What family does quinoa belong to?

Quinoa is classified within the Amaranthaceae family, which includes plants that are related to both spinach and beets. Particularly, it is considered a member of the spinach family, highlighting its close botanical relationship with these leafy greens. Quinoa is often valued for its high nutritional profile, including being a complete protein source and rich in vitamins and minerals.

Regarding the other options, while quinoa does share some characteristics with members of the mustard family (Brassicaceae), cabbage family (also Brassicaceae), and legume family (Fabaceae) due to its use as a grain and its cultivation practices, its specific family classification distinctly places it alongside spinach in the Amaranthaceae family. This commonality signifies a closer genetic relationship, which is why identifying quinoa as part of the spinach family is accurate.
