Tryptophan-Rich Foods:

Tryptophan is one of the ten essential amino acids and helps our brains produce serotonin, which makes us feel relaxed and in control. Food that has tryptophan can help fight depression, insomnia and anxiety. Foods containing tryptophan include:

-Milk (Vegan? Drink hemp milk- hemp seeds contain all ten essential amino acids!)
-Cashews
-Sunflower Seeds
-Pumpkin Seeds
-Bananas
-Avocados

For the full effect of tryptophan, it is best to eat these items uncooked.

Fruits rich in Antioxidants & Vitamin C:

Fruit like blueberries and oranges are known to contain a high amount of antioxidants and vitamin C, both are helpful for reducing feelings of stress.

Vegetables Rich in Antioxidants & Folic Acid:

Spinach, broccoli and kale are full of folic acid which help produce serotonin (just like tryptophan does).

Chocolate:

Contains anadamine, a chemical naturally found in the brain that is known to brighten our mood and make us feel happier. Enjoy in moderation as the sugar in chocolate might contribute to other issues.

Nuts:

Nuts are rich in minerals, protein and omega-3 fats. Omega-3 is not only good for both your heart and brain, large doses of it have been used to treat clinical depression. Nuts also contain vitamin E, an antioxidant that combats stress. Brazilian nuts such as cashews, almonds and pistachios have been proven to lower blood pressure and calm our nervous system.
