The Relationship between Fat Consumption and Mood Enhancement: A Comprehensive Review

Abstract

Background: The role of fat consumption in human health has been the subject of much debate and research. While the association between fat intake and cardiovascular health has been well-established, the relationship between fat consumption and mood remains relatively underexplored. This review aims to provide a comprehensive overview of the literature examining the link between dietary fat intake and mood enhancement. Methods: A systematic review of the literature was conducted, focusing on studies that investigated the effects of different types of dietary fat on mood states. Studies were included if they were published between January 2000 and September 2021, and reported on the relationship between fat consumption and mood outcomes in humans. Results: The review identified a number of studies suggesting a positive association between dietary fat intake and mood enhancement. The consumption of omega-3 fatty acids, in particular, was found to have a strong association with improved mood, reduced depression, and enhanced cognitive function. The evidence for saturated fat and mood outcomes was less consistent, with some studies indicating potential detrimental effects on mood. Conclusion: The available evidence suggests that fat consumption, particularly omega-3 fatty acids, may play a role in mood enhancement. However, further research is needed to establish causality and the potential implications for public health and nutrition recommendations.
