Foods high in polysaturated fats found in processed foods

Now that you know what to avoid, let's get down to what you'll be packing in your lunch for work tomorrow.

1. Lean Beef

The B vitamins, zinc, and iron lean beef contains will help settle you down. The omega-3 fatty acids found especially in grass-fed beef are an important part in brain and heart health.

2. Freshwater Fish

Fish like salmon, herring, and tuna, are high in omega-3 fatty acids and vitamins B6 and B12. These essential nutrients promote healthy brain function and elevate your mood -- two important aspects of fighting stress.

3. Turkey

There's a reason you feel so relaxed after eating turkey. The acid known as L-tryptophan is releasing serotonin, a chemical that calms your brain.

4. Avocados

Perfect on tacos, great with eggs, and awesome with everything else, avocados pack a substantial amount of omega-3s. They also contain potassium, which helps lower blood pressure that can spike with stress.

5. Whole Grains

Carbohydrates help brain function. They boost levels of serotonin, a feel-good chemical in the brain. Whole grains provide longer-lasting energy than processed flours.

6. Almonds & Sunflower Seeds

These easy-to-find crunchy guys can cut through stress like a ninja. They contain riboflavin, zinc, magnesium, vitamin E, and other important vitamins and minerals. Snacking on seeds and nuts throughout the day can prevent stress from building up. To maximize nutrition benefits, opt for raw over roasted.

7. Dark Green Leafy Vegetables

Greens carry lots of B vitamins, including folic acid, which is important for easing symptoms of depression, relieving stress, and reducing anxiety. Look for kale, spinach, arugula, and Swiss chard.
