Taste changes during pregnancy.

J E Brown, R B Toma

    The American Journal of Clinical Nutrition
    |March 1, 1986
    PubMed
    Summary
    This summary is machine-generated.

    Pregnancy alters taste perception, making it harder for expectant mothers to detect salt concentration changes. Pregnant women also prefer saltier solutions, suggesting a biological drive to increase salt intake during gestation.

    Area of Science:

    • Physiology
    • Human Sensation
    • Pregnancy Studies

    Background:

    • Taste perception can change during physiological states.
    • Pregnancy involves significant hormonal and physiological shifts.
    • Dietary intake is crucial for maternal and fetal health.

    Purpose of the Study:

    • To investigate alterations in taste sensitivity and preference during pregnancy.
    • To determine if pregnant women exhibit changes in salt and sucrose perception.
    • To explore potential physiological mechanisms influencing taste during gestation.

    Main Methods:

    • Assessing pregnant and nonpregnant women's ability to discriminate salt and sucrose solution concentrations.
    • Evaluating taste solution preferences in both groups.

    Related Experiment Videos

  • Statistical analysis to compare sensory discrimination and preference between groups.

    • Main Results:

    • Pregnant women showed significantly reduced ability to identify salt concentration differences compared to nonpregnant women (p < 0.005).
    • Pregnant women demonstrated a significant preference for stronger salt solutions (p = 0.004).
    • No significant differences were noted for sucrose solutions (data not shown).

    Conclusions:

    • Pregnancy is associated with diminished taste acuity for salt concentration.
    • A physiological mechanism may promote increased salt intake during pregnancy.
    • These taste changes could play a role in maternal physiological adaptations.
