Brain Food: Best Snacks for Focus

Your brain consumes 20% of your body's energy. If you feed it junk, you will get junk results.

1. Walnuts

They literally look like little brains. They are rich in DHA, a type of Omega-3 fatty acid that improves cognitive performance in adults.

2. Blueberries

Known as "Brain Berries," they contain antioxidants that reduce oxidative stress and improve communication between brain cells.

3. Dark Chocolate

Dark chocolate (70% cocoa or more) contains caffeine and flavonoids that boost blood flow to the brain and improve focus for short periods.

4. Water

The most important one. Even 2% dehydration can lead to significant loss of focus and memory. Keep a bottle on your desk.
