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.
