Emerging research in nutritional psychiatry reveals significant connections between diet and cognition. What you eat directly influences the brain chemistry underlying cognition.
The Gut-Brain Connection and Cognition
The gut microbiome produces neurotransmitters that influence cognition. A diet rich in fiber and fermented foods supports a healthy microbiome.
Foods That May Help Cognition
- Omega-3 fatty acids (salmon, walnuts, flaxseed): Anti-inflammatory effects that support brain function
- Complex carbohydrates: Stabilize blood sugar and support serotonin production
- Leafy greens: Rich in folate, important for neurotransmitter synthesis
- Fermented foods: Support gut microbiome health linked to mood regulation
Foods to Limit with Cognition
- Highly processed foods increase inflammation linked to cognition
- Excessive sugar causes blood sugar swings that worsen mood instability
- Caffeine can amplify anxiety and disrupt sleep in cognition
- Alcohol worsens cognition despite short-term apparent relief
Practical Dietary Changes for Cognition
Small, consistent dietary changes compound over time. Focus on adding beneficial foods rather than restricting.
