Long days and crazy schedules lay ahead in your work life.  Perhaps you’re in the middle of one right now.  When days like these come around, it’s important to keep your body operating at its most optimal level.  That way, you are putting yourself in the best position to make clear, confident decisions for whatever tasks and projects that come your way.

Here’s a list of foods that you can consider adding to your diet if you want to keep your tank running longer.  Staying sharp is crucial—especially when you know you’re going to be stuck behind your desk for the better part of 12 hours.

1. Salmon

This is a big winner in the brain food department.  Salmon is rich with Omega-3 fatty acids, which have been proven to improve memory and cognition.  Another perk with this fish is that it can reduce instances of heart disease, cancer and Alzheimer’s.

2. Flax

Think of flax as the plant-based version of Salmon, so it’s a great alternative for vegans and vegetarians.  Along with being a great source for Omega-3s, flax helps lower cholesterol and keep your blood sugar in check.  It’s virtually tasteless, so try sprinkling a ground tablespoon in your oatmeal.  It also comes in an oil version, which is great with smoothies and salad dressings.

3. Blueberries

These berries have a cool antioxidant in them called flavonoids, which have been shown to help improve your ability to learn as well as enhancing your motor skills. Keep them handy for a quick and tasty afternoon snack.

4. Nuts and Seeds

Sunflower seeds, cashews, almonds and others are great sources of Omega-3s and 6.  Plus, nuts have vitamin E, which helps protect the brain from free-radical damage.

5. Eggs

Eggs are known as a great source of protein and they also have choline—a necessary building block for the neurotransmitters in your body that help you concentrate and recall information.

6. Dark Green, Leafy Vegetables

Spinach, kale, chard, and other richly colored green vegetables have B vitamins, which shield your brain from the effects of aging.

7. Chocolate

That’s right! The flavanol in chocolate increases blood flow to the brain, which protects brain cells.  Note though, the darker the chocolate, the better it is for you.  Enjoy a little treat after lunch for an afternoon pick-me-up!
