When work deadlines begin piling up and your social calendar is booked, the last thing you want to hear is to steer clear of the vending machine. Who has time for healthy eating? But when it comes to combating stress levels, what you eat may actually help relieve your tension. Indeed, some foods may help stabilize blood sugar or, better yet, your emotional response. Here, 12 foods to reach for when you've just about had enough
Green leafy vegetables
It’s tempting to reach for a cheeseburger when stressed, but go green at lunch instead. "Green leafy vegetables like spinach contain folate, which produces dopamine, a pleasure-inducing brain chemical, helping you keep calm," says Heather Mangieri, RDN, a spokesperson for the Academy of Nutrition and Dietetics. A 2012 study in the Journal of Affective Disorders of 2,800 middle-aged and elderly people and found those who consumed the most folate had a lower risk of depression symptoms than those who took in the least. And, a 2013 study from the University of Otago found that college students tended to feel calmer, happier, and more energetic on days they ate more fruits and veggies. It can be hard to tell which came first—upbeat thoughts or healthy eating—but the researchers found that healthy eating seemed to predict a positive mood the next day
As bizarre as it may sound, the bacteria in your gut might be contributing to stress. Research has shown that the brain signals to the gut, which is why stress can inflame gastrointestinal symptoms; communication may flow the other way too, from gut to brain. A 2013 UCLA study among 36 healthy women revealed that consuming probiotics in yogurt reduced brain activity in areas that handle emotion, including stress compared to people who consumed yogurt without probiotics or no yogurt at all. This study was small so more research is needed to confirm the results—but considering yogurt is full of calcium and protein in addition to probiotics, you really can't go wrong by adding more of it to your diet.
When you’re stressed, it can ratchet up anxiety hormones, such as adrenaline and cortisol. "The omega-3 fatty acids in salmon haveanti-inflammatory properties that may help counteract the negative effects of stress hormones," says Lisa Cimperman, RD, of the University Hospitals Case Medical Center and a spokesperson for the Academy of Nutrition and Dietetics. In a study funded by the National Institutes of Health, Oregon State University medical students who took omega-3 supplements had a 20% reduction in anxiety compared to the group given placebo pills. One 3-ounce serving of cooked wild salmon can have more than 2,000 milligrams of omega-3s, double the daily intake recommended by the American Heart Association for people with heart disease.
Calling all chocoholics: a regular healthy indulgence (just a bite, not a whole bar!) of dark chocolate might have the power to regulate your stress levels. "Research has shown that it can reduce your stress hormones, including cortisol," Sass says. "Also, the antioxidants in cocoa trigger the walls of your blood vessels to relax, lowering blood pressure and improving circulation. And finally, dark chocolate contains unique natural substances that create a sense of euphoria similar to the feeling of being in love!" Go for varieties that contain at least 70% cocoa.
Fortified milk is an excellent source of vitamin D, a nutrient that might boost happiness. A 50-year-long study by London's UCL Institute of Child Health found an association between reduced levels of vitamin D and an increased risk of panic and depression among 5,966 men and women. People who had sufficient vitamin D levels had a reduced risk of panic disorders compared to subjects with the lowest levels of vitamin D. Other foods high in vitamin D include salmon, egg yolks, and fortified cereal.
