Consuming large amounts of fruit and vegetables reduces risk of developing chronic conditions.

A study by Norwich BioScience Institutes has revealed that people who consume the largest amounts of have a reduced risk of developing , such as and .

The researchers hypothesize that contain high amounts of compounds called polyphenols, which provide protective health benefits as they contain high levels of anti-oxidant activity.

The researchers determined that low concentrations of the polyphenols epigallocatechin gallate (EGCG) from green tea and procyanidin from apples stopped a crucial signalling function of VEGF. VEGF is a main driver of blood vessel formation in these cell types via a process called angiogenesis. Angiogenesis is crucial in progression, as well as in the development of atherosclerotic plaques and plaque rupture which can cause heart attacks and stroke.

of VEGF signalling by dietary polyphenols has previously been implicated in other studies, but this study provides the first evidence that polyphenols can directly interact with VEGF to block its signals, at the levels you would see in the blood stream after eating polyphenol rich foods.

“If this effect happens in the body as well, it provides very strong evidence for a mechanism that links dietary polyphenols and beneficial health effects,” said Kroon, Leader at IFR.
