Event Abstract Back to Event Acute stress decreases food related reward activation in the brain during food choice Margriet S. Westerterp-Plantenga1, 2* 1 Maastricht University, Department of Human Biology, Nutrim, Netherlands 2 TIFood and Nutrition, Netherlands Human eating behavior may be influenced non-homeostatically by the rewarding value of foods, i.e. ‘liking’ (pleasure/palatability) and ‘wanting’ (incentive motivation). Stress appeared to diminish the rewarding value of food, i.e. ‘liking’ and ‘wanting’, leading to eating in the absence of hunger in the visceral overweight subjects. Postprandial energy intake was relatively higher during stress vs rest, resulting from more choice for crispiness and fullness of taste(p<.05). Then brain activation was reduced in reward-areas: Amygdala, hippocampus and cingulate cortex (AUC=-4.7,-2.5, -1.4 %BOLDØsec, p<.05). Putamen activation was decreased postprandially (AUC=-1.2 %BOLDØsec, p<.05). Conclusion: Reward signaling and reward sensitivity was significantly lower under stress, coinciding with increased energy intake from food choice for more crispiness and fullness of taste. The changes in putamen activation may reflect specifically decreased reward prediction sensitivity.
