Tastes change with age, at least in rats, new research suggests.
Younger rats prefer more sugar and umami flavor in foods and showed a stronger aversion to bitter foods compared with elderly rats, according to a study presented today (July 30) at the annual meeting of the Society for the Study of Ingestive Behavior.
"To our knowledge, this is the first report demonstrating a reduced aversion to bitter taste in aged rats," study co-author Chizuko Inui-Yamamoto, a researcher at Osaka University in Japan, said in a statement.
