Try­ing to quit the sweet stuff ? Ac­cord­ing to a study, your morn­ing cup of joy could be mak­ing it more dif­fi­cult for you, with re­searchers find­ing that caf­feine could tem­po­rar­ily af­fect your taste buds. It is known that caf­feine has a pow­er­ful ef­fect on adeno­sine re­cep­tors, which pro­motes re­lax­ation and sleepi­ness. It sup­presses these re­cep­tors and makes us feel more awake, which is why cof­fee so ap­peal­ing and widely con­sumed. How­ever these re­cep­tors also has another ef­fect — de­creas­ing the abil­ity of our taste buds to taste sweet­ness. Re­cent stud­ies have shown that adeno­sine re­cep­tors are present in sweet sen­si­tive taste cells of mice the new re­search, car­ried out by Cor­nell University, set out to look whether the caf­feine can also have an ef­fect on the taste buds of hu­mans. For this, the team re­cruited 107 par­tic­i­pants and ran­domly split them into 2 groups. One group of par­tic­i­pants were asked to drink cof­fee with 200 mil­ligrams of caf­feine added to it. The other group drank de­caf­feinated cof­fee. Both groups had sugar in their drinks. The team found that par­tic­i­pants, who drank caf­feinated cof­fee, rated it as less sweet than those who drank the de­caf­feinated one. “When you drink caf­feinated cof­fee, it will change how you per­ceive taste. If you eat food di­rectly after drink­ing a caf­feinated cof­fee or other caf­feinated drinks, you will per­ceive food dif­fer­ently," ex­plained se­nior au­thor Robin Dando. In ad­di­tion, par­tic­i­pants were also asked to rate their level of alert­ness and guess how much caf­feine had been in their cof­fee. Par­tic­i­pants re­ported the same in­crease in alert­ness after drink­ing ei­ther the caf­feinated or de­caf­feinated sam­ples, and failed to pre­dict if they had con­sumed the de­caf­feinated or the caf­feinated ver­sion. How­ever de­spite feel­ing more alert, there was no sig­nif­i­cant im­prove­ment in re­ac­tion times. “We think there might be con­di­tion­ing ef­fect to the sim­ple ac­tion of drink­ing cof­fee. So panelists felt alert even if the caf­feine was not there,” said Dando.
