Flavonoids are active compounds, meaning that they interact with other chemicals in the environment. They are generally low in toxicity compared to other plant compounds, and when ingested by animals seem to provide various biological protections for the animals.
Many flavonoids act as powerful antioxidants, protecting against cellular damage. Flavonoids have also been shown to have anti-inflammatory and anti-cancer effects.
Pharmaceutical and food manufacturers have become interested in flavonoids for their medicinal properties, especially for their potential as treatments or preventative applications against cancers and heart disease.
Research about the beneficial effects of vegetables, fruits, tea, red wine and even beer have been attributed to the flavonoids in those foods rather than to any nutrients or vitamins contained in them. Several of these have been shown to provide protection against prostate and other cancers.
