Many people suffer from insomnia after drinking it, a beverage with higher caffeine content than coffee. Caffeine | milk tea | coffee

In recent years, milk tea has become increasingly popular, and various internet famous milk teas seem to have become a source of happiness for more and more young people.

However, what many people don't know is that although milk tea is delicious, its caffeine content may be even higher than coffee, and drinking it may lead to insomnia.

How much caffeine does milk tea contain?

How much caffeine is there in a cup of milk tea? Someone may have seen this statement online:

A cup of milk tea contains caffeine equivalent to 7 cans of Red Bull;

A cup of milk tea has a caffeine content equal to 4 cups of coffee;

If you drink the cup of milk tea with the most caffeine, it's equivalent to drinking 4 cups of coffee or 8 cans of Red Bull;

……

First of all, the conclusion is that there is basically no problem with the above statement. The caffeine content in milk tea is indeed higher than that in coffee.

In 2017, the Shanghai Consumer Association conducted a spot check on milk tea and found that 51 varieties of milk tea from 27 milk tea shops contained a large amount of caffeine. Among all the samples, the average caffeine content in each cup is 270mg, with the highest being 480mg, which is basically equivalent to 4 cups of coffee or 8 cans of Red Bull. Keep in mind that a cup of American coffee contains only 108mg of caffeine; The caffeine content in a can of Red Bull beverage is only 50mg.

In 2019, the Consumer Committee of Guangming District in Shenzhen and the Shenzhen Food and Drug Safety Volunteer Service also tested 10 brands of pearl milk tea on the market. The results showed that all milk teas were found to contain caffeine, with an average content of 258mg/kg. Among them, the highest caffeine content is 522 milligrams per kilogram, which is equivalent to the total amount of caffeine in 7 cans of Red Bull.

Why is there caffeine in milk tea? This is because milk tea is made from "milk+tea", which contains caffeine.

The caffeine content in each gram of tea is generally around 20 milligrams, with some reaching up to 40 milligrams. When brewing tea, caffeine easily dissolves from the tea leaves into the water. It is worth noting that many milk teas on the market are made directly from concentrated tea powder, so the caffeine content is usually higher.

According to the results of the "Dietary Caffeine Intake Level and Risk Assessment for Chinese Residents", in China, the highest contribution rate of caffeine intake to adult consumers is tea, tea drinks, milk tea, and coffee; The highest contribution rates of caffeine intake among minors are milk tea, tea drinks, tea leaves, and chocolate.

That is to say, whether adults or children, when drinking milk tea, they should pay attention to the intake of caffeine and never assume that there is no caffeine inside.

Why do some people have a cup of milk tea

Will you wake up until dawn?

Many people say that drinking a cup of milk tea can lead to insomnia, poor sleep, and even waking up until dawn.

This is because caffeine has a stimulating effect on the central nervous system, and many people feel excited and unable to sleep after drinking it. Some people who are sensitive to caffeine may even be unable to sleep all night with a cup of milk tea.

However, the refreshing and stimulating effects of caffeine vary greatly among different individuals.

Because there are some genes in our body, such as CYP1A2, PDSS2, etc., that control the metabolism of caffeine. People with more active genes metabolize caffeine at a faster rate, and the caffeine they consume is quickly cleared out of the body. Therefore, drinking a few cups of milk tea does not affect sleep at all, and even if they drink milk tea, they may feel sleepy or sleepy.

But some people's coffee metabolism genes are relatively weak, and even a little caffeine needs to be metabolized for a long time. Even the coffee I drank in the morning still bounces in my mind at night, and I wake up with a cup of milk tea until dawn.

Is caffeine in milk tea safe?

What everyone is most concerned about is whether the caffeine in milk tea is safe and whether it can harm the human body.

From current research, it appears that moderate intake of caffeine is safe for normal individuals. Health agencies in countries such as the US FDA, EU EFSA, and Canada's Department of Health all believe that for healthy adults, consuming no more than 400 milligrams of caffeine per day is safe.

According to the results of the "Dietary Caffeine Intake Level and Risk Assessment for Chinese Residents", it is safe for adults to drink a maximum of 1524g of liquid milk tea per day and not consume other caffeinated foods. So, for a normal person, having a glass every day is completely fine.

Special reminder, teenagers and pregnant women are more sensitive to caffeine and are generally not encouraged to consume it. So, if you are a teenager, pregnant or breastfeeding, try not to drink it.

In addition, some people may be sensitive to caffeine and may experience symptoms such as insomnia, tremors, palpitations, and insomnia after drinking it. It is best not to drink it for now.

Can you rest assured to drink milk tea?

A cup of milk tea usually has no problem with caffeine, so friends who enjoy drinking milk tea can rest assured.

However, in addition to milk tea, many foods/drinks in daily life also contain caffeine, such as cola, tea, coffee, certain energy drinks, and chocolate. If you drink these drinks and eat chocolate, remember to drink less milk tea.

Moreover, everyone's tolerance for caffeine varies. Some people drink several cups of milk tea and coffee without any problems, while others feel uncomfortable after just a few sips.

So, it is recommended that everyone follow their own feelings. If you experience insomnia, anxiety, palpitations, tremors, stomach discomfort, increased heart rate, headaches, nausea, and restlessness after drinking milk tea, it may indicate that your caffeine tolerance has been exceeded and appropriate adjustments should be made - drink less.

In addition, the biggest health problem with milk tea is that it contains too much sugar and fat. Many good milk teas contain a lot of cream, and fat is definitely essential. The fat content in a cup of milk tea can usually reach 40-70 grams, while the sugar content in a cup of pearl milk tea ranges from 30-60 grams.

Everyone must pay attention to controlling the amount of milk tea they drink, otherwise they will only get fatter
