  • While much is known on how the maternal diet affects offspring fitness, less is known on the role of taste in guiding and promoting food intake during this crucial period. Women have intense food cravings and exhibit altered taste preferences during pregnancy, however the mechanistic details underlying these changes are presently unclear. We performed longitudinal brief-access taste testing in female mice before, during, and after pregnancy, along with quantitative PCR on taste buds and morphological analysis of taste tissues from pregnant and non-pregnant mice. Sucrose licking response decreased progressively during pregnancy compared to that prior to mating, with partial recovery in the post-partum period. No change in taste morphology was evident between pregnant and non-pregnant mice, however a notable decrease in T1R3 sweet taste receptor mRNA expression was recorded in pregnant dams. We conclude that altered taste preferences during pregnancy likely result from changes in the expression profile of taste buds in the mother, which may promote a less healthy diet while expecting.
