Something will happen: According to Xinhua News Agency, a man in Britain died of a heart attack while working at night shift. The latest death report shows that his death may be related to drinking too much functional drink Red Bull every night. The British newspaper reported on the 24th that the dead man was named Alfredo Duran, from Bolivia. Since 2003, he has worked in a supermarket in Oxfordshire, England. In September 2006, Duran, then 40 years old, died of a heart attack while working at night shift. According to the survey, in order to refresh himself, Duran drinks a lot of red bull drinks when he works at night every day. On the night of his death, Duran drank no less than four cans of red bull drinks. Pathologist Ian Robert recently told the cause of death investigation team that Duran's heart was enlarged and his death may be related to excessive caffeine intake. "For people with this constitution, stimulating substances such as caffeine are at risk of causing heart problems, although this level of intake will not affect normal people." Robert said. It is reported that the caffeine content in a can of red bull drink is equivalent to that in a cup of coffee. The manufacturer of red bull drinks denies that red bull can do harm to the body, but recommends that you drink no more than two cans a day. A spokesman for the company told the newspaper that the clinical examination and "extensive" toxicological evaluation of Red Bull beverage showed that Red Bull was as safe as other adult beverages.
