You might not have guessed this one because you all know far too well how turkey can make us feel on Thanksgiving. Sometimes it can make us really lethargic rather than energized, but this may all be a myth. Turkey meat is high in tryptophan. Our bodies need tryptophan to build up serotonin, a chemical that regulates both hunger and feelings of joy, according to CBS New York. Turkey is also high in protein, so it's perfect for getting your body moving, which is sure to make you feel better.
