    • Nutrient: A chemical component necessary for energy provision, tissue repair, and regulation of life processes.

    Nutrients

    • Functions of Nutrients:
      • Provide energy for biochemical reactions.
      • Build and repair body tissues.
      • Regulate various bodily functions to maintain homeostasis.
    • Types of Nutrients:
      • "Go Foods": Provide energy.
      • "Grow Foods": Build the body.
      • "Glow Foods": Regulate body processes.

    Nutritional Status

    • Defined as the condition of the body from utilizing essential nutrients.
    • Classification:
      • Good Nutrition: Adequate supply and utilization of nutrients.
      • Malnutrition: Results from a lack of essential nutrients (deficiency) or excessive nutrient supply (over-nutrition).
    • Forms of Malnutrition:
      • Undernutrition: Inadequate intake leading to issues like wasting, stunting, and underweight.
      • Overnutrition: Imbalance between energy intake and expenditure, often resulting in overweight or obesity.

    • Essential micronutrients include iodine, vitamin A, and iron, with deficiencies posing a significant health threat, particularly in low-income countries.

    Imbalance Nutrition

    • Describes a pathological state due to disproportional nutrient intake, affecting metabolic health.

    Dietary Standards

    • Set minimum nutrient requirements tailored by age, sex, weight, and health conditions, known as Recommended Energy Intake (REI) or Nutrient Intake (RNI).

    Food Quality

    • Defined as the degree of a food product's excellence and its fitness for human consumption.
    • Quality factors include identity, net quantity, sensory attributes, stability, wholesomeness, and proper packaging and labeling.
