Define the Prevention of diseases - Function of Vitamin E?

Because of its anti-oxidant function and its role in inhibiting cell proliferation of smooth muscles, vitamin E can be used for prevention treatment of diseases. Epidemiological studies suggest that dietary vitamin E influences the risk of cardiovascular disease. It has also been suggested that  vitamin E supplementation (200-400 mg/day) may be appropriate therapeutically  to moderate some aspects of degenerative diseases such as Parkinson disease,  reduce the severity of neurologic disorders such as tar dive dyskinesia (petentially  irreversible and involuntary movements), prevent periventricular haemorrhage in  pre-term babies, reduce tissue injury arising from ischaernia and reperfusion  during surgery, delay cataract development, and improve mobility in arthritis  sufferers.
