CHOCOLATE: GOING BEYO ND PLEASANT TASTE DIRECTLY TO THE IMPROVEMENT OF DEPRESSION

Resumo

Introduction: Depression is a multifactorial mental disorder with i ncreasing interest in modifiable lifestyle factors, particularly dietary patterns. Chocolate, a widely consumed food rich in bioactive compounds such as polyphenols and methylxanthines, has been investigated for its potential influence on mood and depressi ve symptoms, although current evidence remains heterogeneous. Objective: The aim of thi study is to investigate the relationship between chocolate consumption and depressive symptoms, as well as the underlying biological mechanisms involved. Methods: This integrative literature review was conducted through searches in the PubMed database using the descriptors chocolate and depression. Filters for free full - text availability and publication within the last five years were initially applied, followed by expa nsion to the last ten years to increase the number of eligible studies. Clinical and observational studies addressing the association between chocolate consumption, dietary patterns, and depressive outcomes were included, totaling six selected articles for qualitative analysis. The selected articles involved multi- ethnicpopulations, middle-aged and older adults, and menopausal women. Results: Evidence from observational studies, involving men and women from different backgrounds, indicates that dietary patterns characterized by high intake of sugar, saturated fat, and ultra -processed foods are consistently associated with a higher prevalence of depressive symptoms. Chocolate consumption, particularly when integrated into such dietary patterns, has been assoc iated with an increased likelihood of depression in some populations; however, this relationship appears to be influenced by confounding factors such as overall diet quality, socioeconomic variables, and lifestyle habits. Conversely, findings from a randomized clinical trial demonstrated that daily consumption of high- cocoa dark chocolate significantly reduced depression scores, suggesting a potential beneficial effect under controlled conditions. Proposed mechanisms include the antioxidant and anti - inflammatory properties of cocoa polyphenols, modulation of neurotransmitter pathways, reduction of oxidative stress, and improvements in cerebral blood flow. Furthermore, dietary patterns rich in fruits, vegetables, and nutrient-dense foods were consistently associated with lower rates of depressive symptoms. Conclusion: The relationship between chocolate consumption and depression is complex and appears to depend on both the type of chocolate and the broader dietary context. While unhealthy dietary patterns are associated with increased depressive symptoms, dark chocolate may exert protective effects due to its bioactive compounds. Further well -designed clinical trials are necessary to clarify causality and support evidence -based dietary recommendations.
