Title<\/h3>\n

“Feed your Teen Spirit”: Differential impact of unbalanced diets during adolescence on action control processes\u201d<\/em><\/p>\n

Abstract<\/h3>\n

Appropriate control of feeding and food choice is essential for survival and for a healthy life. However, the increased availability of energy-rich unbalanced diets in modern societies drives unhealthy dietary habits and increases obesity and associated disorders, such as cardiovascular diseases or type 2 diabetes. As this incidence is now increasingly affecting children and adolescents, it appears crucial to understand how such unhealthy diets may impact cognitive and brain development and lead to long-term and long-lasting adaptive control of food choices.<\/p>\n

In this talk, I will present new unpublished data from different projects aiming at exploring the long-term cognitive and behavioural impact of the exposure to different diets, all unbalanced in either carbohydrate, fat or protein, specifically during adolescence.<\/p>\n

To investigate the impact of different adolescent diets on action control, we used specific behavioural approaches based on associative learning (Pavlovian and instrumental conditioning) in a mouse model. Our initial results demonstrate a complex sex- and nutrient-dependent impact of adolescent unbalanced diet on the ability to correctly control food-seeking behaviour according to changes in the value of the food (outcome devaluation), changes in action-outcome relationships (reversal learning and contingency degradation) or in response to food-related environmental stimuli (Pavlovian-instrumental transfer). These results may lead to a better understanding of the effect of modern lifestyles on feeding behaviour and metabolic\/mental health.<\/p>\n
