Oolong tea and green tea are produced by the same kind of tea tree. The biggest difference is whether it has been fermented or not. Because the catechins in tea will combine with each other with the increase of fermentation temperature, the color of tea will become darker, but the astringency of tea will also decrease. The component formed by catechin combination is the polyphenol of oolong tea. Antioxidant polyphenols and catechins can affect the activation of various enzymes in our body. About half of catechins in tea will be converted into polyphenols in oolong tea. Therefore, under the dual effects of catechins and oolong tea polyphenols, oolong tea shows various functions that green tea does not have.
Oolong tea contains a lot of tea polyphenols, which can improve the function of lipolytic enzyme and reduce the cholesterol content in blood, and has the functions of lowering blood pressure, antioxidation, anti-aging and cancer prevention. A recent study published in the Journal of Obesity pointed out that people who regularly drink oolong tea have lower body mass index and fat content than those who drink less. Moreover, women lose weight more effectively than men. This is because compared with black tea and green tea, oolong tea can not only stimulate the activity of lipolytic enzymes in the pancreas, reduce the absorption of sugar and fatty foods, but also accelerate the increase of body heat production, promote fat burning, and especially reduce the accumulation of abdominal fat.
