Factors Associated with Dietary Habits and Mood States Affecting Taste Sensitivity in Japanese College Women
Journal of Nutritional Science and Vitaminology
We conducted a cross-sectional survey to evaluate the factors associated with dietary habits and mood states affecting taste sensitivity in 127 Japanese college women with a mean age of 19.2 y. Differential thresholds for the four basic tastes on the tongue were determined by the fi lter paper disc method, while dietary intake was assessed using a food frequency questionnaire. Psychological mood states were evaluated by the Profi le of Mood State (POMS) questionnaire. Differential thresholds
... ntial thresholds for saltiness and bitterness in alcohol drinkers were higher than those in alcohol non drinkers, whereas differential thresholds for the other tastes did not differ signifi cantly between any of the stratifi ed groups. Canonical correlation analysis revealed that among the fi ve POMS mood states, POMS fatigue scores showed relatively stronger association with combined variables of taste thresholds. Logistic regression analysis revealed signifi cant involvement of zinc and iron intake, and that POMS fatigue and anger scores affected the differential threshold for sourness. Specifi c mood and dietary factors were shown to be associated with sensitivity to sourness and bitterness. Among the fi ve POMS mood states, high POMS fatigue scores and low POMS anger scores appeared to be associated with decreased taste sensitivity.
