Area of Science:

  • Dietary science
  • Nutritional biochemistry

Context:

  • Flavonoids are abundant phenolic compounds in the human diet, found in fruits, vegetables, wine, and beer.
  • Over 5000 distinct flavonoids exist, with an average daily intake of approximately 23 mg, quercetin being the most prevalent.

Purpose:

  • To review the biological effects and health implications of dietary flavonoids.
  • To highlight the antioxidant and potential therapeutic properties of flavonoids.

Summary:

  • Initially disregarded for health benefits, flavonoids are now recognized for significant biological activities, primarily their antioxidant and free radical-scavenging capabilities.
  • While high doses may exhibit pro-oxidant effects, research predominantly indicates anti-inflammatory, antiviral, and anti-allergic properties.
  • Flavonoids are associated with a protective role in cardiovascular diseases, cancer, and other pathologies.
