    • Criteria include identity, stability, sensory attributes, wholesomeness, and proper packaging.

    Factors Influencing Food Choices

    • Environmental and individual factors heavily impact food selection.
      • Macro-level: Larger societal influences.
      • Individual level: Personal preferences and needs.
