Abstract
Scope: Increasing scientific evidence is validating the use of dietary strategiesto support and improve brain health throughout the lifespan, with tailorednutritional interventions catering for specific life stages. Dietary phospholipidsupplementations in early life and adulthood are shown to alleviate some ofthe behavioral consequences associated with chronic stress. This study aimsto explore the protective effects of a tailored phospholipid-enriched buttermilkon behavioral and endocrine responses induced by chronic psychosocialstress in adulthood, and to compare these effects according to the life stage atwhich the supplementation is started.Methods and Results: A novel developed phospholipid-enriched dairy productis assessed for its effects on social, anxiety- and depressive-like behaviors, aswell as the stress response and cognitive performance following chronicpsychosocial stress in C57BL/6J mice, with supplementation beginning inadulthood or early life. Milk phospholipid supplementation from birth protectsadult mice against chronic stress-induced changes in endocrine response to asubsequent acute stressor and reduces innate anxiety-like behavior innon-stressed animals. When starting in adulthood, the dietary interventionreverses the anxiety-like phenotype caused by chronic stress exposure.Conclusion: Dairy-derived phospholipids exert differential protective effectsagainst chronic psychosocial stress depending on the targeted life stage andduration of the dietary supplementation.
