Antioxidant News and Research

RSS

Antioxidants are substances that protect cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging. Antioxidants include beta-carotene, lycopene, vitamins A, C, and E, and other natural and manufactured substances.

Green tea protects livers

A new study investigating the effects of the major flavonoid component of green tea on hepatic steatosis (fatty liver) found that it significantly protected livers that suffered ischemia/reperfusion (I/R) injury in mice. I/R injury, which is caused by decreased blood flow, can lead to complications after liver transplantation.
