Effects of long-term dietary supplement of tea polyphenols on lipid peroxide levels in rats

摘要

We examined the effects of tea polyphenols (TP) on the body weight gain and contents of lipids and lipid peroxides in rat plasma, kidney and liver.

Daily food intake of animals in two TP groups was almost the same as the control grou
