At least in mice, long-term consumption of a sugary and caffeinated soft drink in combination with a high-fat cheeseburger diet reduces the chemosensory surface of the fungiform taste papillae. This is the conclusion of a cooperative study conducted by the Faculty of Chemistry at the Austrian University of Vienna and the Faculty of Medicine at Slovakia's Comenius University. However, the extent to which a long-term consumption of a diet high in sugar and fat affects the human taste perception apparatus has not yet been clarified and requires further investigation according to Veronika Somoza and Barbara Lieder. Both are principal investigators at the Vienna Faculty of Chemistry and significantly contributed to the study. In addition, Veronika Somoza is the director of the LSB.
