As we know, free radicals are the damaging compounds which are created by the body’s metabolic processes. They also enter the body through unhealthy food, cigarette smoke, alcohol, pollution, etc. The free radicals attack body cells, which end up in many lethal diseases and ageing. With the regular use of green tea, we can effectively deal with the free radical damage. Studies across the world reveal how regular use of green tea helps reduce hypertension induced cognitive impairment, trims bad cholesterol, cuts dementia risk, strengthen bones, reduces the risk of a variety of cancers, avoids bad breath and the like.
