Drink your prevention: beverages with cancer preventive phytochemicals.

Specific alimentary habits, including oriental and Mediterranean diets characterized by high consumption of vegetables, fruits, cereals and, for the Mediterranean diet, olive oil, are associated with a reduction of risk of cardiovascular diseases, type 2 diabetes, neurodegenerative diseases and some cancers. Numerous beverages contain diverse natural compounds, termed phytochemicals, that have been reported to exert anti-tumor, anti-angiogenic and anti-oxidant properties. Here we review the chemopreventive and angiopreventive properties of selected phytochemicals found in common beverages: epigallocatechin (green tea), triterpenoids (citrus juices), resveratrol (red wine), xanthohumol (beer), procyanidin (chocolate) and caffeine (coffee), focusing on their molecular mechanisms, providing "ready to drink" prevention approaches.
