Quinoa has been a staple in the Andean regions of South America for thousands of years, but today you can buy this protein-packed superfood at nearly every grocery store. While you'll most often find white, red, and black quinoa, the seed (yes, quinoa is a seed, not a grain!) actually comes in over 250 varieties, ranging in hues from pale yellow to deep violet. Along with its vibrant colors, quinoa boasts a long list of benefits that make it a food worth eating regularly.
