We all know that eating plenty of vegetables and fruits, and drinking green tea can also prevent cancer, heart attack and stroke in particular.
Green tea and apples are rich in compounds called ‘polyphenols’, and these have a protective effect by blocking a signaling molecule called ‘vascular endothelial growth factor’. VEGF is the main driver behind blood-vessel formation (angiogenesis), a process responsible for cancerous growth as well as the buildup of plaque in arterial walls, which can lead to heart attacks and strokes.
And this is not just theory; it’s a process that researches at the Norwich Institute of Food Research were able to observe in blood samples.
Polyphenols also activate another enzyme that helps promote nitric oxide in the blood,, which helps to relax blood vessels and prevent arterial damage.
