The yield of grain amaranth is comparable to [[rice]] or [[maize]]. It was a [[staple food]] of the [[Aztec]]s, and was used as an integral part of [[Aztec]] religious ceremonies. Its [[cultivation]] was banned by the [[conquistadores]] in [[1516]]. Because the plant has continued to grow as a [[weed]] since that time, its [[Genetics|genetic]] base has been largely maintained. Research on grain amaranth began in the [[United States|US]] in the [[1970s]]. By the end of the [[1970s]], a few thousand acres were being cultivated.<ref>{{cite web

Grain amaranth is also grown as a food crop in limited amounts in [[Mexico]], where it is used to make a [[candy]] called [[Alegria (candy)|alegría]] ([[Spanish language|Spanish]]: "happiness") at [[festival]] times. The grains are popped, and mixed with honey.
Amaranth grain can also be used to extract [[amaranth oil]] - a particularly valued [[Vegetable fats and oils|pressed seed oil]] with many commercial uses.
