Recently, ANZ Food Standards Bureau issued notice 101-19 saying that it is considering banning the retail of pure and high concentration caffeine food, and has drafted a draft of food regulatory measures, which attracted the attention of netizens. Not long ago, caffeine was just on the hot search because it was detected in milk tea, and triggered a "milk tea panic" in some people. What is caffeine? Why does every appearance cause some people's panic? It has been reported that pure or high-purity form of caffeine may cause health damage to consumers. Recently, FSANZ announced that it has drafted a proposal to prohibit the sale of pure and high concentration caffeine food in Australia and New Zealand. Public information shows that caffeine is a plant alkaloid, which exists in many plants. It stimulates the central nervous system, temporarily dispels sleepiness and restores energy. Therefore, caffeinated coffee, tea, soft drinks and energy drinks are very popular. Experts said that when the body is tired, it will secrete a kind of adenosine substance. After this kind of substance acts on the body, it will "tell" you need to go to rest. However, after drinking caffeinated drinks, the caffeine with similar molecular structure to adenosine will rob the receptors of human body with adenosine, so that the body can not receive the signal of need to rest, which is the important reason for keeping a good mood. In addition, it has been found that caffeine can also increase dopamine in the brain, make the heart and liver work actively, increase adrenaline secretion, and keep people happy. According to scientific consensus, it's OK for healthy adults to take 400mg of caffeine every day, but the specific situation also depends on people's response to caffeine and the speed of metabolism and decomposition of the individual body.
With the help of caffeine, we can maintain a relatively high level of nerve excitement, alertness and attention, and improve work learning ability and motor performance. But when caffeine is overdone, it may cause anxiety, nervous tension and other negative effects. Due to the different tolerance of each person to caffeine, plus too much caffeine intake will lead to insomnia, headache, too much excitement will produce a lot of nerve stimulation, cause anxiety, even physiological diseases, patients with heart basic diseases are better not to drink. There is no need to fear caffeine in our daily life, but when it comes to "caffeine", many consumers still panic. As an example, many consumers are afraid of the caffeine contained in milk tea, and even say they will never drink milk tea again. But Yun inadvertently, a senior member of the American Food Technology Association and a science writer, said that the basic composition of milk tea is "milk + tea", and normal tea contains caffeine. This was the case from the day milk tea was invented. There are only two situations of milk tea without caffeine: one is "decaffeinated tea", which can be realized technically, but few people drink it in reality; the other is "fake milk tea" without tea ingredients, which should be investigated and dealt with by the regulatory authorities. Therefore, you don't need to worry about the possible health problems caused by caffeine as long as you take it properly.
