In recent years, with the continuous disclosure of clinical medicine at home and abroad, the association between sugar intake and various chronic diseases has been repeatedly confirmed by experts and scholars. Recently, Gu Zhongyi, a master of public health from Tsinghua University and director of Beijing dietitian Association, released "drinking sugary drinks is better than drinking sugary drinks? No!" The article expresses its views on hot topics. Gu Zhongyi said that sugary drinks have a great impact on body organs. Taking a large amount of sugar for a long time will not only cause obesity, but also cause a series of chronic diseases and bring a number of injuries to the body. In this paper, Gu Zhongyi lists the harm of sugar in two time dimensions: short-term and long-term. When the short-term sugar intake of the human body exceeds the standard, it will bring a great burden to the metabolic system, aggravate the body's inflammatory reaction, and increase the risk of acne from the perspective of skin performance. Once the long-term sugar intake exceeds the health standard, the cognitive function of the brain will also be damaged, including the risk of chronic non communicable diseases such as heart disease and tumor will be greatly increased. In fact, this is not the first time Gu Zhongyi called on the public to reduce sugar intake. As early as 10 years ago, he released the sugar content table of common sugary drinks on the market, quantifying the sugar content in the form of square sugar, reminding the public to pay attention to sugary drinks as the "hardest hit area" of sugar intake. The article also posted an experiment of boiling sugary drinks. Compared with sugary drinks, sugary drinks obviously precipitate a large amount of syrup after cooking. Gu Zhongyi said that it must be difficult for ordinary people to eat the same amount of sugar normally, but putting these sugars into the beverage will "deceive" the public perception to a certain extent. One of the hazards of sugary drinks is that they will make people unconsciously consume too much sugar and increase the burden on the body. (outlook new era)
