Artichokes

Good for: Energy

If you've been huffing and puffing up the stairs, try these spiky-leafed vegetables. They're loaded with magnesium, a mineral vital for more than 300 biochemical reactions in the body—including generating energy, says Forrest Nielsen, PhD, a U.S. Department of Agriculture research nutritionist. "If you're not getting enough magnesium, your muscles have to work harder to react and you tire more quickly."

About 68% of us aren't getting enough of this mineral. For women, the goal is 320 milligrams (mg) per day. One medium artichoke provides 77 mg of magnesium (and just 60 calories!). Other top sources include nuts, legumes, and whole grains.
