5. Harm of milk tea to human body

1. Easy to get fat

Trans fatty acids are not easily digested by the human body, and easily accumulate in the abdomen, leading to obesity.

Drinking too much milk tea has many disadvantages to the human body. Milk tea is high in sugar, oil and calories. Most of the creamers added in milk tea are coconut oil. Coconut oil contains a lot of saturated fatty acids, which will accelerate the production of cholesterol in the body, and blood lipids will also rise rapidly, forming arteriosclerosis. Drinking a lot for a long time is prone to chronic diseases such as hypertension and diabetes.

Statistics show that drinking a lot of milk tea for more than three months in a row will increase blood lipids and cholesterol. Milk tea is only a combination of oil and sugar, because creamer is not finished milk, and there is a lot of sugar in milk tea, which contains almost no calcium, which is very harmful to the body. It is best not to drink milk tea every day, but to drink one or two cups at most a week to relieve your craving.

Aggravate hypertension

Caffeine is often combined with other simple painkillers because of its analgesic effect. However, if you take a lot of caffeine for a long time, if you already have high blood pressure, using a lot of caffeine will only make your situation worse. Because caffeine alone can raise blood pressure, if combined with emotional tension, it will have a dangerous multiplier effect. Therefore, people at risk of hypertension should especially avoid drinking caffeinated drinks when working pressure is high. Some people who have been drinking coffee for many years think that they are immune to caffeine, but this is not the case. A study shows that after drinking a cup of coffee, the blood pressure can rise for as long as 12 hours.

Trans fatty acids in milk tea will increase the viscosity and cohesion of human blood and easily lead to thrombosis, especially for the elderly with fragile blood vessel walls.

3. Induced osteoporosis

Caffeine itself has a very good diuretic effect. If you drink a lot of coffee for a long time, it will easily lead to bone loss, which will adversely affect the preservation of bone mass and may increase the threat of osteoporosis in women. However, the premise is that people who don't get enough calcium in food on weekdays, or people who don't exercise regularly, plus postmenopausal women, lose calcium due to insufficient estrogen. These conditions, combined with a large amount of caffeine, may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still do it without choking.

When you are nervous, it makes things worse.

Caffeine helps to improve alertness, sensitivity, memory and attention. But if you drink more coffee than you are used to, you will have the same dose of stimulants, which will cause tension. For people with anxiety tendency, caffeine can aggravate the symptoms of sweating, palpitation and tinnitus.

5. Vulnerable to infertility

The researchers found that women who drink 1 cup of coffee every day are more likely to suffer from infertility than women who don't drink coffee. Experts investigated 104 women who have the habit of drinking coffee, and about 50 of them are not easy to get pregnant. Some fertility experts believe that this is a small-scale study and cannot finally confirm the special role of coffee in fertility. However, the researchers stressed that if the cause of infertility cannot be explained medically, it should be considered that infertility is related to caffeine.

However, trans fatty acids in milk tea will reduce the secretion of androgen, have a negative impact on sperm activity and interrupt the reaction process of sperm in the body.

6. This is harmful to the fetus

During pregnancy or lactation, eating too much food containing trans fatty acids will affect the health of the fetus. Studies have found that fetuses or babies can passively ingest trans fatty acids through placenta or milk, and they are more likely to suffer from essential fatty acid deficiency than adults, which affects their growth and development.

7. Increase the risk of myocardial infarction

Doctors from the School of Public Health of Boston University conducted a four-year study on 858 women aged 45-69 who suffered from myocardial infarction for the first time and 858 women who had never suffered from myocardial infarction. The results show that drinking five or more cups of coffee a day can increase the risk of myocardial infarction in women by 70%, and the risk increases with the increase of coffee consumption.
