Biological effects of hydroxytyrosol, a polyphenol from olive oil endowed with antioxidant activity.

Abstract: A number of epidemiological studies indicate that dietary factors may influence the development of some types of cancer and degenerative pathologies, including cardiovascular diseases and cataract. In this respect, it is well documented that daily consumption of fruits and vegetables is associated with a lowered risk of these diseases.1 Polyphenols are bioactive substances that are widely distributed in the vegetable kingdom2,3 and therefore are present in high concentrations in typical components of the Mediterranean diet, such as fruit, vegetables, red wine, and olive oil. The aim of this article is to overview the most recent data on the nutritional value of the phenolic fraction of virgin olive oil in the ongoing studies on its beneficial effects on human health.
