this is a true story that happened in Australia.

in May 2018, 14-year-old female student F, like other students in school, is working hard to prepare for the final exam.

one night, when F’s mother entered her room, the fruit tray in her hand fell to the ground — in front of her, was her daughter, who was constantly twitching on the ground.

“her upper and lower teeth creak, and her whole body twitches and vibrates violently!” After the event, F’s mother still couldn’t calm down when she described her daughter’s state that night.

she immediately sent her daughter to the doctor, and the doctor immediately rescued F. the nurse on the side kept asking her mother if there was a history of heart disease in her family and whether her daughter had cardiovascular disease…

fortunately, after comprehensive treatment and examination, the girl regained consciousness. The cause of the doctor’s note for F is: “a sudden increase in heart rate, uncontrolled body tremor.”

after waking up, her mother and the doctor inquired about her recent diet. After thinking about it, f said that I had drunk two cans of that drink the night before.

and

turns out that “that drink” is a refreshing functional drink that can be seen everywhere in supermarkets.

functional drinks are not to be able to drink

if you want to drink them. Xia Pengbin, the Clinical Nutrition Department of Zhongda Hospital, said that the functional drinks do have the effect of refreshing the mind for ordinary people, because it contains a lot of caffeine, taurine and other ingredients, but the large intake of these substances may pose a threat to people’s health. A large amount of caffeine intake may affect the visceral function, especially those who are sensitive to caffeine, often feel flustered, dizzy, even nauseous, resulting in heart discomfort, palpitations, arrhythmias and a series of adverse reactions, and even induce sudden death and other emergencies.

Therefore, it is suggested that people should not drink the functional drinks blindly. Some athletes and people who are prone to fatigue and other specific groups can drink some of these drinks appropriately. However, for children and adolescents who are in the development stage, if they are over supplemented with these ingredients, the burden of self-regulation will be increased, even more than that of the digestive system, kidney, liver and so on The tolerance of the nervous system.

therefore, in view of the high sugar and caffeine contained in energy drinks, which may have adverse effects on the body, most large supermarkets in the UK will ban the sale of energy drinks to young people under the age of 16. In fact,

, and

are not only functional drinks, but also many other “health” drinks in daily life. I hope you can have a correct understanding.

these “health” drinks are not necessarily beneficial to health, listed in the “blacklist”,

,

1. Fresh juice: it is better to eat fresh fruit

. The expert team of Wuhan food and Drug Administration said that drinking fresh fruit juice is not like eating fresh fruit directly. Fruits can lose a lot of essential dietary fiber in the process of fresh pressing, and dietary fiber is of great significance to prevent diabetes and cardiovascular diseases.

and

for children with new deciduous teeth, eating fruit rich in fiber and having certain hardness can enhance the chewing power of children, and promote the development of dental bed, jaw and facial bone.

2. Herbal tea drinks: sugar content is beyond your imagination.

herbal tea is also a popular drink in recent years. It is said that it has the effect of eliminating fire, because it contains Chinese medicine ingredients. Zhu Yi, an associate professor at the school of food science and nutrition engineering at China Agricultural University, said that the most important ingredient in many herbal teas is beverage, but there are few traditional Chinese medicines. If you pay attention to the ingredient list, you will find that water is the first, sugar is the second, and the content of traditional Chinese medicine is relatively low.

so generally speaking, herbal tea beverage is a kind of ordinary sugar beverage in essence. It’s better to make chrysanthemum tea at home.

, 3. Brain tonic drink: two walnuts

. When it comes to brain tonic drinks, many people’s first thought should be the “x walnuts” which were popular in the past few years, so we take this as an example. Although the beverage emphasizes the word “walnut”, according to the protein content of the beverage, the content of walnut is less than 2, only 1.87, and its main components are more water and white granulated sugar.

and

and related experts said that walnut brain tonic issue itself is controversial, and walnut beverage content is so small, not to mention the brain tonic effect. In addition, the State Food and drug administration has also indicated that China has never approved health food with functions such as brain tonifying and IQ improving.

4. Red wine: don’t expect it to protect blood vessels.

there are a lot of rumors that red wine can protect blood vessels, mainly because it contains resveratrol, which has anti-inflammatory, antioxidant and cardiovascular protection effects. However, it should be noted that these effects are only found in animal experiments, which are effective in vitro cell and animal experiments, and do not necessarily mean that they are effective on human body. In addition, the dosage is also a problem. The resveratrol content in red wine is very low, usually only 0.5-10 mg / L. if you want to soften blood vessels, normal people need to drink more than hundreds of bottles of red wine every day, which is impossible in real life.

and

on the contrary, a large amount of alcohol intake (8% – 15% alcohol content in red wine) is certainly harmful to people, which not only damages the cardiovascular system, but also induces cancer.

,

,

, ,

,

,

in a word, it is unnecessary to drink health.

and

there are many other better ways of life. It is better to drink boiled water to quench thirst. If it’s just because you like it, it’s better to understand the composition table first, especially some functional drinks, which are not suitable for the elderly, children and pregnant women. Drinking blindly may bring adverse effects on the body.
