42. Cashews
Like many other nuts on this list, cashews contain depression-fighting tryptophan that helps boost mood stability and serotonin production. Their high level of magnesium also supports thyroid health. Plus, cashews have lots of B vitamins that boost metabolism and provide energy to send mood-stabilizing hormones where they need to go.

Research shows that just a handful or two of cashews is more than enough tryptophan to help stabilize mood, as well as people with anxiety and depression. Some other benefits include improved cholesterol, heart health, and blood sugar levels because of the healthy fats. Cashews also contain fiber that supports digestive health.
