    • Not essential nutrients, but may have health benefits.
    • Structural components of plants but not the exact same as the original plant matter.
    • Not absorbed by the body in the same way as the original plant substance.

    Essential Nutrients

    • Nutrients the body cannot produce in sufficient quantities.
    • Must be obtained through dietary intake.
    • Example: omega-3 fatty acids.

    Energy-Yielding Nutrients

    • Macronutrients that provide energy.
    • Broken down to release chemical energy from food.
    • Examples: proteins, carbohydrates, and fats.
    • Energy is measured in kilocalories (kcal).

    Types of Nutrients

    • Water: Composed of hydrogen and oxygen; an inorganic compound.
    • Minerals: Basic, inorganic nutrients not easily broken down.
    • Vitamins: Organic compounds (contain carbon).
    • Carbohydrates: Organic compounds.
    • Proteins: Organic compounds containing nitrogen.
    • Lipids (Fats): Organic compounds.

    Body Composition

    • Water makes up a significant portion of the human body.
