Species belonging to the genus Amaranthus have been cultivated for their grains for 8,000 years. [3] Amaranth plants are classified as pseudocereals that are grown for their edible starchy seeds, but they are not in the same botanical family as true cereals, such as wheat and rice. [4] Amaranth species that are still used as a grain are Amaranthus caudatus L., Amaranthus cruentus L., and Amaranthus hypochondriacus L. The yield of grain amaranth is comparable to that of rice or maize.
The grain was a staple food of the Aztecs and an integral part of Aztec religious ceremonies. The cultivation of amaranth was banned by the conquistadores upon their conquest of the Aztec nation. However, the plant has grown as a weed since then, so its genetic base has been largely maintained. Research on grain amaranth began in the United States in the 1970s. By the end of the 1970s, a few thousand acres were being cultivated there, and continue to be cultivated. [5]
Much of the amaranth grain currently grown is sold in health food shops. Grain amaranth is also grown as a food crop in limited areas of Mexico, where it is used to make a candy called alegría (Spanish for joy) at festival times. In other preparations, the grain can be popped like popcorn and then either mixed with honey, or served with milk, dried fruit and nuts like a cold breakfast cereal. Amaranth grain can also be used to extract amaranth oil, a pressed seed oil with commercial uses.
Raw amaranth grain is inedible to humans and cannot be digested because it blocks the absorption of nutrients. [6] [ better source needed ] Thus it has to be prepared and cooked like other grains. In a 100-gram (3+1⁄2-ounce) amount, cooked amaranth provides 430 kilojoules (103 kilocalories) of food energy and is a moderately rich source of dietary minerals, including phosphorus, manganese, and iron. Cooked amaranth is 75% water, 19% carbohydrates, 4% protein, and 2% fat (table). [7] [8]
According to Educational Concerns for Hunger Organization (ECHO), amaranth leaves are nutritious, and "amounts of vitamin C, iron, beta carotene, calcium, folic acid and protein are especially high," however, amaranth leaves contain anti-nutritional factors, including oxalates, nitrates, saponins, and phenolic compounds. [3] Cooking methods such as boiling the leaves in water and then discarding the water may reduce toxic effects. The report also cites a study [9] indicating that "research has shown that consumption of 200 grams of cooked amaranth poses no health problems."
Amaranth grain is high in protein and lysine, an amino acid found in low quantities in other grains. [10] [11] According to the FAO, amaranth grain as a source of protein is "superior in content and quality to traditional cereals". [12] Amaranth grain is deficient in essential amino acids such as leucine and threonine [13] [14] – both of which are present in wheat germ. [15] [16] Amaranth grain is free of gluten, which makes it a viable grain for people with gluten intolerance.

There are about 75 species in the genus Amaranthus. [24] Many species of amaranth grain are hardy plants, showing resistance to changes in pH, salt content, environment, temperature, and drought. [24] Amaranth grains have genetic diversity and adaptive ability. [25]
Some examples of Amaranth species are Amaranthus albus, Amaranthus blitoides, Amaranthus hybridus, Amaranthus palmeri, Amaranthus powellii, Amaranthus retroflexus, Amaranthus spinosus, Amaranthus tuberculatus, and Amaranthus viridis. [24] Amaranthus retroflexus, "pigweed", is a wild amaranth species native to the United States and is considered a weed in the Northeast, Nebraska and Great Plains, South, and West. [26] The name derives from the plant's tendency to sprout where hogs are pasture-fed. Although both its leaves and its seeds are edible, pigweed amaranth has not been cultivated as a food crop.
The Aztecs cultivated amaranth as a staple grain crop in what is now Mexico during the pre-Columbian period. [27] Amaranth was used by the Aztecs for tamales, tortillas, and atole (hot cereal).[ citation needed ] In addition they formed shaped images of their gods with amaranth, agave, and maize during the sacred month of Huitzilopochtli. [27] [28] At the end of the month, the statues were eaten by the families to "take the god into them". [27] When the Spanish prohibited religious acts like this, and imposed the religion of their God who was worshiped through wheat, amaranth cultivation decreased. [27] [28] In current Mexican culture on the Day of the Dead, amaranth seeds are offered as snack foods for the spirits. [29] Edible skulls were historically made with amaranth seeds, although today they are made out of sugar. [29]
Amaranthus is a cosmopolitan group of more than 50 species which make up the genus of annual or short-lived perennial plants collectively known as amaranths. Some of the better known names include "prostrate pigweed" and "love lies bleeding". Some amaranth species are cultivated as leaf vegetables, pseudocereals, and ornamental plants.
The oat, sometimes called the common oat, is a species of cereal grain grown for its seed, which is known by the same name. Oats appear to have been domesticated as a secondary crop, as their seeds resembled those of other cereals closely enough for them to be included by early cultivators. Oats tolerate cold winters less well than cereals such as wheat, barley, and rye, but need less summer heat and more rain, making them important in areas such as Northwest Europe that have cool wet summers. They can tolerate low-nutrient and acid soils. Oats grow thickly and vigorously, allowing them to outcompete many weeds, and compared to other cereals are relatively free from diseases.
The chickpea or chick pea is an annual legume of the family Fabaceae, subfamily Faboideae, cultivated for its edible seeds. Its different types are variously known as gram or Bengal gram; chhola, chhana, chana, or channa; garbanzo or garbanzo bean; or Egyptian pea. It is one of the earliest cultivated legumes, the oldest archaeological evidence of which was found in Syria.
Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth.
Khorasan wheat or Oriental wheat is a tetraploid wheat species. The grain is twice the size of modern-day wheat, and has a rich, nutty flavor.
The winged bean, also known as cigarillas, Goa bean, four-angled bean, four-cornered bean, manila bean, princess bean, star bean, kamrangi bean, pea, or dragon bean, is a tropical herbaceous legume plant.
The germ of a cereal grain is the part that develops into a plant; it is the seed embryo. Along with bran, germ is often a by-product of the milling that produces refined grain products. Cereal grains and their components, such as wheat germ oil, rice bran oil, and maize bran, may be used as a source from which vegetable oil is extracted, or used directly as a food ingredient. The germ is retained as an integral part of whole-grain foods. Non-whole grain methods of milling are intended to isolate the endosperm, which is ground into flour, with removal of both the husk (bran) and the germ. Removal of bran produces a flour with a white rather than a brown color and eliminates fiber. The germ is rich in polyunsaturated fats and so germ removal improves the storage qualities of flour.
Wheatgrass is the freshly sprouted first leaves of the common wheat plant, used as a food, drink, or dietary supplement. Wheatgrass is served freeze dried or fresh, and so it differs from wheat malt, which is convectively dried. Wheatgrass is allowed to grow longer and taller than wheat malt.
Chia seeds are the edible seeds of Salvia hispanica, a flowering plant in the mint family (Lamiaceae) native to central and southern Mexico, or of the related Salvia columbariae, Salvia polystachia, or Salvia tiliifolia. Chia seeds are oval and gray with black and white spots, having a diameter of around 2 millimetres (0.08 in). The seeds are hygroscopic, absorbing up to 12 times their weight in liquid when soaked and developing a mucilaginous coating that gives chia-based foods and beverages a distinctive gel texture.
Amaranthus hybridus, commonly called green amaranth, slim amaranth, smooth amaranth, smooth pigweed, or red amaranth, is a species of annual flowering plant. It is a weedy species found now over much of North America and introduced into Europe and Eurasia.
Amaranthus caudatus is a species of annual flowering plant. It goes by common names such as love-lies-bleeding, pendant amaranth, tassel flower, velvet flower, foxtail amaranth, and quelite.
Amaranthus hypochondriacus is an ornamental plant commonly known as Prince-of-Wales feather or prince's-feather. Originally endemic to Mexico, it is called quelite, bledo and quintonil in Spanish.
Amaranthus retroflexus is a species of flowering plant in the family Amaranthaceae with several common names, including red-root amaranth, redroot pigweed, red-rooted pigweed, common amaranth, pigweed amaranth, and common tumbleweed.
Amaranthus palmeri is a species of edible flowering plant in the amaranth genus. It has several common names, including carelessweed, dioecious amaranth, Palmer's amaranth, Palmer amaranth, and Palmer's pigweed.
Amaranthus cruentus is a flowering plant species that is native from Central Mexico to Nicaragua. It yields a nutritious staple amaranth grain, being one of three Amaranthus species cultivated as a grain source, the other two being Amaranthus hypochondriacus and Amaranthus caudatus. It has several common names, including blood amaranth, red amaranth, purple amaranth, prince's feather, and Mexican grain amaranth.
Vegetables are parts of plants that are consumed by humans or other animals as food. The original meaning is still commonly used and is applied to plants collectively to refer to all edible plant matter, including the flowers, fruits, stems, leaves, roots, and seeds. An alternative definition of the term is applied somewhat arbitrarily, often by culinary and cultural tradition. It may exclude foods derived from some plants that are fruits, flowers, nuts, and cereal grains, but include savoury fruits such as tomatoes and courgettes, flowers such as broccoli, and seeds such as pulses.
A grain is a small, hard, dry fruit (caryopsis) – with or without an attached hull layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and legumes.
A staple food, food staple, or simply staple, is a food that is eaten often and in such quantities that it constitutes a dominant portion of a standard diet for an individual or a population group, supplying a large fraction of energy needs and generally forming a significant proportion of the intake of other nutrients as well. For humans, a staple food of a specific society may be eaten as often as every day or every meal, and most people live on a diet based on just a small variety of food staples. Specific staples vary from place to place, but typically are inexpensive or readily available foods that supply one or more of the macronutrients and micronutrients needed for survival and health: carbohydrates, proteins, fats, minerals, and vitamins. Typical examples include grains, seeds, nuts and root vegetables. Among them, cereals, legumes and tubers account for about 90% of the world's food calorie intake.
Ancient grains is a marketing term used to describe a category of grains and pseudocereals that are purported to have been minimally changed by selective breeding over recent millennia, as opposed to more widespread cereals such as corn, rice and modern varieties of wheat, which are the product of thousands of years of selective breeding. Ancient grains are often marketed as being more nutritious than modern grains, though their health benefits over modern varieties have been disputed by some nutritionists.
Rice is commonly consumed as food around the world. It occurs in long-, medium-, and short-grained types. It is the staple food of over half the world's population.
