Sweet preference predicts mood altering effect of and impaired control over eating sweet foods.

The purpose of the present study was to examine association between hedonic response to sweet taste and a mood altering effect associated with eating sweet foods and impaired control over eating sweets. Participants (n=163, 39% males) rated a series of sucrose solutions for intensity of sweetness and palatability and completed a newly developed 12-item Sweet Taste Questionnaire (STQ). It was shown that STQ identifies two factors in the individual's attitude towards sweet foods: sensitivity to the mood altering effect of sweets and impaired control over eating sweet foods. Individuals preferring the taste of the strongest offered sucrose concentration reported a stronger mood altering effect associated with eating of sweet foods and were more likely to have an impaired control over eating sweets than the rest of the group. Women generally had higher scores on both factors compared to men. The results of the present study support the hypothesis that hedonic response to sweet taste is associated with elevated sensitivity to mood altering effects of sweet foods and impaired control over eating sweets.
