19. Sardines
Sardines are among the fatty fishes that are rich in omega-3 fatty acid which is known to diminish episodes of depression. While many other types of seafood are rich in omega-3 fatty acids, sardines are more interesting as they can be added into Greek salad or even baked to form a small pizza. Sardines are therefore both healthy and versatile.
20. Mozzarella Cheese
Whenever one mentions tryptophan, the first thing that comes to mind is tryptophan. However, there are more foods that are rich in amino acids aside from just turkey. A good example is Mozzarella cheese which is rich in tryptophan. Tryptophan is known for playing a huge role in the production of serotonin, improving your mood and in your overall cognition. This should come as great news and encourage you to melt some of this cheese on some bread in your toaster or instead, sprinkle some on your salad.
