Flavonoids

Flavonoids, an extended class of chemically related compounds ubiquitously present in plant foods. In a range of experimental models, these compounds have demonstrated biological effects, which may partially explain the beneficial health effects of a diet high in vegetables and fruits.

Flavonoids are present in tea, apples, onions and red wine. High intakes were observed in Japan due to high consumption of tea, in Slavonia (Croatia) due to a high intake of onions and in Dalmatia (Croatia) because of a high intake of red wine.
