  1. Which fatty acid is classified as omega-3 and is found primarily in fatty fish?

    Answer: Eicosapentaenoic acid (EPA)

    EPA is a long-chain omega-3 fatty acid found in fatty fish like salmon and mackerel, and is important for reducing inflammation.

  2. What is the primary function of the mineral chromium in the body?

    Answer: Enhancing insulin sensitivity

    Chromium potentiates insulin action, helping regulate blood glucose by improving insulin sensitivity in cells.

  3. The glycemic load (GL) of a food differs from glycemic index (GI) in that GL also accounts for:

    Answer: The serving size and carbohydrate amount consumed

    Glycemic load multiplies the GI by the grams of carbohydrate in a serving and divides by 100, reflecting real-world blood sugar impact.

  4. Which vitamin is synthesized in the skin upon exposure to ultraviolet B (UVB) radiation?

    Answer: Vitamin D

    UVB radiation converts 7-dehydrocholesterol in the skin to previtamin D3, which is then converted to active vitamin D.

  5. In IIN's Health Coach Training, 'bio-individuality' means:

    Answer: One person's food can be another person's poison, so dietary needs are individual

    Bio-individuality is the IIN concept that each person has unique dietary needs and what works for one individual may not work for another.

  6. Which digestive enzyme is responsible for breaking down proteins in the stomach?

    Answer: Pepsin

    Pepsin is the primary proteolytic enzyme in the stomach, activated from pepsinogen by stomach acid to cleave peptide bonds.

  7. What does the term 'phytochemicals' refer to in nutrition science?

    Answer: Bioactive compounds in plants with potential health benefits

    Phytochemicals are naturally occurring bioactive compounds in plants — such as polyphenols, flavonoids, and carotenoids — linked to disease prevention.
