Original title: Health and Wellness Functional drinks are "worse" than carbonated drinks
A study published in the journal American Heart Association suggests that functional drinks are more harmful to health than carbonated beverages, and even just one drink can cause "life-threatening" changes in blood pressure and heartbeat.
Travis Air Force Base Medical Center in the United States randomly divided 18 volunteers into two groups. One group drank 32 ounces (907 grams) of functional beverages available on the market, containing 320 milligrams of caffeine, 108 grams of sugar, taurine, ginseng, etc.; After 6 days, the two groups exchanged drinks. The researchers measured the volunteers' blood pressure 1, 2, 4, 6 and 24 hours before and after drinking, using an electrostartogram to observe their heartbeat.
results showed that the QT interstital period of volunteers who drank functional drinks was 10 milliseconds higher than that of the reference group leader. QT interstated period refers to the time period from the beginning of the QRS wave to the end of the T wave, which is the total time of the agitation of the heart. The extension of QT interstitia was directly related to the occurrence of narcissological arrhythmic, the risk of sudden coronary heart disease death, and mortality in normal populations. Time's website quoted researchers as saying on the 26th that the extension is significant, some of the drugs that can cause the QT period to be extended by 6 milliseconds will be marked with warning signs.
also found that both groups of volunteers had elevated blood pressure after drinking, but both were within the normal range. However, blood pressure returned to normal after 6 hours of drinking carbonated beverages, but remained high after 6 hours of drinking functional drinks. In addition to caffeine, the researchers believe there are other ingredients in functional drinks that alter blood pressure.
researchers say there is growing evidence that functional drinks have a different effect on the heart than pure caffeinated beverages, and that "consumers should be aware that drinking functional drinks is different from drinking coffee or carbonated beverages."
, however, the researchers acknowledge that the study has a small sample size and needs further study. (Huang Min) (Xinhua News Agency Micro Features)
