A cup of milk tea under the belly, the 23-year-old girl's face is full of wind balls! Is there an allergy to milk tea?

Many young people like to drink milk tea, and Xiao Zhang, a 23-year-old young girl, is one of them. But she didn't expect that she was almost knocked down by a cup of milk tea.

Xiao Zhang fell in love with milk tea when he was in college, and drank it for almost six or seven years, and had never been allergic before. Until February this year, she and her colleagues once went shopping, during which they bought a cup of milk tea and some snacks. That afternoon, her face began to itch, and colleagues noticed that she had a lot of red wheals on her face, which made her realize that she was allergic. Since she did not have severe symptoms, she did not go to the hospital, and the wheals persisted for two or three days and then relieved themselves.

At that time, I did not think that it was a milk tea allergy, and a few days later, my colleague invited her to drink a cup of milk tea, and her face was again a wheezy, which realized that it may be the problem of milk tea.

Since then, she has been more careful to observe whether drinking different brands and different kinds of milk tea will be allergic. It turned out that she was only allergic to some kinds of milk tea, and found that some milk tea varieties were not allergic before drinking, and later tried some new products to be allergic.

Subsequently, Xiao Zhang came to the Allergy Department of the Second Affiliated Hospital of Zhejiang University School of Medicine, and the doctor considered that it was urticaria caused by milk tea allergy according to her medical history and symptom characteristics, but the allergen group screening was normal.

I didn't find out anything when I went to the hospital, but the question in her heart was still not eliminated, was she allergic to milk tea?

The answer is yes. According to the characteristics of Xiao Zhang's medical history, Dr. Yao I, a skin thadophore attack occurred after drinking milk tea many times, considering that it was indeed an allergic reaction caused by milk tea, which was specifically manifested as the onset of urticaria.

Is it allergic to what ingredients in milk tea?

Xiao Zhang himself also observed that the same is milk tea, not every drink is allergic. As we all know, milk tea is a complex mixture, the most important ingredient of which is milk + tea. The main components of milk are: water, fat, protein, carbohydrates, minerals, vitamins, etc. Milk and dairy products are one of the main allergenic foods.

Casein, α-lactoalbumin and β-lactoglobulin in milk protein are the main allergen components of milk. The main ingredients of tea are: tea polyphenols, amino acids, alkaloids (caffeine, theobromine, theophylline), tea polysaccharides, tea pigments, water, as well as some vitamins and inorganic minerals, aromatic substances, etc. Patients with tea allergies are very rare, and there are also clinical reports of patients who are allergic to caffeine and theophylline drugs.

However, most milk teas on the market, in addition to milk and tea, also contain sugar, cream, condensed milk, vegetable fat powder (hydrogenated vegetable oil), coffee extract, acidity regulator, emulsifier, thickener, flavor and other additives. In addition, with the continuous innovation of the types of milk tea, in order to cater to the different tastes and needs of consumers, milk tea also adds a variety of "small ingredients", such as pearls, coconut fruits, red beans, pudding, roasted fairy grass, taro puree, aloe vera, red rice jelly, crispy notes, taro balls, sago, silk tofu, etc., these additives and "small ingredients" ingredients can also be allergens.

Because Xiao Zhang is only allergic to some specific varieties of milk tea, she is most likely allergic to some additive in milk tea.

What should I do if I have an allergy to milk tea?

For milk tea allergies, no matter which ingredients in it are allergic, diet avoidance (not drinking) is the best and most thorough way. Of course, if you are only allergic to a few specific milk teas, and you prefer to drink milk tea, you can choose to drink milk tea that is not allergic. If it is for all people who are allergic to milk tea, they can only give up the love of drinking milk tea. Food allergies, mild may only develop urticaria, heavy may cause shock life-threatening, can not be ignored.

In addition, because of the problem of many additives in milk tea, it has been listed as "junk food". Long-term large-scale drinking may lead to obesity, sleep quality decline, accelerate skin aging, increase the risk of cardiovascular disease and other hazards, so it is not recommended that you drink a lot of long-term.
