Two handfuls of cashews each day may keep depression at bay. A growing body of research has found that in lieu of taking a prescription drug, some people can turn to foods that are high in tryptophans, like cashews. Depressive episodes are often triggered when the body drops in serotonin and tryptophans can boost it again, but people tend to turn to nutrition as a last resort. One more natural source of tryptophan is cashews. “Several handfuls of cashews provide 1,000-2,000 milligrams of tryptophan, which will work as well as prescription antidepressants,” says Dr. Andrew Saul, a therapeutic nutritionist and editor-in-chief of Orthomolecular Medicine News Service. The body turns tryptophan into serotonin, a major contributor to feelings of sexual desire, good mood, and healthy sleep.
The high levels of magnesium and vitamin B6 found in cashews may also help to stabilize mood. Approximately five ounces of cashews a day will provide a middle-aged man with his daily-required magnesium intake, a nutrient that, when low, can trigger mild depression. Vitamin B6 lends a hand to converting tryptophan into serotonin and helps magnesium enter into the body’s cells. It’s likely a trio of nutrients that help with depression. “You don’t want to think that one individual nutrient is the magic bullet,” says Saul.
