•Intake patterns of coffee and tea differ by BMI.•A preference for bitter white coffee is associated with PAV haplotype of TAS2R38.•Sweet snacks consumption is associated with drinking coffee or tea. The main aim of this study was to analyze coffee and tea intake patterns considering body weight status and polymorphism of genes involved in bitter taste sensitivity. A group of normal weight and overweight or obese subjects aged 20–40 (n = 411) was recruited in Poznań, Poland. Three-day dietary records were used to assess daily intakes. Single nucleotide polymorphisms (SNPs) were genotyped using TaqMan SNP probes (TAS2R38: rs713598, rs1726866, rs10246939) or the high-resolution melting method (CA6 rs2274333). 67.2% of the group drank coffee and 70.6% drank tea. Drinking only coffee was associated with higher body mass index (BMI) (OR = 4.81, p = 0.041). BMI ≥ 25 kg/m2 was associated with higher coffee intake (p = 0.010) and lower tea intake (p = 0.003). Higher taste-sensitivity of TAS2R38 gene was associated with a preference for bitter white coffee (OR = 1.74, p = 0.033). Over 50% of respondents ate sweet snacks while drinking coffee or tea. Consumption of sweet snacks was associated with drinking bitter black coffee (p = 0.044, OR 1.97) and sweet white coffee (p = 0.003, OR 2.92) and with BMI below 25 kg/m2 (p = 0.016, OR = 0.51). Coffee and tea intake differed by body weight status. PAV haplotype (TAS2R38) was associated with a preference for bitter white coffee. The majority of the study group drank coffee and tea with additives (sugar, milk etc.) and ate sweet snacks with them.
