20 Fittest Foods
We count down the absolute best foods to pile on your plate.
6) Spinach
7 calories per cup
Eat 2-3 servings per week
What do button-down dietitians have in common with brawl-happy cartoon sailors? They all love their spinach! And for good reason. One serving of these leafy greens is loaded with fiber, calcium, and virtually your entire day's recommended dosage of beta carotene, a nutrient vital for immune-system health, good vision, but not-as far as we know-huge wrist flexors.
If you can't stand spinach plain, Katherine Tallmadge, R.D., author of Diet Simple, suggests dropping it into burritos, pasta dishes and canned soup.
5) Broccoli
31 calories per cup
Eat 2-3 half-cup servings per week
This fleshy green should be at the top of your list when it comes to vegetables. It's rich with a healthy supply of iron, calcium, fiber, and vitamin C, meaning it's good for the circulatory system, bones, and fighting colds. "As far as vegetables go, this is the one I try hardest to get more guys to eat," says Niki Kubiak, R.D., a private practice nutritionist in Omaha, Neb. Brocco-phobic? Try it on the sly: Slip it into stir-fries, onto pizza, or use raw chunks as a vehicle for your favorite dip.
