Though technically a seed, Quinoa is classified as a whole grain and is a good source of plant protein and fiber. One cup cooked provides about 8 grams of protein and 5 grams of fiber.

Quinoa is also naturally gluten-free and can be eaten safely if one has gluten intolerance such as celiac disease.
