TAS2R38 and CA6 genetic polymorphisms, frequency of bitter food intake, and blood biomarkers among elderly woman

摘要

Objective: Taste sensitivity is one of the most important biological determinants of food choice. Three SNP5 of the TAS2R38 gene (rs713598, rs1726866, and rs10246939) give rise to two common haplotypes: PAV and AVI. These haplotypes, as well as an SNP within the CA6 gene (rs2274333) that encodes carbonic anhydrase VI (CA6), correlate with bitterness perception. The extent of consumption of bitter food may influence some health outcomes. The aim of this study is thus to investigate the impact of the TAS2R38 and CA6 genetic polymorphisms on the choice of bitter food, BMI, blood lipoprotein, and glucose concentrations as well as systemic inflammation in elderly women.
