Liking and perceived saltiness of reduced and low sodium juice
following repeated exposure Subjects in the abrupt group had increased liking for all of the
reduced salt samples at the final taste test relative to the initial
taste test (p < 0.01 for all samples), though liking for the sample
with the highest sodium content (640 mg) was unchanged
(p = 0.59). Subjects in the gradual group had increased liking for
all samples at the final taste test (p < 0.01 for 136 mg and
304 mg; p = 0.05 for 472 mg and 640 mg) (Fig. 1). Subjects in the
gradual group found the highest sodium sample (640 mg) saltier
at the final taste test relative to the initial taste test (p = 0.04).
There were no changes in perceived saltiness intensity for any of
the samples between taste tests among subjects in the abrupt
group (Fig. 2).
Hedonic sensitivity to salt and motivation to reduce dietary salt intake
Though all levels of motivation and hedonic sensitivity were
included in the analyses, ratings from somewhat motivated sub-
jects and subjects with medium hedonic sensitivity almost always
fell between those from highly motivated and unmotivated sub-
jects and those from subjects with low and high hedonic sensitiv-
ity, respectively. For this reason, we have focused our presentation
of results on highly motivated versus unmotivated subjects and
subjects with low versus high hedonic sensitivity in each salt
reduction group.
