A 2017 study of ~6,500 individuals with detailed eating records concluded that the rs838133(T) allele (in SNPedia and dbSNP orientation) increased the odds ratio (OR) of being in the top 33% of people for total intake of all types of sweet-tasting foods, with an OR of 1.18 per T-allele (CI: 1.06–1.32, p = 0.003). When sweet intake was divided into “candy” and “cake,” individuals carrying the T-allele had higher candy intake (OR 1.19, CI: 1.07–1.32, p = 0.0007), whereas intake of cake was the same regardless of rs838133 genotype.
