Indonesia the Republic of Indonesia, is a country in Southeast Asia, between the Indian and Pacific oceans. It is the world's largest island country, with more than seventeen thousand islands, at 1,904,569 square kilometres, the 14th largest by land area and the 7th largest in combined sea and land area. With over 261 million people, it is the world's 4th most populous country as well as the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population; the sovereign state is a constitutional republic with an elected parliament. It has 34 provinces. Jakarta, the country's capital, is the second most populous urban area in the world; the country shares land borders with Papua New Guinea, East Timor, the eastern part of Malaysia. Other neighbouring countries include Singapore, the Philippines, Australia and India's Andaman and Nicobar Islands. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support a high level of biodiversity.
The country has abundant natural resources like oil and natural gas, tin and gold. Agriculture produces rice, palm oil, coffee, medicinal plants and rubber. Indonesia's major trading partners are China, United States, Japan and India. History of the Indonesian archipelago has been influenced by foreign powers drawn to its natural resources, it has been an important region for trade since at least the 7th century, when Srivijaya and later Majapahit traded with entities from mainland China and the Indian subcontinent. Local rulers absorbed foreign cultural and political models from the early centuries and Hindu and Buddhist kingdoms flourished. Muslim traders and Sufi scholars brought Islam, while European powers brought Christianity and fought one another to monopolise trade in the Spice Islands of Maluku during the Age of Discovery. Although sometimes interrupted by the Portuguese and British, the Dutch were the foremost European power for much of its 350-year presence in the archipelago. In early 20th century, the concept of "Indonesia" as a nation state emerged, independence movements began to take shape.
During the decolonisation of Asia after World War II, Indonesia achieved independence in 1949 following an armed and diplomatic conflict with the Netherlands. Indonesia consists of hundreds of distinct native ethnic and linguistic groups, with the largest—and politically dominant—ethnic group being the Javanese. A shared identity has developed, defined by a national language, ethnic diversity, religious pluralism within a Muslim-majority population, a history of colonialism and rebellion against it. Indonesia's national motto, "Bhinneka Tunggal Ika", articulates the diversity that shapes the country. Indonesia's economy is the world's 16th largest by nominal GDP and the 7th largest by GDP at PPP. Indonesia is a member of several multilateral organisations, including the UN, WTO, IMF and G20, it is a founding member of Non-Aligned Movement, Association of Southeast Asian Nations, Asia-Pacific Economic Cooperation, East Asia Summit, Asian Infrastructure Investment Bank and Organisation of Islamic Cooperation.
The name Indonesia derives from the Greek name of the Indos and the word nesos, meaning "Indian islands". The name dates to the 18th century, far predating the formation of independent Indonesia. In 1850, George Windsor Earl, an English ethnologist, proposed the terms Indunesians—and, his preference, Malayunesians—for the inhabitants of the "Indian Archipelago or Malayan Archipelago". In the same publication, one of his students, James Richardson Logan, used Indonesia as a synonym for Indian Archipelago. However, Dutch academics writing in East Indies publications were reluctant to use Indonesia. After 1900, Indonesia became more common in academic circles outside the Netherlands, native nationalist groups adopted it for political expression. Adolf Bastian, of the University of Berlin, popularised the name through his book Indonesien oder die Inseln des Malayischen Archipels, 1884–1894; the first native scholar to use the name was Ki Hajar Dewantara, when in 1913 he established a press bureau in the Netherlands, Indonesisch Pers-bureau.
Fossils and the remains of tools show that the Indonesian archipelago was inhabited by Homo erectus, known as "Java Man", between 1.5 million years ago and 35,000 years ago. Homo sapiens reached the region around 45,000 years ago. Austronesian peoples, who form the majority of the modern population, migrated to Southeast Asia from what is now Taiwan, they arrived around 4,000 years ago, as they spread through the archipelago, confined the indigenous Melanesians to the far eastern regions. Ideal agricultural conditions and the mastering of wet-field rice cultivation as early as the 8th century BCE allowed villages and small kingdoms to flourish by the first century CE; the archipelago's strategic sea-lane position fostered inter-island and international trade, including links with Indian kingdoms and Chinese dynasties, which were established several centuries BCE. Trade has since fundamentally shaped Indonesian history. From the 7th century CE, the powerful Srivijaya naval kingdom flourished as a result of trade and the influences of Hinduism and Buddhism that were imported with it.
Between the 8th and 10th century CE, the agricultural Buddhist Saile
Queensland is the second-largest and third-most populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south respectively. To the east, Queensland is bordered by the Coral Pacific Ocean. To its north is the Torres Strait, with Papua New Guinea located less than 200 km across it from the mainland; the state is the world's sixth-largest sub-national entity, with an area of 1,852,642 square kilometres. As of 15 May 2018, Queensland has a population of 5,000,000, concentrated along the coast and in the state's South East; the capital and largest city in the state is Australia's third-largest city. Referred to as the "Sunshine State", Queensland is home to 10 of Australia's 30 largest cities and is the nation's third-largest economy. Tourism in the state, fuelled by its warm tropical climate, is a major industry. Queensland was first inhabited by Torres Strait Islanders.
The first European to land in Queensland was Dutch navigator Willem Janszoon in 1606, who explored the west coast of the Cape York Peninsula near present-day Weipa. In 1770, Lieutenant James Cook claimed the east coast of Australia for the Kingdom of Great Britain; the colony of New South Wales was founded in 1788 by Governor Arthur Phillip at Sydney. Queensland was explored in subsequent decades until the establishment of a penal colony at Brisbane in 1824 by John Oxley. Penal transportation ceased in 1839 and free settlement was allowed from 1842; the state was named in honour of Queen Victoria, who on 6 June 1859 signed Letters Patent separating the colony from New South Wales. Queensland Day is celebrated annually statewide on 6 June. Queensland was one of the six colonies which became the founding states of Australia with federation on 1 January 1901; the history of Queensland spans thousands of years, encompassing both a lengthy indigenous presence, as well as the eventful times of post-European settlement.
The north-eastern Australian region was explored by Dutch and French navigators before being encountered by Lieutenant James Cook in 1770. The state has witnessed frontier warfare between European settlers and Indigenous inhabitants, as well as the exploitation of cheap Kanaka labour sourced from the South Pacific through a form of forced recruitment known at the time as "blackbirding"; the Australian Labor Party has its origin as a formal organisation in Queensland and the town of Barcaldine is the symbolic birthplace of the party. June 2009 marked the 150th anniversary of its creation as a separate colony from New South Wales. A rare record of early settler life in north Queensland can be seen in a set of ten photographic glass plates taken in the 1860s by Richard Daintree, in the collection of the National Museum of Australia; the Aboriginal occupation of Queensland is thought to predate 50,000 BC via boat or land bridge across Torres Strait, became divided into over 90 different language groups.
During the last ice age Queensland's landscape became more arid and desolate, making food and other supplies scarce. This led to the world's first seed-grinding technology. Warming again made the land hospitable, which brought high rainfall along the eastern coast, stimulating the growth of the state's tropical rainforests. In February 1606, Dutch navigator Willem Janszoon landed near the site of what is now Weipa, on the western shore of Cape York; this was the first recorded landing of a European in Australia, it marked the first reported contact between European and Aboriginal Australian people. The region was explored by French and Spanish explorers prior to the arrival of Lieutenant James Cook in 1770. Cook claimed the east coast under instruction from King George III of the United Kingdom on 22 August 1770 at Possession Island, naming Eastern Australia, including Queensland,'New South Wales'; the Aboriginal population declined after a smallpox epidemic during the late 18th century. In 1823, John Oxley, a British explorer, sailed north from what is now Sydney to scout possible penal colony sites in Gladstone and Moreton Bay.
At Moreton Bay, he found the Brisbane River. He established a settlement at what is now Redcliffe; the settlement known as Edenglassie, was transferred to the current location of the Brisbane city centre. Edmund Lockyer discovered outcrops of coal along the banks of the upper Brisbane River in 1825. In 1839 transportation of convicts was ceased, culminating in the closure of the Brisbane penal settlement. In 1842 free settlement was permitted. In 1847, the Port of Maryborough was opened as a wool port; the first free immigrant ship to arrive in Moreton Bay was the Artemisia, in 1848. In 1857, Queensland's first lighthouse was built at Cape Moreton. A war, sometimes called a "war of extermination", erupted between Aborigines and settlers in colonial Queensland; the Frontier War was notable for being the most bloody in Australia due to Queensland's larger pre-contact indigenous population when compared to the other Australian colonies. About 1,500 European settlers and their alli
A relish is a cooked and pickled product made of chopped vegetables, fruits or herbs, is a food item used as a condiment, in particular to enhance a staple. Examples are chutneys and the North American relish, a pickled cucumber jam eaten with hot dogs or hamburgers. In North America, the word "relish" is used to describe a single variety of finely-chopped pickled cucumber relish, such as pickle and sweet relishes; such relishes are used as a condiment, pickle relish is an important ingredient in many varieties of the U. S. version of tartar sauce. Relish consists of discernible vegetable or fruit pieces in a sauce, although the sauce is subordinate in character to the vegetable or fruit pieces. Herbs may be used, some relishes, such as chermoula, are prepared using herbs and spices. Relish can consist of a combination of these; these fruits or vegetables might be coarsely or finely chopped, the texture of relish can vary depending on the style of slicing used for its solid ingredients, but a relish is not as smooth as a sauce-type condiment, such as ketchup.
The overall taste sensation might be sweet, mild or hot, but it has a strong flavor that complements or adds to the primary food item with which it is served. The English word "chutney" originated in India; this is a list of notable relishes. In the United States, the most common commercially available relishes are made from pickled cucumbers and are known in the food trade as pickle relishes. Pickle relish is one of the most used spreads in the U. S. Two variants of this are hot dog relish. Another available commercial relish in the U. S. is corn relish. Heinz and Claussen are well known in the U. S. as producers of pickled cucumbers and pickle relishes. Chicago-style relish is a sweet pickle relish, a standard ingredient on the Chicago-style hot dog.

The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. The various types of sugar are derived from different sources. Simple sugars are called monosaccharides and include glucose and galactose. "Table sugar" or "granulated sugar" refers to a disaccharide of glucose and fructose. In the body, sucrose is hydrolysed into glucose. Sugars are found in the tissues of most plants, but sucrose is concentrated in sugarcane and sugar beet, making them ideal for efficient commercial extraction to make refined sugar. Sugarcane originated in tropical Indian subcontinent and Southeast Asia, is known of from before 6,000 BP, sugar beet was first described in writing by Olivier de Serres and originated in southwestern and Southeast Europe along the Atlantic coasts and the Mediterranean Sea, in North Africa, Macaronesia, to Western Asia. In 2016, the combined world production of those two crops was about two billion tonnes. Other disaccharides include lactose. Longer chains of sugar molecules are called polysaccharides.
Some other chemical substances, such as glycerol and sugar alcohols, may have a sweet taste, but are not classified as sugar. Sucrose is used in prepared foods, is sometimes added to commercially available beverages, may be used by people as a sweetener for foods and beverages; the average person consumes about 24 kilograms of sugar each year, or 33.1 kilograms in developed countries, equivalent to over 260 food calories per day. As sugar consumption grew in the latter part of the 20th century, researchers began to examine whether a diet high in sugar refined sugar, was damaging to human health. Excessive consumption of sugar has been implicated in the onset of obesity, cardiovascular disease and tooth decay. Numerous studies have tried to clarify those implications, but with varying results because of the difficulty of finding populations for use as controls that consume little or no sugar. In 2015, the World Health Organization recommended that adults and children reduce their intake of free sugars to less than 10%, encouraged a reduction to below 5%, of their total energy intake.
The etymology reflects the spread of the commodity. From Sanskrit शर्करा, meaning "ground or candied sugar," "grit, gravel", came Persian shakar, whence Arabic سكر, whence Medieval Latin succarum, whence 12th-century French sucre, whence the English word sugar. Italian zucchero, Spanish azúcar, Portuguese açúcar came directly from Arabic, the Spanish and Portuguese words retaining the Arabic definite article; the earliest Greek word attested is σάκχαρις. The English word jaggery, a coarse brown sugar made from date palm sap or sugarcane juice, has a similar etymological origin: Portuguese jágara from the Malayalam ചക്കരാ, itself from the Sanskrit शर्करा. Sugar has been produced in the Indian subcontinent since ancient times and its cultivation spread from there into modern-day Afghanistan through the Khyber Pass, it was not plentiful or cheap in early times, in most parts of the world, honey was more used for sweetening. People chewed raw sugarcane to extract its sweetness. Sugarcane was a native of Southeast Asia.
Different species seem to have originated from different locations with Saccharum barberi originating in India and S. edule and S. officinarum coming from New Guinea. One of the earliest historical references to sugarcane is in Chinese manuscripts dating to 8th century BCE, which state that the use of sugarcane originated in India. In the tradition of Indian medicine, the sugarcane is known by the name Ikṣu and the sugarcane juice is known as Phāṇita, its varieties and characterics are defined in nighaṇṭus such as the Bhāvaprakāśa. Sugar remained unimportant until the Indians discovered methods of turning sugarcane juice into granulated crystals that were easier to store and to transport. Crystallized sugar was discovered by the time of the Imperial Guptas, around the 5th century CE. In the local Indian language, these crystals were called khanda, the source of the word candy. Indian sailors, who carried clarified butter and sugar as supplies, introduced knowledge of sugar along the various trade routes they travelled.
Traveling Buddhist monks took sugar crystallization methods to China. During the reign of Harsha in North India, Indian envoys in Tang China taught methods of cultivating sugarcane after Emperor Taizong of Tang made known his interest in sugar. China established its first sugarcane plantations in the seventh century. Chinese documents confirm at least two missions to India, initiated in 647 CE, to obtain technology for sugar refining. In the Indian subcontinent, the Middle East and China, sugar became a staple of cooking and desserts. Nearchus, admiral of Alexander of Macedonia, knew of sugar during the year 325 B. C. because of his participation in the campaign of India led by Alexander. The Greek physician Pedanius Dioscorides in the 1st century CE described sugar in his medical treatise De Materia Medica, Pliny the Elder, a 1st-century CE Roman, described sugar in his Natural History: "Sugar is made in Arabia as well, but Indian sugar is better, it is a kind of honey found in cane, white as gum, it crunches between the teeth.
It comes in lumps the size of a hazelnut. Sugar is used only for medical purposes." Crusaders brought sugar back to Europe after their campaigns in the Hol
The Indian subcontinent known as the Asian subcontinent and Indo subcontinent, is a southern region and peninsula of Asia situated on the Indian Plate and projecting southwards into the Indian Ocean from the Himalayas. Geologically, the Indian subcontinent is related to the land mass that rifted from Gondwana and merged with the Eurasian plate nearly 55 million years ago. Geographically, it is the peninsular region in south-central Asia delineated by the Himalayas in the north, the Hindu Kush in the west, the Arakanese in the east. Politically, the Indian subcontinent includes Bangladesh, India, Nepal and Sri Lanka. Sometimes, the geographical term'Indian subcontinent' is used interchangeably with'South Asia', although that last term is used as a political term and is used to include Afghanistan. Which countries should be included in either of these remains the subject of debate. According to Oxford English Dictionary, the term "subcontinent" signifies a "subdivision of a continent which has a distinct geographical, political, or cultural identity" and a "large land mass somewhat smaller than a continent".
It is first attested in 1845 to refer to the North and South Americas, before they were regarded as separate continents. Its use to refer to the Indian subcontinent is seen from the early twentieth century, it was convenient for referring to the region comprising both British India and the princely states under British Paramountcy. The term Indian subcontinent has a geological significance. Similar to various continents, it was a part of the supercontinent of Gondwana. A series of tectonic splits caused formation of various basins, each drifting in various directions; the geological region called "Greater India" once included Madagascar, Seychelles and Austrolasia along with the Indian subcontinent basin. As a geological term, Indian subcontinent has meant that region formed from the collision of the Indian basin with Eurasia nearly 55 million years ago, towards the end of Paleocene; the geographical region has simply been known as "India". Other related terms are South Asia, and the terms "Indian subcontinent" and "South Asia" are sometimes used interchangeably.
There is no globally accepted definition on which countries are a part of South Asia or the Indian subcontinent. The less common term "South Asian subcontinent" has seen occasional use since the 1970s. Geologically, the Indian subcontinent was first a part of so-called "Greater India", a region of Gondwana that drifted away from East Africa about 160 million years ago, around the Middle Jurassic period; the region experienced high volcanic activity and plate subdivisions, creating Madagascar, Antarctica and the Indian subcontinent basin. The Indian subcontinent drifted northeastwards, colliding with the Eurasian plate nearly 55 million years ago, towards the end of Paleocene; this geological region includes Bangladesh, India, Nepal and Sri Lanka. The zone where the Eurasian and Indian subcontinent plates meet remains one of the geologically active areas, prone to major earthquakes; the English term "subcontinent" continues to refer to the Indian subcontinent. Physiographically, it is a peninsular region in south-central Asia delineated by the Himalayas in the north, the Hindu Kush in the west, the Arakanese in the east.
It extends southward into the Indian Ocean with the Arabian Sea to the southwest and the Bay of Bengal to the southeast. Most of this region rests on the Indian Plate and is isolated from the rest of Asia by large mountain barriers. Using the more expansive definition – counting India, Bangladesh, Sri Lanka, Nepal and Maldives as the constituent countries – the Indian subcontinent covers about 4.4 million km2, 10% of the Asian continent or 3.3% of the world's land surface area. Overall, it is home to a vast array of peoples; the Indian subcontinent is a natural physical landmass in South Asia, geologically the dry-land portion of the Indian Plate, isolated from the rest of Eurasia. Given the difficulty of passage through the Himalayas, the sociocultural and political interaction of the Indian subcontinent has been through the valleys of Afghanistan in its northwest, the valleys of Manipur in its east, by maritime routes. More difficult but important interaction has occurred through passages pioneered by the Tibetans.
These routes and interactions have led to the spread of Buddhism out of the Indian subcontinent into other parts of Asia. And the Islamic expansion arrived into the Indian subcontinent in two ways, through Afghanistan on land and to Indian coast through the maritime routes on the Arabian Sea. Whether called the Indian subcontinent or South Asia, the definition of the geographical extent of this region varies. Geopolitically, it had formed the whole territory of Greater India. In terms of modern geopolitical boundaries, the Indian subcontinent comprises the Republic of India, Bangladesh, Bhutan, besides, by convention, the island nation of Sri Lanka and other islands of the Indian Ocean, such as the Maldives; the term "Indian continent" is first introduced in the early 20th century, when most of the territory was part of British India. The Hindu Kush, centered on eastern Afghanistan, is the boundary connecting the Indian subcontinent with Central Asia to the northwest, the Persian Plateau to the west.
The socio-religious history of Afghanistan are related to the Turkish-influenced Central Asia and no
Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue and can serve as a fuel source; as a fuel, proteins provide as much energy density as carbohydrates: 4 kcal per gram. The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. Proteins are polymer chains made of amino acids linked together by peptide bonds. During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions; this is crucial for the absorption of the essential amino acids that cannot be biosynthesized by the body. There are nine essential amino acids which humans must obtain from their diet in order to prevent protein-energy malnutrition and resulting death, they are phenylalanine, threonine, methionine, isoleucine and histidine. There has been debate as to whether there are 9 essential amino acids; the consensus seems to lean towards 9. There are five amino acids.
These five are alanine, aspartic acid, glutamic acid and serine. There are six conditionally essential amino acids whose synthesis can be limited under special pathophysiological conditions, such as prematurity in the infant or individuals in severe catabolic distress; these six are arginine, glycine, glutamine and tyrosine. Dietary sources of protein include both animals and plants: meats, dairy products and eggs, as well as grains and nuts. Vegans can get enough essential amino acids by eating plant proteins. Protein is a nutrient needed by the human body for maintenance. Aside from water, proteins are the most abundant kind of molecules in the body. Protein can be found in all cells of the body and is the major structural component of all cells in the body muscle; this includes body organs and skin. Proteins are used in membranes, such as glycoproteins; when broken down into amino acids, they are used as precursors to nucleic acid, co-enzymes, immune response, cellular repair, other molecules essential for life.
Additionally, protein is needed to form blood cells. Protein can be found in a wide range of food; the best combination of protein sources depends on the region of the world, cost, amino acid types and nutrition balance, as well as acquired tastes. Some foods are high in certain amino acids, but their digestibility and the anti-nutritional factors present in these foods make them of limited value in human nutrition. Therefore, one must consider digestibility and secondary nutrition profile such as calories, cholesterol and essential mineral density of the protein source. On a worldwide basis, plant protein foods contribute over 60 percent of the per capita supply of protein, on average. In North America, animal-derived foods contribute about 70 percent of protein sources. Meat, products from milk, eggs and fish are sources of complete protein. Whole grains and cereals are another source of proteins. However, these tend to be limiting in the amino acid lysine or threonine, which are available in other vegetarian sources and meats.
Examples of food staples and cereal sources of protein, each with a concentration greater than 7.0%, are buckwheat, rye, maize, wheat, sorghum and quinoa. Vegetarian sources of proteins include legumes, nuts and fruits. Legumes, some of which are called pulses in certain parts of the world, have higher concentrations of amino acids and are more complete sources of protein than whole grains and cereals. Examples of vegetarian foods with protein concentrations greater than 7 percent include soybeans, kidney beans, white beans, mung beans, cowpeas, lima beans, pigeon peas, wing beans, Brazil nuts, pecans, cotton seeds, pumpkin seeds, hemp seeds, sesame seeds, sunflower seeds. Food staples that are poor sources of protein include roots and tubers such as yams and sweet potato. Plantains, another major staple, are a poor source of essential amino acids. Fruits, while rich in other essential nutrients, are another poor source of amino acids; the protein content in roots and fruits is between 0 and 2 percent.
Food staples with low protein content must be complemented with foods with complete, quality protein content for a healthy life in children for proper development. A good source of protein is a combination of various foods, because different foods are rich in different amino acids. A good source of dietary protein meets two requirements: The requirement for the nutritionally indispensable amino acids under all conditions and for conditionally indispensable amino acids under specific physiological and pathological conditions The requirement for nonspecific nitrogen for the synthesis of the nutritionally dispensable amino acids and other physiologically important nitrogen-containing compounds such as nucleic acids and porphyrins. Healthy people eating a balanced diet need protein supplements; the table below presents the most important food groups as protein sources, from a worldwide perspective. It lists their respective performance as source of the limiting amino acids, in milligrams of limiting amino acid per gram of total protein in the food source.
The table reiterates the need for a balanced mix of
