Pu-erh tea water extracts could potentially enhance liver health and reduce oxidative stress in rats on a high-fat diet.
Experimental Study Fatty Liver Disease Pu-Erh Tea
In this study, fifty SD rats were split into five distinct groups and subjected to a high-fat diet. Their body weights were noted daily. Researches measured the serum levels of malondialdehyde (MDA), glucose, catalysts such as alanine aminotransferase and aspartate aminotransferase, nitric oxide synthase, and pyruvate kinase. Besides, hepatic glycogen levels were assessed, along with the activity of liver enzymes like total superoxide dismutase, catalase, and glutathione peroxidase. These measurements were consistently undertaken for a duration of 12 weeks.
The findings showcased a decrease in the body weight and fat index of rats after the administration of Pu-erh tea extract. The reduction in body weight and fat index was accompanied by a decrease in malondialdehyde and nitric oxide synthase levels. Interestingly, there was also a noticeable increase in the activities of hepatic total superoxide dismutase, catalase, and glutathione peroxidase. These findings suggest that the Pu-erh extract might reduce the oxidant stress state, inhabit lipid peroxidation, and protect liver health in rats. Simultaneously, the extracts seemed to boost the production of liver glycogen, enhance the activity of pyruvate kinase, and decrease glucose levels, thereby possibly safeguarding the liver from diseases linked to Type II Diabetes.
