Reduces the risk of cancer – Researchers have determined that Green tea contains Epigallocatechin Gallate (EGCG). This not only prevents the growth of cancer cells but also kills the cancerous cells – without impairing the functions of any normal cells. This EGCG helps reduce the risk of a range of cancers namely esophageal & lung cancers. Also impacts the occurrence of breast and prostate cancer. Incidentally, EGCG is found to be more potent than a chemical called resveratrol which is present in red wine. This chemical is the key to the “French Paradox”: Despite heavy consumption of cheese & cheese based products, the French are found to have relatively lesser levels of cholesterol compared to their American counterparts. Such is the significance of EGCG which is found in high levels in green tea as against other types of teas. The reason is, while preparing green tea the leaves have to be heated under steam while in the other types such as black tea the process involved is different. In such processes, the EGCG turns into some other compounds.

Lowers the ldl cholesterol levels – Basically, our human body contains two types of cholesterols – Low Density Lipoprotein (LDL) & High Density Lipoprotein (HDL). Since LDL particles block the arteries and veins and hence lead to high risk diseases, they are often called the bad cholesterol particles, and the HDL particles are generally termed as good particles. Green tea helps in lowering such LDL cholesterol particles in human body.

Lowers chances of cognitive degeneration – Recently concluded study in the east states that green tea lowers cognitive degeneration among people who drank a cup of green tea every day as against those who had some other beverage or those who consumed less than the stated amount.

This effect could be explained by the effect of effect of EGCG, which seeps through the blood-brain membrane.
