Bitter, Sweet, Salty, Sour and Umami Taste Perception Decreases with Age: Sex-Specific Analysis, Modulation by Genetic Variants and Taste-Preference Associations in 18 to 80 Year-Old Subjects.

In the whole population ( Table 3 ) we found a highly significant association between age (as continuous in years) and a lower taste perception for all tastes and for their sum (B = −0.070 (0.029) points/year age; p = 2.4 × 10 −9 ) even in the multivariate model (model 3) adjusted for sex, BMI, diabetes, smoking and medications.
