A Fatty Liver And Green Tea Protection
The cost of obesity to an individual's health includes potential additional damage to their physiological systems, structures, and organs like the liver. Nonalcoholic fatty liver disease has increased with increasing obesity. A new study tested green tea extract (GTE) with obese mice and lean mice. After six weeks of green tea extract, the body weights of the obese mice were 23-25% lower and the body weights of the lean mice were 11-20% lower than control mice not fed green tea extract. Fat in the liver was reduced by green tea extract in a dose dependent manner. Green tea helped protect against liver injury probably by reducing serum alanine aminotransferase activity by 30-41% and reducing aspartate aminotransferase activity by 22-33%. Vitamin E, Vitamin C, and adiponectin-mediated fat metabolism were not significantly affected (Bruno RS, Journal of Nutrition, 2008). Researchers concluded that green tea extract protected the liver from obesity by limiting the accumulation of lipids in the liver. Green tea is known to block the absorption of fatty lipids in the intestine, thus increasing the direct elimination of fat before it is absorbed. These studies are considered preliminary. Additional research is needed to determine all the biochemical pathways involved in green tea's protection against a fatty liver from obesity.
