Zheng Xinyi, a nutritionist at Taiwan Province Cancer Foundation, said that the difference between oolong tea and green tea and black tea lies in the degree of fermentation in the production process. Green tea belongs to unfermented tea, such as green tea, Longjing tea and Biluochun. Oolong tea belongs to semi-fermented tea, and its fermentation degree is about 15 ~ 70%, such as frozen top tea, Tieguanyin tea and Bai Hao oolong tea. Black tea belongs to fully fermented tea with fermentation degree of 100%, such as Hongyu black tea and Assam black tea.
Does oolong tea have the best degreasing effect? Tea polyphenols and catechins reduce fat absorption.
As for the online rumor that "drinking oolong tea has the best effect of eliminating oil." Nutritionist Zheng Xinyi pointed out that according to the literature, tea polyphenols and catechins can really reduce triglycerides and total cholesterol in the body, and can also * * * the activity of pancreatic lipolytic enzymes, reducing the absorption of sugar and fat in food by the intestine.
In animal experiments, it is found that oolong tea and green tea in the above three kinds of tea also have the functions of accelerating body heat production, promoting fat burning and reducing abdominal fat accumulation. Therefore, whether you drink oolong tea or green tea, it will help you lose weight. In addition, some oolong teas will add dietary fiber, which will make you feel full and reduce fat absorption.
Although drinking oolong tea can accelerate the metabolism of body fat and make it difficult to accumulate fat, we should also remind people that the key to success in losing weight lies in controlling calories, balancing diet, drinking proper amount of water, getting enough sleep and exercising regularly. If you just want to lose weight by drinking tea, but don't control calories and exercise, I'm afraid it will only expand the stomach capacity, which is not conducive to losing weight.
