A clear mind is often linked to a healthy diet rich in nutrients. Here are some foods that may help support cognitive function and promote mental clarity:

1. *Fatty Fish*: Fatty fish like salmon, sardines, and tuna are rich in omega-3 fatty acids, which support brain health and may improve focus and memory.
2. *Nuts and Seeds*: Nuts and seeds like walnuts, almonds, and pumpkin seeds are rich in healthy fats and antioxidants, which may help reduce inflammation and promote cognitive function.
3. *Leafy Greens*: Leafy greens like spinach, kale, and collard greens are rich in folate, which is essential for cognitive function and may help reduce the risk of dementia.
4. *Berries*: Berries like blueberries, strawberries, and raspberries are rich in antioxidants and may help reduce inflammation and promote cognitive function.
5. *Fermented Foods*: Fermented foods like kimchi, sauerkraut, and kefir contain probiotics, which may help support gut health and promote cognitive function.
6. *Whole Grains*: Whole grains like brown rice, quinoa, and whole wheat bread provide sustained energy and may help promote cognitive function.
7. *Legumes*: Legumes like lentils, chickpeas, and black beans are rich in fiber, protein, and complex carbohydrates, which may help support cognitive function.
8. *Green Tea*: Green tea contains an amino acid called L-theanine, which may help promote relaxation and reduce stress levels.
9. *Dark Chocolate*: Dark chocolate contains flavonoids, which may help improve blood flow to the brain and promote cognitive function.

In addition to incorporating these foods into your diet, it’s also important to:
