Healthy Dietary Patterns
Healthy dietary patterns, such as the Mediterranean diet—rich in fruits, vegetables, whole grains, nuts, and fish—are linked to a reduced risk of depression and anxiety. These diets also contribute to better cognitive performance and slower cognitive decline.
Unhealthy Dietary Patterns
In contrast, unhealthy dietary patterns, such as Western diets high in saturated fats and sugars, are associated with an increased risk of depression and anxiety, as well as poorer cognitive function.
Nutrient Intake and Cognitive Health
Nutrient intake from healthy diets reduces inflammation, improves vascular health, and supports neurogenesis, all of which benefit cognitive function. Diets high in antioxidants, polyphenols, and omega-3 fatty acids may help regulate neurotransmitter systems involved in mood and cognition. Additionally, healthy diets support a diverse gut microbiome, which is increasingly recognised as influencing both mood and cognitive health.
Research Findings
Research, including randomised controlled trials and meta-analyses, shows that dietary interventions can significantly reduce depressive symptoms. Individuals with higher adherence to healthy dietary patterns experience lower rates of depression and anxiety, along with superior cognitive performance compared to those following less healthy diets.
Conclusion
Dietary modification is a valuable strategy for maintaining cognitive health and managing mood disorders. Interventions promoting the Mediterranean diet or similar dietary patterns could help mitigate the negative impact of depression and anxiety on cognitive function and support healthspan in older adults.
