New Delhi, April 15 (ANI): Scientists have found evidence supporting the health benefiting facts about certain foods like green tea and apples. Researchers have shown that polyphenols in green tea and apples block a signalling molecule called VEGF, which in the body can trigger atherosclerosis and is a target for some anti-cancer drugs. In the body, VEGF is a main driver of blood vessel formation in these cell types via a process called angiogenesis. Angiogenesis is crucial in cancer progression, as well as in the development of plaque rupture, which can cause heart attacks and stroke. Researchers said that if this effect happened in the body as well, it would provide very strong evidence for a mechanism that links dietary polyphenols and beneficial health effects.
