For many young people today, milk tea is an indispensable drink. If you don’t drink it for a day, you will feel uncomfortable.However, in addition to causing physical attacks and weight gain, the calories in milk tea also cause certain magical damage due to the large amount of sugar contained. Recently, scientists from Tsinghua University and Central University of Finance and Economics surveyed more than 5,000 college students in Beijing and found thatMilk tea can be addictive. 16.3% of students meet the criteria for addiction, which is more serious for girls and younger people. It is also related to depression and anxiety.

In addition, studies have found that excessive intake of sugar can cause a corresponding decrease in a protein called BDNF (brain-derived neurotrophic factor) in the brains of mice.

This protein is widely distributed in the central nervous system and has nerve regeneration and repair functions.BDNF and its receptors are also considered to play a very important role in improving depression and antidepressant drug treatment. Therefore, their reduction can easily cause negative emotions such as anxiety, tension, and depression.

Like nicotine, alcohol, heroin, etc., sugar can also promote the secretion of dopamine. We all know that dopamine is the source of happiness for the human body. Only when the brain secretes enough dopamine can frustrated humans feel that the world is worthwhile.

But dopamine also has tolerance. The happiness that once was brought by a piece of sugar will increase with long-term sugar intake, and more sugar will be needed to obtain the same amount of dopamine secretion. Sugar addiction is therefore similar to other addictions in that it is always accompanied by increasing intake of the addictive substance.

Scientists say that given the growing popularity of milk tea, this issue needs attention and some rules should be formulated, such as limiting milk tea advertising.
