Sweetness drives consumption of added sugars, so understanding how individuals differ is important for developing strategies to lower sugar intake. However, methods assess hedonic response sweetness vary, making results across studies difficult integrate. We compared measure optimal sucrose concentration in 21 healthy adults (1) using paired-comparison preference tracking vs. ratings liking, (2) with participants the laboratory at home, and (3) aqueous solutions vanilla milk. Tests were replicated on separate days test-retest reliability. Test-retest reliability was similar between home testing, but tended be better milk tracking. Optimal virtually identical slightly when estimated via tracking, about 50% individual correlated strongly Methods, test Locations, Stimuli.
