Another rice alternative, quinoa is loved by many for its ability to take on the flavor of whatever the tiny seeds are cooked with. "It's a rich source of fiber, iron thiamin, and folate – all things that may be lacking if someone is eating refined gluten-free food," says Thompson.

As with wild rice, you can cook quinoa like Asian rice (in a rice cooker, even) and substituted in any situation you'd usually use rice. "The one thing you do have to make sure is that you buy it pre-washed," because unwashed quinoa contains a bitter-tasting chemical called saponin.
