Seasonal dynamics of taste threshold to sweet stimuli of men in the North were studied. The object of the study were volunteers - male students (n = 60). The mean age was 22,1 ± 1,0 years. The seasonal differences in the magnitude of taste threshold dynamics to sweet stimulus were revealed. Middle dynamics of taste threshold for sweets during the winter (0,47 ± 0,01)% was 1,78 times lower (p
