A few days ago, a well-known vitamin functional beverage was caught in the storm of illegal use of additives. This news once again pushed this pre-controversial functional beverage to the cusp. In fact, in the eyes of nutrition experts, functional beverages are not “spiritual†and they are not “supplements.†Only drinking on demand can achieve corresponding functions. Excessive drinking may be harmful to health.
Functional drinks must be consumed on demand
It seems to have become a common practice for students to have a bottle of energy drink before the exam and during the delivery of pregnant women. White-collar workers seem to have become a consensus by drinking vitamin drinks every day to "maintain their vitality and beauty." However, these habits and concepts related to functional beverages are actually not correct.
Wang Yumei, director of the Department of Nutrition at the First Affiliated Hospital of Tsinghua University, said that for healthy, healthy people, there is no practical significance for drinking functional beverages except for physical exertion and energy supplements.
In fact, there are clear explanations and definitions in the relevant regulations regarding functional beverages. The definition of "functional soft drinks" in the "China Soft Drinks Classification Standard" is to adjust the proportion of natural nutrients and their content in beverages to suit the nutritional needs of certain special groups, including sports drinks, nutrient drinks and other special-purpose beverages. Big class.
Wang Yumei pointed out that each type of 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 based on their own characteristics. If you exercise after a large consumption, you can drink some sports drinks, which contain minerals can quickly supplement the human body due to exercise and consumption of substances. If the body does not need such beverages, of course, these types of beverages are not needed 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.
Taurine Excess Affects Heart Health
Many functional beverages leave people with the impression that they are able to solve the problem. Experts pointed out that adding some ingredients in functional drinks can indeed help to alleviate fatigue and supplement physical strength, such as caffeine and taurine. A few days ago, the reporter visited some big supermarkets in the capital and found that taurine and caffeine were added to many functional beverages such as vitamin drinks and sports drinks on supermarket shelves.
According to Wang Yumei, taurine is a nutritional enhancer, also known as α-aminoethane sulfonic acid, which was originally isolated from bezoar and is a sulfur-containing non-protein amino acid. Taurine does have many good effects, such as anti-fatigue, boosting immunity, and promoting intellectual development of infants and young children. Caffeine is mainly used to make nerves excited.
However, the more intake of taurine and caffeine, the better. The reporter found that many taurine-containing functional beverages did not specify its 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, United States, discovered that high levels of caffeine and taurine increase blood pressure and heart rate and affect heart function. A study at Adelaide Hospital in Australia found that a certain brand of functional beverages can make blood thicker and may increase the risk of heart disease and stroke. The Thenalsf Pharmacotherapy contains tests conducted by researchers at Wayne State University in the United States on functional beverages (mainly referring to a certain brand of energy-based beverages): 15 healthy adults drink 2 functional beverages per day for 7 consecutive days. They found that functional beverages increased their blood pressure by an average of 10 mm Hg, and their heart rate increased by 5 times per minute. This means that for someone with hypertension or arrhythmia, the beverage may not be suitable.
Functional drinks mix high alcohol risk
A lot of functional drinks are also favorite of cocktail lovers. They use various types of functional beverages to mix and match various types of drinks to make delicious, good-looking drinks, and are also popular in many bars.
However, because functional drinks may contain caffeine, this practice may 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 excitement of caffeine, many people mistakenly believe that they are not very drunk after drinking such drinks, and therefore drink too much. When alcohol works, the body may not tolerate it. live.
It is still the heart that caffeine mixes alcohol. Because alcohol is rapidly absorbed by the digestive system, it then enters the blood circulatory system and affects the functions of the gastrointestinal, heart, liver, kidney, brain and endocrine organs, causing disorders in the body's metabolism, the most serious of which is the brain that forms the brain. inhibition. Drinking coffee will make the brain highly excited. If drinking alcohol and coffee at the same time, it will cause the brain to turn from extreme excitement to extreme inhibition, stimulate blood vessels to dilate, accelerate blood circulation, and greatly increase the burden on the cardiovascular system.
The U.S. Food and Drug Administration (FDA) has warned that caffeine and alcohol-drinking beverages are neither safe nor legal, and they will be removed from the shelf.
