Yucatan piglets: how perinatal exposure to sugar and fat through mothers’ diets affects behaviour and digestive and metabolic adaptability

The project SweetLip-Kid, financed within the framework of the meta-programme DID’IT, explored what effects early nutritional exposure has on preferences for fatty and/or sugary foods. Cohort studies are carried out in people to better understand the interactions between social and psychological context and how early nutritional exposure affects not only preferences for fatty and sugary foods but also how brain functions develop. Mechanistic investigations carried out in lab animals aim to understand the impact of mothers’ diets during gestation and lactation, as well as the impact of diets fed to offspring until they are weaned on the development of brain structures and peripheral targets, notably taste receptors.

Within the framework of this project, INRA’s research unit for food and digestive, nervous and behavioural adaptation (ADNC), based in Rennes, studies the effects of diet on cognitive capacities (learning and memory) in piglets, which are an effective model for studying food behaviours.

The behaviour of animals whose mothers were fed balanced diets was compared to that of animals whose mothers were fed a diet high in fat and sugar. Initial findings suggest that a perinatal nutritional environment high in fat and sugar promotes preferences for such foods in young animals. Whether or not these preferences persist in adulthood remains to be seen.
