Cereal in the context of Roasted grain beverage

Mesopotamia is a historical region of West Asia situated within the Tigris–Euphrates river system, in the northern part of the Fertile Crescent. It corresponds roughly to the territory of modern Iraq and forms the eastern geographic boundary of the modern Middle East. Just beyond it lies southwestern Iran, where the region transitions into the Persian plateau, marking the shift from the Arab world to Iran. In the broader sense, the historical region of Mesopotamia also includes parts of present-day Iran (southwest), Turkey (southeast), Syria (northeast), and Kuwait.

Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. It has been identified as having "inspired some of the most important developments in human history, including the invention of the wheel, the planting of the first cereal crops, the development of cursive script, mathematics, astronomy, and agriculture". It is recognised as the cradle of some of the world's earliest civilizations.

This is a list of Neolithic cultures of China that have been unearthed by archaeologists. They are sorted in chronological order from earliest to latest and are followed by a schematic visualization of these cultures.

It would seem that the definition of Neolithic in China is undergoing changes. The discovery in 2012 of pottery about 20,000 years BC indicates that this measure alone can no longer be used to define the period. It will fall to the more difficult task of determining when cereal domestication started.

Agriculture in West Asia can be traced back to the early Neolithic in the Near East, between 10,000 and 8,000 BC, when a series of domestications by human communities took place, primarily involving a few plants (cereals and legumes) and animals (sheep, goats, bos, and pigs). In these regions, this gradually led to the introduction of agriculture and animal husbandry and their expansion to other parts of the world. The Neolithic is commonly defined as the transition from a "predatory" economy of hunter-gatherers (or "collectors") to a "productive" economy of farmer-breeders, which places the question of plant and animal domestication at the heart of the upheavals brought about by this period.

Farming and livestock breeding appeared in areas of rich biological diversity, where domesticated plants and animals were found in the wild. These regions also contain a large number of food resources in their natural state. Before their domestication, domesticated plants and animals were exploited in the form of gathering and hunting, with the methods and techniques required for domestication already known at the end of the Palaeolithic. Between 9500 and 8500 B.C., "pre-domestic" forms of agriculture were introduced; plants still had a wild character, but their reproduction was controlled by humans. Control of wild animals also began in the same period. These practices gradually led to the emergence of domesticated plant and animal species, which are distinct from the wild forms from which they derive. From a biological point of view, these domesticated species undergo a transition from natural selection to artificial selection by humans. This indicates the conclusion of the domestication process in the period between 8500 BC and 8000 BC. From this point onwards, village communities relied more on the "agro-pastoral" system, combining agriculture and animal husbandry, and less on hunting, fishing, and gathering practices.

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.

After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (plantains, breadfruit, etc.) and tubers (sweet potatoes, cassava, and more). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported by rail or ship, stored for long periods in silos, and milled for flour or pressed for oil. Thus, the grain market is a major global agricultural market that includes crops such as maize, rice, soybeans, wheat and other grains.

The Grass Crown (Latin: corona graminea) or Blockade Crown (corona obsidionalis) was the highest and rarest of all military decorations in the Roman Republic and early Roman Empire. It was presented only to a general, commander, or officer whose actions saved a legion or the entire army. One example of actions leading to awarding of a grass crown would be a general who broke the blockade around a beleaguered Roman army. The crown took the form of a chaplet made from plant materials taken from the battlefield, including grasses, flowers, and various cereals such as wheat; it was presented to the general by the army he had saved.

Wheat is a group of wild and domesticated grasses of the genus Triticum (/ˈtrɪtɪkəm/). They are cultivated for their cereal grains, which are staple foods around the world. Well-known wheat species and hybrids include the most widely grown common wheat (T. aestivum), spelt, durum, emmer, einkorn, and Khorasan or Kamut. The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BC.

Wheat is grown on a larger area of land than any other food crop (220.7 million hectares or 545 million acres in 2021). World trade in wheat is greater than that of all other crops combined. In 2021, world wheat production was 771 million tonnes (850 million short tons), making it the second most-produced cereal after maize (known as corn in North America and Australia; wheat is often called corn in other countries including Britain). Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing because of the usefulness of gluten to the food industry.

The Qadan culture (13000-9000 BCE) was an ancient culture that, archaeological evidence suggests, originated in Nubia approximately 15,000 years ago. This way of life is estimated to have persisted for approximately 4,000 years, and was characterized by hunting, as well as a unique approach to food gathering that incorporated the preparation and consumption of wild grasses and grains. Systematic efforts were made by the Qadan people to water, care for, and harvest local plant life, but grains were not planted in ordered rows.

Sites from this period span from the Second Cataract of the Nile to Tushka, situated approximately 250 kilometers upriver from Aswan.

Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin.The development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter-gatherer lifestyles to permanent settlements and farming.

Wild grains were collected and eaten from at least 104,000 years ago. However, domestication did not occur until much later. The earliest evidence of small-scale cultivation of edible grasses is from around 21,000 BC with the Ohalo II people on the shores of the Sea of Galilee. By around 9500 BC, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, peas, lentils, bitter vetch, chickpeas, and flax – were cultivated in the Levant. Rye may have been cultivated earlier, but this claim remains controversial. Regardless, rye's spread from Southwest Asia to the Atlantic was independent of the Neolithic founder crop package. Rice was domesticated in China by 6200 BC with earliest known cultivation from 5700 BC, followed by mung, soy and azuki beans. Rice was also independently domesticated in West Africa and cultivated by 1000 BC. Pigs were domesticated in Mesopotamia around 11,000 years ago, followed by sheep. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and India around 8500 BC. Camels were domesticated late, perhaps around 3000 BC.

Sorghum bicolor, commonly called sorghum (/ˈsɔːrɡəm/) and also known as broomcorn, great millet, Indian millet, Guinea corn, or jowar, is a species in the grass genus Sorghum cultivated chiefly for its grain. The grain is used as food by humans, while the plant is used for animal feed and ethanol production. The stalk of sweet sorghum varieties, called sorgo or sorgho and taller than those grown for grain, can be used for forage or silage or crushed for juice that can be boiled down into edible syrup or fermented into ethanol.

Sorghum originated and was domesticated in Sudan, and is widely cultivated in tropical and subtropical regions. It is the world's fifth-most important cereal crop after rice, wheat, maize, and barley. It is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 metres (13 ft) high. The grain is small, 2 to 4 millimetres (0.08 to 0.2 in) in diameter.

The oat (Avena sativa), sometimes called the common oat, is a species of cereal grass grown for fodder and for its seed, which is known by the same name (usually in the plural). 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.

Oats are used for human consumption as oatmeal, including as steel cut oats or rolled oats. Global production is dominated by Canada and Russia; global trade is a small part of production, most of the grain being consumed within the producing countries. Oats are a nutrient-rich food associated with lower blood cholesterol and reduced risk of human heart disease when consumed regularly. One of the most common uses of oats is as livestock feed; the crop can also be grown as groundcover and ploughed in as a green manure.

Millets (/ˈmɪlɪts/) are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most millets belong to the tribe Paniceae.

Millets are important crops in the semiarid tropics of Asia and Africa, especially in India, Mali, Nigeria, and Niger, with 97% of production in developing countries. The crop is favoured for its productivity and short growing season under hot dry conditions. The millets are sometimes understood to include the widely cultivated sorghum; apart from that, pearl millet is the most commonly cultivated of the millets. Finger millet, proso millet, barnyard millet, little millet, kodo millet, browntop millet and foxtail millet are other important crop species.Millets may have been consumed by humans for about 7,000 years and potentially had "a pivotal role in the rise of multi-crop agriculture and settled farming societies".

Poaceae (/poʊˈeɪsi.iː, -ˌaɪ/ poh-AY-see-e(y)e), also called Gramineae (/ɡrəˈmɪni.iː, -ˌaɪ/ grə-MIN-ee-e(y)e), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as true grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. Poaceae is the most well-known family within the informal group known as grass.

With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae.

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 (cereals and legumes), seeds, nuts and root vegetables (tubers and roots). Among them, cereals (rice, wheat, oat, maize, etc.), legumes (lentils and beans) and tubers (e.g. potato, taro and yam) account for about 90% of the world's food calorie intake.

Early agricultural civilizations valued the crop foods that they established as staples because, in addition to providing necessary nutrition, they generally are suitable for storage over long periods of time without decay. Such nonperishable foods are the only possible staples during seasons of shortage, such as dry seasons or cold temperate winters, against which times harvests have been stored. During seasons of surplus, wider choices of foods may be available.

Buckwheat (Fagopyrum esculentum) or common buckwheat is a flowering plant in the knotweed family Polygonaceae cultivated for its grain-like seeds and as a cover crop. Buckwheat cultivation originated around the 6th millennium BC in the region of what is now Yunnan Province in southwestern China. The name "buckwheat" is used for several other species, such as Fagopyrum tataricum, a domesticated food plant raised in Asia.

Despite its name, buckwheat is not closely related to wheat, nor is it a cereal or a member of the grass family. It is related to sorrel, knotweed, and rhubarb. Buckwheat is considered a pseudocereal because the high starch content of the seeds enables buckwheat to be cooked and consumed like a cereal.

A pseudocereal or pseudograin is one of any non-grasses that are used in much the same way as cereals (true cereals are grasses). Pseudocereals can be further distinguished from other non-cereal staple crops (such as potatoes) by their being processed like a cereal: their seed can be ground into flour and otherwise used as a cereal. Prominent examples of pseudocereals include amaranth (love-lies-bleeding, red amaranth, Prince-of-Wales-feather), quinoa, and buckwheat. The pseudocereals have a good nutritional profile, with high levels of essential amino acids, essential fatty acids, minerals, and some vitamins. The starch in pseudocereals has small granules and low amylose content (except for buckwheat), which gives it similar properties to waxy-type cereal starches. The functional properties of pseudocereals, such as high viscosity, water-binding capacity, swelling capability, and freeze-thaw stability, are determined by their starch properties and seed morphology. Pseudocereals are gluten-free, and they are used to make 100% gluten-free products, which has increased their popularity.

In ancient Roman religion, Ceres (/ˈsɪəriːz/ SEER-eez, Latin: [ˈkɛreːs]) was a goddess of agriculture, grain crops, fertility and motherly relationships. She was originally the central deity in Rome's so-called plebeian or Aventine Triad, then was paired with her daughter Proserpina in what Romans described as "the Greek rites of Ceres". Her seven-day April festival of Cerealia included the popular Ludi Ceriales (Ceres's games). She was also honoured in the May lustration (lustratio) of the fields at the Ambarvalia festival: at harvesttime: and during Roman marriages and funeral rites. She is usually depicted as a mature woman.

Ceres is the only one of Rome's many agricultural deities to be listed among the Dii Consentes, Rome's equivalent to the Twelve Olympians of Greek mythology. The Romans saw her as the counterpart of the Greek goddess Demeter, whose mythology was reinterpreted for Ceres in Roman art and literature.

The grain trade refers to the local and international trade in cereals such as wheat, barley, maize, rice, and other food grains. Grain is an important trade item because it is easily stored and transported with limited spoilage, unlike other agricultural products. Healthy grain supply and trade is important to many societies, providing a caloric base for most food systems as well as important role in animal feed for animal agriculture.

The grain trade began as early as agricultural settlement, identified in many of the early cultures that adopted sedentary farming. Major societal changes have been directly connected to the grain trade, such as the fall of the Roman Empire. From the early modern period onward, grain trade has been an important part of colonial expansion and foreign policy. The geopolitical dominance of countries like Australia, the United States, Canada, and the Soviet Union during the 20th century was connected with their status as grain surplus countries.

Oryza sativa, having the common name Asian cultivated rice, is the much more common of the two rice species cultivated as a cereal, the other species being O. glaberrima, African rice. It was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago.

Oryza sativa belongs to the genus Oryza and the BOP clade in the grass family Poaceae. With a genome consisting of 430 Mbp across 12 chromosomes, it is renowned for being easy to genetically modify and is a model organism for the study of the biology of cereals and monocots.

A gristmill (also known as a grist mill, corn mill, flour mill, feed mill or feedmill) grinds cereal grain into flour and middlings. The term can refer to either the grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding.
