Green Tea Polyphenols, DNA Repair, and Prevention of Photocarcinogenesis

Naturally occurring plant polyphenols constitute a wide variety of phytochemicals which are distributed in plant foods, including fruits, vegetables, seeds, nuts, owers, and bark. Important dietary sources of polyphenols are grape seeds, grape skin, tea, apples, red wine, onions and cacao, and so on (Manach et al. 2004). These polyphenols possess benecial health effects of dietary sources. Among the well-known polyphenols, the polyphenols from tea and more specically from green tea are better known for their health benets in many organs as well as in general health. In this chapter, we particularly discuss and describe the health benets of green tea polyphenols (GTPs) with particular emphasis on protection against ultraviolet (UV) radiation-induced skin cancer through repair of damaged DNA.
