Mean (±SEM) state anxiety score (A,B), perceived energy levels score (C,D), and perceived emotion score (E,F), per food condition (square, milk chocolate snack; dot, dark chocolate snack; triangle, cheese and cracker snack) reported by participants in the high (A,C,E) and low (B,D,F) anxiety trait groups. The mean of the scores was generated from the data collected from the three test days (since no differences were observed over the days). A higher reported score is associated with lower experienced anxiety, a higher energy state and better emotional state.
