Population 2 consisted of 100 individuals with type 2 diabetes with dietary intakes assessed by using 2 sets of 3-d food records administered 2 wk apart. Dietary counseling was provided between food records 1 and 2. Dietary intakes between genotypes were compared by using analysis of covariance adjusted for potential confounders.\nRESULTS: In population 1, a significant Ile191Val × body mass index (BMI; in kg/m²) interaction was detected for the consumption of sugars, and the effect of genotype was significant only in individuals with a BMI ≥ 25 (n = 205). In comparison with individuals homozygous for the Ile allele, Val carriers consumed fewer sugars (122 ± 6 compared with 103 ± 6 g sugar/d, respectively; P = 0.01). Regression estimates that associated BMI with total sugar consumption by Ile/Ile and Val-carrier genotype intersected at a BMI of 23.5. In population 2, Val carriers also consumed less sugar than did individuals with the Ile/Ile genotype (99 ± 6 compared with 83 ± 6 g sugar/d, respectively; P = 0.04) on food record 2, and sugar was the only macronutrient that decreased significantly (-9 ± 4 g sugar/d, P = 0.02) in Val carriers who received dietary counseling.\nCONCLUSION: Our findings show that a genetic variation in TAS1R2 affects habitual consumption of sugars and may contribute to interindividual differences in changing behaviors in response to dietary counseling."}
