London: Chewing flavourless gum could hamper your memory, a new British study has revealed.According to researchers from Cardiff University in the UK, people who chewed gum had a harder time recalling lists of letters and numbers than those who avoided the habit.Researchers believe that the motion involved in chewing deter the brain’s ability to memorize serial lists.Just like tapping your finger or foot may distract you from accomplishing the same task, continual movements like chewing on a piece of gum can also interfere with your short-term memory.The study challenges the prevailing notion that chewing gum, at least when it is flavoured, is a performance enhancer that can boost brainpower.According to Chicago Tribune, the study provides further proof that human beings are bad at multitasking.Some previous studies have argued that gum improves concentration by triggering an increase in blood flow through the brain, said lead author Michail Kozlov, of Cardiff University.But his team found that an oral activity such as gum chewing could interfere with the process that is normally used to remember verbal content, the Daily Mail reported.
