Superfood No 3: Pumpkin seeds
One ounce of pumpkin seeds contains 37 percent of your daily magnesium, a mineral linked with healthy sleep. “Magnesium activates the neurotransmitter GABA [gamma-aminobutyric acid], which helps calm the nervous system,” says Cassetty, who likes to think of this as activating the on/off switch for your brain. “Magnesium is part of the mechanics that relax your brain and body so you can fall asleep at night,” she says. Studies in older adults have shown that magnesium supplementation can improve sleep quality and duration.
Superfood No. 4: Cheese
If a warm glass of milk doesn’t sound appealing, grab a few cubes of cheese. “This protein-packed snack is also full of calcium, magnesium and tryptophan, all of which are necessary for a good night’s sleep,” says Taub-Dix. A2013 study published in the journalGeneral Dentistryfound that eating cheese increases your saliva production and may therefore help ward off cavities. Another study found that eating two tablespoons of cottage cheese 30 to 60 minutes before bed supports metabolism and muscle recovery.
And while cheese used to have a reputation as a source of nightmares, studies have proven that to be false. “It’s not a good idea to eat a whole package of cheese before turning in, but a small portion paired with a whole-grain carb (a slice of bread or a few crackers) can help rock you to sleep since carbs stimulate the release of serotonin, a neurotransmitter that helps bring on that ahhh feeling,” Taub-Dixsays.
Superfood No 5: Tart cherry juice
“Tart cherries have a high dietary melatonin concentration and have also been shown to exhibit anti-inflammatory characteristics that may be beneficial in improving sleep quality,” says Kristine Dilley, a registered dietitian at theOhioState University Wexner Medical Center. One small Louisiana State University study found that drinking 8 ounces of tart cherry juice twice a day for two weeks increased both sleep time and sleep efficiency in adults with insomnia. Another study had 20 volunteers drink tart cherry juice or a placebo for seven days. Those who drank the cherry juice had significantly higher melatonin levels than those who didn’t.
As tart cherry juice contains natural sugars, Dilley warns that individuals with diabetes or conditions that make them sensitive to sugar intake should consult their physician before adding this to their daily routine. And when purchasing, opt for brands without added sugars.
Superfood No 6: Tea
Chamomile tea has been used for decades as a sleep aid for its calming and antioxidant properties. “It comes from a flower and is full of calming scents,” says Dana Ellis Hunnes,asenior clinical dietitian at the UCLA Medical Center, assistant professor at UCLA Fielding School of Public Health and author ofRecipefor Survival.Chamomile also contains apigenin, a flavonoid (plant nutrient) that promotes sleepiness, she adds. A2017study that examined the effect of chamomile extract on the sleep habits of adults age 60 and older found that when compared toaplacebo group, those who drank chamomile had significantly improved sleep quality.
But this classic isn’t the only type of herbal tea to try. Low-caffeine green tea contains theanine, an amino acid that research has found can help lower stress and significantly improve sleep quality. “And tea made from the herb lemon balm contains naturally occurring oils with terpenes, organic compounds that can promote relaxation and better sleep,” Hunnes says.
Superfood No. 7: Rice
One study of Japanese men and women found that a high dietary glycemic index and high rice consumption was significantly associated with good sleep. The study also looked at bread, which was not associated with sleep quality, and found that noodles were linked to poor sleep.
Dilley recommends brown rice, which is higher in fiber. “In a study published in theJournal of Clinical Sleep Medicine,eating a higher-fiber diet was associated with less nighttime awakenings and more restorative slow-wave sleep,” she says. This effect, she says, could be due to the fact that fiber helps prevent blood sugar spikes that may lower melatonin. Sylvia Melendez-Klinger,a registered dietitian and founder of Hispanic Food Communications, recommends trying a rice-dairy combo of rice pudding with no added sugar or rice crackers or rice cakes with a glass of warm milk, as another optimal bedtime snack.
Superfood No. 8: Nuts
“Many nuts such as almonds, walnuts and pistachios have melatonin, along with magnesium and zinc, which together can help people get a better night's sleep,” Melendez-Klinger says.Spread some nut butter on a rice cake for the ultimate before-bed snack.(Basic peanut butter and crackers works, too.) Or you could reach for a handful of Brazil nuts. A study by the University of Pennsylvania and the University of Chicago suggested that people who sleep less than five hours a night do not consume enough of the mineral selenium. “Thankfully,Brazil nutsare chock full of it, and eating just two per day can ensure your body is meeting the minimum requirements for this nutrient,” says Kaytee Hadley, a dietitian, health coach and founder of Holistic Health & Wellness.
Superfood No. 9: Yogurt
Researchsuggests that fermented dairy foods, like yogurt, may be helpful for improving sleep quality. “Yogurt is rich in GABA, an amino acid that helps you relax and sleep better,” says Cassetty, who likes Greek yogurt for its added protein boost. Plus, she notes that fermented foods help increase microbial diversity, which is alsolinked tobetter sleep. But watch out for added sugars when choosing yogurt. “I’ve seen some versions with as much added sugar as a small scoop of ice cream,” Cassettysays.“There are many concerns with a sugary diet, but one is that it can contribute to sleep problems.”In fact, a 2022studyof university studentsfoundthat poor sleep quality was significantly related to higher added sugar intake.
An Eating Style to Help You Snooze
Withthe Mediterranean dieteating plan, your plate is mostly filled with plantsproducts, like whole grains, veggies, fruits, nutsand seeds. You’ll also eat smaller portions of animal foods, like Greek yogurt, eggsand poultry. “The Mediterranean diet is also lower in sweets than the American diet,”Cassettysays.Research in 2020foundthat this dietary pattern is tied to better sleep quality and efficiency in women.And a recent review of studies on sleep and diet found similar results.
“Dietary patterns that include more fruits and vegetables and less sugary foods are associated with lower risk of insomnia and short sleep,” says study author Marie-Pierre St-Onge,associate professor ofnutritional medicineanddirectorof theColumbia University Irving Medical CenterSleep Center of Excellence. “People who follow a diet that has more fiber, less saturated fat, and more legumes have better sleep quality and fall asleep more quickly at night.” In fact, one of the studies that the paper looked at found that thetimeto fall asleep was reduced by 40percentin adults when their diet contained more fiber and less saturated fat.An added benefit beyond restful sleep: Research has linked the Mediterranean diet to improvedheartandbrainhealth.
“What’sgreat about the Mediterranean diet eating pattern is that it can be adapted to any cultural cuisine,”Cassettysays. “You can think of it as an80/20 plant-based dietand load up on your favorite whole or minimally processed plant foods.”
