Dr. William Li, founder of the Angiogenesis Foundation, says that a common theme shared by cancers is faulty angiogenesis. Per this Article:
"Angiogenesis is the body's ability to grow new capillary blood vessels. Faulty angiogenesis occurs when there is insufficient, excessive or abnormal growth of blood vessels. Li compiled a comprehensive list of naturally occurring dietary sources of anti-angiogenic substances. The list includes green tea, strawberries, oranges, lemons, apples, cherries, red grapes, bok choy, kale, ginseng, maitake mushrooms, turmeric, artichokes, pumpkin, parsley, garlic, tomato, olive oil and dark chocolate.."
Another Study says "regular consumption of a chocolate rich in flavanols confers substantial photoprotection and can thus be effective at protecting human skin from harmful UV effects".
