Washington: Our taste preferences may change with age, a new study on mice suggests.Japanese researchers found that taste preference changes in different life stages of rats.Ageing elicits changes in taste preferences and such changes appear to be independent of taste nerve activity, researchers said.In humans and animals ageing decreases dietary and energy requirements and it is generally believed that reduced consumption is related to alterations in taste preference.However, the mechanisms underlying an age-induced shift in taste preference remain unclear. Thus, the researchers investigated differences in fluid intake and taste nerve responses across different age groups of rats.The researchers initially measured the intake of sweet, salty, umami, sour or bitter taste solutions in 5 age groups; juvenile, young-adult, adult, middle-aged and old-aged male rats.
