The 5 Best Brain Foods for Focus

1. Fatty Fish (Salmon) – Brain's Building Block

The Science:
Fatty fish contains omega-3 fatty acids (DHA), essential for brain cell structure and function. Studies show omega-3 consumption supports memory, concentration, and cognitive performance.

2. Blueberries – Nature's Brain Protector

3. Eggs – Cognitive Fuel
