Questions and Answers

Which of these options accurately describes the difference between essential chemicals and phytochemicals?

  • Essential chemicals are nutrients that the body cannot produce, while phytochemicals are non-nutrient compounds found in plants that may have health benefits. (correct)
  • Essential chemicals are absorbed by the body in the same way as the original substance, while phytochemicals are not fully absorbed.

Study Notes

Nutrients

  • Chemicals found in food.
  • Provide various substances to the body, including energy, protein, and fats, etc
  • Can influence health conditions, tissue growth, and repair.

Phytochemicals

  • Naturally occurring compounds in plants.
  • 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.

Macronutrients vs. Micronutrients

  • Macronutrients: Provide energy (kilocalories).
    • Carbohydrates
    • Proteins
    • Fats
  • Micronutrients: Do not provide energy.
    • Vitamins
    • Minerals
