A few days ago, a well-known vitamin functional beverage was deeply immersed in the use of additives. This news once again pushed the previously controversial functional drinks to the forefront. In fact, in the eyes of nutrition experts, functional drinks are not “souls” or “supplements”. Only when you drink on demand, you can achieve the corresponding functions. Excessive drinking may be harmful to your health.
Functional drinks must be served on demand
It seems to have become a routine for students to come to a bottle of energy drink before the test and before giving birth. White-collar workers seem to have become a consensus by “drinking energy and beauty for themselves” by drinking vitamin drinks every day. However, these habits and concepts related to functional drinks are not correct.
Wang Yumei, director of the Nutrition Department of the First Affiliated Hospital of Tsinghua University, said that for normal people with good health, there is no practical significance in drinking functional drinks in addition to quenching thirst without physical exertion and energy supplementation.
In fact, regarding functional beverages, there are clear explanations and definitions in relevant regulations. The definition of functional beverages in the Chinese Soft Drinks Classification Standard is to adjust the proportion of natural nutrients and content in beverages to suit the nutritional needs of certain special populations, including sports drinks, nutrient drinks and other special-purpose beverages. Big class.
Wang Yumei pointed out that each functional beverage is targeted at a specific group of people. Therefore, when selecting functional beverages, consumers need to carefully read the ingredients indicated on each beverage and select beverages according to their own characteristics. For example, after the exercise is consumed, some sports drinks can be consumed, and the minerals contained therein can quickly replenish the body’s body consumption due to exercise. If the body does not need it, such beverages are of course not required by the human body, and such beverages are not suitable for everyone. For example, children and high blood pressure patients should use such beverages with caution.
Excessive taurine affects heart health
Many functional drinks leave the impression that they can solve the problem. Experts point out that adding some ingredients to a functional drink can really help to relieve sleepiness and replenish energy, such as caffeine and taurine. A few days ago, the reporter visited some big supermarkets in Beijing and found that taurine and caffeine were added to many functional drinks such as vitamin drinks and sports drinks on the supermarket shelves.
Wang Yumei introduced that taurine is a nutritional enhancer, also known as α-aminoethanesulfonic acid, which was first isolated from bezoar and is a non-protein amino acid containing sulfur. Taurine does have many good effects, such as anti-fatigue, improving immunity, and promoting mental development in infants and young children. Caffeine is mainly used to excite nerves.
However, the intake of taurine and caffeine is not as good as possible. The reporter found that many functional beverages containing taurine did not indicate their specific content. It is understood that, in general, normal human taurine: 700 ~ 1000 mg, 1-2 times a day (up to 6 grams per day).
Previously, researchers at the Henry Ford Hospital in Detroit, USA, found that high levels of caffeine and taurine increased blood pressure and heart rate, affecting heart function. A study at the Australian Adelaide Hospital found that a brand of functional beverages can thicken blood and potentially increase the risk of heart disease and stroke. The Annals of Pharmacotherapy contains tests conducted by researchers at Wayne State University in the United States on functional beverages (mainly a brand of energy-based beverages): 15 healthy adults drink 2 functional drinks a day for 7 consecutive days. The results showed that functional drinks increased their blood pressure by an average of 10 mm Hg and heart rate increased by 5 times per minute. This means that for people with high blood pressure or arrhythmia, the drink may not be appropriate.
Functional beverage mix and match wine high risk
Many functional drinks are still the favorite of cocktail lovers. They use a variety of functional drinks to mix and match all kinds of wines to make delicious drinks. They are also the best sellers in many bars.
However, because functional drinks may contain caffeine, this practice can harm the health of the heart.
Li Shuyuan, executive director of the China Nutrition Association and director of the Clinical Nutrition Branch, pointed out that due to the excitatory effects of caffeine, many people mistakenly think that they are not drunk after drinking such beverages, so they drink too much. When the alcohol works, the body may not bear the weight. live.
Caffeine mixes alcohol and still hurts the heart. Because alcohol is quickly absorbed by the digestive system, and then enters the blood circulation system, affecting the function of the gastrointestinal, heart, liver, kidney, brain and endocrine organs, causing disturbances in the metabolism of the body, the most severely affected is the brain, which forms the height of the brain. inhibition. Drinking coffee can make the brain highly excited. If you drink alcohol and coffee at the same time, it will make the brain from extreme excitement into extreme inhibition, stimulate blood vessels to dilate, accelerate blood circulation, and greatly increase the cardiovascular burden.
The US Food and Drug Administration (FDA) has warned that it is neither safe nor legal to drink caffeine and alcohol, and that such drinks are removed.
