    Study Notes

    Flavonoids and Anthocyanins: Dietary Effects, Health Benefits, and Sources

    • Flavonoids are a diverse class of polyphenolic compounds found abundantly in plants. They are responsible for the vibrant colors of fruits, vegetables, and flowers.

    • Anthocyanins are a subclass of flavonoids, responsible for the red, purple, and blue pigments in many fruits and vegetables.

    Dietary Effects and Health Benefits

    • Flavonoids and anthocyanins have demonstrated various potential health benefits, largely due to their antioxidant properties.
    • Studies suggest that these compounds may contribute to reducing the risk of chronic diseases like cardiovascular disease and certain cancers, possibly by:
      • Neutralizing free radicals, preventing cellular damage, and inhibiting oxidative stress.
      • Reducing inflammation.
      • Improving blood vessel health by promoting nitric oxide production and lowering blood pressure.

    Sources of Flavonoids

    • Flavonoids are widely distributed in plant-based foods.
    • Common sources include:
      • Berries (strawberries, blueberries, raspberries)
      • Apples
      • Grapes
      • Citrus fruits (oranges, lemons)
      • Onions
      • Tea (green, black, white)
      • Dark chocolate
      • Red wine

    Antioxidant Properties

    • Flavonoids are potent antioxidants due to their ability to donate electrons to free radicals, stabilizing them and preventing further chain reactions that can cause cell damage.
    • The antioxidant capacity of flavonoids can vary significantly depending on their specific chemical structure.
    • Some flavonoids have higher antioxidant activity than others.

    Anthocyanin Structures

    • Anthocyanins are glycosylated anthocyanidins, which means sugars are attached to the basic anthocyanidin structure.
    • The sugar molecules attached to the anthocyanidin influence the anthocyanin's properties, including its color, stability, and bioavailability.
    • Different glycosylation patterns give rise to various anthocyanins with different hues and functionalities.
    • The glycosylation pattern significantly impacts the anthocyanin’s absorption in the gut.
    • The diverse anthocyanin structures lead to variation in their absorption and metabolic fate in the body influencing their overall activity.
    • Examples of common anthocyanidins include:
      • Cyanidin
      • Delphinidin
      • Malvidin
      • Pelargonidin
      • Peonidin
    • These anthocyanidins are further modified by sugar molecules (glycosylation) to form a vast array of anthocyanins.
    • The structural diversity of anthocyanins is a key factor in their varied physiological effects and biological activities.
