It helps you snooze and eases pain

Lately it seems every insomniac is popping magnesium like crazy. While it won’t knock you out the way a sleeping pill might, the nutrient has been shown to help muscles relax and is also popular among athletes for soothing achy muscles, says Blatner. And magnesium, which may help quiet areas of the brain that keep us awake, could have a calming effect, helping to relieve mild anxiety that keeps you up at night. There’s also evidence that magnesium may ward off migraines.

Where to get it

Dietary surveys consistently show that Americans don’t get enough magnesium. That could be because magnesium is mostly found in high-fiber foods (veggies, brown rice), which have been largely replaced by refined or processed foods in the typical American diet. In addition to fiber, make sure you eat good fats in the form of seeds and nuts (including nut butters), which are some of the best sources of magnesium.

Dish it up

For a salad... Toss a few handfuls of fresh spinach with vinaigrette. Top with 1 cup black beans and 1⁄2 avocado, sliced.
For a snack... Stir pumpkin seeds, banana slices, 1 to 2 chopped dark chocolate squares, and a little cinnamon and maple syrup into a single-serve container of plain Greek yogurt.
For a side... Sauté chopped onions and Swiss chard in 1⁄4 cup veggie broth with garlic, fresh grated ginger, and crushed red pepper.
