description Flavonoids Overview

Flavonoids are naturally occurring plant compounds belonging to a large family of polyphenols. They’re notable for their potent antioxidant properties, helping protect cells from damage caused by free radicals. Found abundantly in foods like berries, tea, and dark chocolate, flavonoids support overall health. This makes them particularly relevant for individuals seeking to promote cellular wellbeing and potentially mitigate inflammation.

help Flavonoids FAQ

What are the most common dietary sources of flavonoids?

Flavonoids are abundant in many plant-based foods, particularly berries, apples, citrus fruits, onions, and dark chocolate. Tea, especially green and black varieties, along with red wine, are also highly significant sources of these polyphenols.

What are the main subclasses of flavonoids found in food?

Scientists broadly categorize dietary flavonoids into six major subclasses. These include flavonols (like quercetin), flavones, flavanones, flavan-3-ols (like catechins in tea), anthocyanins, and isoflavones (found heavily in soy).

How do flavonoids act as antioxidants in the human body?

Flavonoids neutralize free radicals by directly scavenging reactive oxygen species (ROS) before they can damage cellular DNA and lipids. They also help chelate transition metals like iron and copper, preventing these metals from catalyzing further oxidative reactions.

What is the difference between flavonoids and flavanols?

The terms are often confused, but flavonoids are the broad overarching family of plant polyphenols, while flavanols (specifically flavan-3-ols) are just one specific subclass within that family. Flavanols are the specific compounds found in high concentrations in cocoa and green tea leaves.
