Almonds have huge amounts of health benefits, especially when it comes to anxiety. They contain zinc, which helps to keep the mood balanced, as well as healthy fats for neurotransmitters and iron for brain activity. While a tired brain may not seem like an immediate link to anxiety, a lack of mental energy can actually cause you to become more anxious while in your fatigued state of mind.You know how everybody wants to take a nice, long nap after Thanksgiving dinner? That same tryptophan that puts everyone to sleep also serves as a precursor to serotonin, a neurotransmitter that's believed to act as a mood stabilizer. If you want to calm yourself down, then turkey can be a great go-to.
