On the streets in summer, there is always a long line in front of the hot business milk tea shop, forming a 'unique landscape' on the roadside. A cup of instant milk tea with more than ten yuan is sought after by adults and children. But recently, experts on Weibo said that drinking milk tea can't give birth to children. What's the matter? Why does drinking milk tea affect fertility?
But many milk tea shops don't use fresh milk to make milk tea. Some waiters will take powder from the jar and mix it with water to make a cup of milk tea.
Where is the milk? Where is the tea?
Recently, the Shanghai Municipal Commission of consumer protection issued a notice on "milk tea comparative test". The tested samples basically covered the best-selling products of the mainstream milk tea brands in the market. In a test of protein, it was found that the protein content was significantly lower. In a test of trans fatty acids, it was obviously too high.
Yin Xuan, nutritionist of the Nutrition Department of Hangzhou first people's Hospital, said that the imbalance between the two indicators indicates that the merchants are likely to use milk essence and other substitutes in the raw materials of milk.
Yin Xuan said that milk is rich in high-quality protein, B vitamins, vitamin A, vitamin D and other vitamins, as well as calcium, phosphorus, iron, zinc and other minerals. Milk and dairy products are the best source of calcium, not only rich in content, but also high in absorption rate.
But the milk essence (i.e. vegetable fat powder) is made up artificially. It is extracted from vegetable oil by chemical hydrogenation. Its main components are sugar, saturated fat and trans fatty acid. Its protein content is low and fat content is very high. Trans fatty acids produced during hydrogenation are not only harmful to our health, but also harmful.
'trans fatty acids can increase serum total cholesterol, low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol, and reduce high-density lipoprotein cholesterol. "According to Yin Xuan, studies have shown that trans fatty acids have a certain negative impact on the development of children's nervous system; large intake of trans fatty acids in young people will reduce fertility, and men will reduce hormone secretion, inhibit sperm activity, and have a negative impact on sperm activity; memory will be reduced in old age, and the probability of Alzheimer's disease will increase.
The 'Pearl' in milk tea should be made of tapioca starch, but the pure tapioca starch can't make the 'Pearl' elastic, but after adding the synthetic polymer material, the Pearl becomes very chewy, and such material can't be absorbed by human body.
There is no milk and tea in milk tea, instead of a mixture of a variety of additives, it will only be harmful to the human body.
How can I drink healthy milk tea? It's very simple, just do it yourself.
1. Select the better black tea, put it in the boiling pot and boil for two or three minutes, filter out the tea, and put the tea into the cup;
2. After the pure milk is heated and boiled, add the prepared black tea, and the proportion can be adjusted according to the concentration of black tea according to personal taste;
3. When the milk tea is slightly cool, it can be seasoned with honey at about 70 ℃. A cup of light and mellow milk tea is ready! If you think it's monotonous, you can also change your pattern. Add a variety of diced fruits, lemon slices or nuts such as hazelnut and walnut to the milk tea, and it tastes different.
