The researchers from University of California, Los Angeles have recently demonstrated the black tea contains a chemical, known as polyphenols can contribute to the major change in energy metabolism of liver by recasting the gut metabolites. The research has been published in ‘European Journal of Nutrition’.
The research study shown that both green and black tea can change the intestinal-bacteria ratio in animals. It is ratio of decreased obesity and percentage of bacteria associated with it, while bacteria get increased when associated with the lean body mass.
Previously, it has been considered by the scientists that the polyphenols in green tea are the most effective and beneficial for health than that of the black tea. However, the chemicals of green tea are soaked up by blood and tissues.
Black tea is usually served in the Chinese restaurants and to make an ice tea. It gets fermented that is a process of allowing it to be changed chemically and to increase its caffeine content ordinarily. It has a very strong distinct flavor with the concentration of the polyphenols which majorly helps to block the fats and prevents them from being absorbed by intestines. But, adding milk to the black tea may restrain its ability of blocking fats.
An adjunct professor from the UCLA Center’s Human Nutrition department at the David Geffen School of Medicine from the UCLA, and lead author of the study, Susanne Henning stated that, “It was known that green tea polyphenols are more effective and offer more health benefits than black tea polyphenols since green tea chemicals are absorbed into the blood and tissue. Our new findings suggest that black tea, through a specific mechanism through the gut microbiome, may also contribute to good health and weight loss in humans.”
