Trans fatty acid intake and emotion regulation.

ABSTRACT

We examined whether there is a relationship between trans fatty acid intakes and emotion regulation, mediated by positive or negative affect. Archival data on 1699 men and 3293 women were used to measure trans fatty acid intake at baseline, positive, and negative affects and emotion regulation at follow-up. Higher trans fatty acid intake related to subsequent difficulties with emotional awareness (p = 0.045), clarity (p = 0.012), and regulation strategies (p = 0.009). Affect mediated these relationships. Lower trans fatty acid intake associated with increased positive and decreased negative affects which, in turn, associated with improved emotion regulation. Trans fatty acid intakes may be associated with subsequent ability to regulate emotions.
