Despite how vital it is, most Americans don't get enough magnesium, which is why it's deemed a shortfall nutrient.

7. Edamame: 99.2 mg, 24% DV

8. Brown Rice: 85.8 mg, 20% DV

Brown rice is a whole grain, meaning it contains all three parts of the grain — the bran, endosperm and germ. The bran and the germ carry the most nutrients, including antioxidants, B vitamins, fiber and protein, according to the Whole Grains Council. When grains are refined (think: white flour and white rice), those nutritious parts are removed, leaving you with just the endosperm's starch.

A diet high in whole grains, like brown rice, is linked to a lower risk of dying from heart disease, according to a March 2015 study in ​JAMA Internal Medicine​.

Plus, cooked brown rice contains 20 percent of the DV for magnesium per cup.

9. Lentils: 71.3 mg, 17% DV

Try it in these protein-packed lentil recipes.

10. Whole-Wheat Pasta: 63.2 mg, 15% DV

Just like brown rice, whole-wheat pasta is a whole grain. That means, compared to white pasta, it provides more nutrition, including fiber (4.6 grams versus 2.2 grams) and protein (8 grams versus 7 grams). The fiber and protein content in whole-wheat pasta can help you feel full longer, according to the American Diabetes Association.

Even more, a 1-cup serving of cooked whole-wheat pasta has 15 percent of the DV for magnesium.

11. Dark Chocolate: 64.8 mg, 15% DV

Why yes, dark chocolate does have health benefits — when you choose the right kind. A 1-ounce serving of 70 to 85 percent dark chocolate (sorry, no milk chocolate) provides heart-healthy antioxidants and 15 percent of the DV for magnesium.

12. Avocados: 58.3 mg, 14% DV

Avocados contain vitamins C and E, protein and more than 50 percent of the DV of fiber as well as 14 percent of the magnesium DV. Try it in these creative avo recipes.

13. Bananas: 40.5 mg, 10% DV

Bananas might be one of the most convenient, nutritious snacks made by nature, and there's no doubt they pair well with so much, including nut butter and honey.
