Marion Gordon "Pat" Robertson (March 22, 1930 – June 8, 2023) was an American media mogul, religious broadcaster, political commentator, presidential candidate, and Southern Baptist minister. Robertson advocated a conservative Christian ideology and was known for his involvement in Republican Party politics. He was associated with the Charismatic movement within Protestant evangelicalism. He served as head of Regent University and of the Christian Broadcasting Network (CBN).

Robertson's career spanned over five decades, and was the founder of several organizations, including CBN, Regent University, Operation Blessing International Relief and Development Corporation, the International Family Entertainment Inc. (ABC Family Channel/Freeform), the American Center for Law & Justice (ACLJ), the Founders Inn and Conference Center, and the Christian Coalition. Robertson was also a best-selling author and the host of The 700 Club, a Christian News and TV program broadcast live weekdays on Freeform (formerly ABC Family) from CBN studios, as well as on channels throughout the United States, and on CBN network affiliates worldwide. Robertson retired from The 700 Club in October 2021.

The son of U.S. Senator A. Willis Robertson, Robertson was a Southern Baptist and was active as an ordained minister with that denomination for many years, but held to a charismatic theology not traditionally common among Southern Baptists. He unsuccessfully campaigned to become the Republican nominee in the 1988 presidential election. As a result of his seeking political office, he never again served in an official role for any church. Robertson remained a controversial figure. While he became a recognized and influential public voice for conservative Christianity in the U.S. and around the world, his opposition to various progressive causes, including LGBT rights, feminism, and the right to abortion, was frequently criticized.

Early life
Marion Gordon Robertson was born on March 22, 1930, in Lexington, Virginia, into a prominent political family, the younger of two sons. His parents were Absalom Willis Robertson (1887–1971), a conservative Democratic Senator, and Gladys Churchill (née Willis; 1897–1968), a housewife and a musician. At a young age, Robertson was nicknamed 'Pat' by his six-year-old brother, Willis Robertson, Jr., who enjoyed patting him on the cheeks when he was a baby while saying "pat, pat, pat". Later, Robertson thought about which first name he would like people to use. He considered "Marion" to be effeminate, and "M. Gordon" to be affected, so he opted for his childhood nickname "Pat".

When he was eleven, Robertson was enrolled in the preparatory McDonogh School outside Baltimore, Maryland. From 1940 until 1946 he attended The McCallie School in Chattanooga, Tennessee, where he graduated with honors. He gained admission to Washington and Lee University, where he earned a B.A. in History, graduating magna cum laude. He was also a member of Phi Beta Kappa, the nation's most prestigious academic honor society. He joined Sigma Alpha Epsilon fraternity. Robertson said, "Although I worked hard at my studies, my real major centered around lovely young ladies who attended the nearby girls schools."

In 1948, the draft was reinstated and Robertson was given the option of joining the U.S. Marine Corps or being drafted into the U.S. Army; he opted for the former. Robertson described his military service as follows: "We did long, grueling marches to toughen the men, plus refresher training in firearms and bayonet combat." In the same year, he transferred to Korea, "I ended up at the headquarters command of the First Marine Division," says Robertson. "The Division was in combat in the hot and dusty, then bitterly cold portion of North Korea just above the 38th Parallel later identified as the 'Punchbowl' and 'Heartbreak Ridge'." For Robertson's service in the Korean War, he was awarded three Battle Stars.

In 1986, former Republican Congressman Paul "Pete" McCloskey, Jr., who served with Robertson in Camp Pendleton, wrote a public letter challenging Robertson's record in the military. Robertson filed a libel suit against McCloskey but he dropped the case in 1988 in order to devote "his full time and energies toward the successful attainment of the Republican nomination for the president of the United States."

Robertson was promoted to First Lieutenant in 1952 upon his return to the United States. He then went on to receive a law degree from Yale Law School in 1955, near the top of his class. However, he failed his first and only attempt at the New York bar exam necessary for admission to the New York State Bar Association, which did not deter Robertson because he never intended to practice law anyway. Shortly thereafter he underwent a religious conversion and decided against pursuing a career in business. Instead, Robertson attended The Biblical Seminary in New York, where he received a Master of Divinity degree in 1959. He became a born again Christian while having dinner at a restaurant in Philadelphia with author and World War II veteran, Cornelius Vanderbreggen. After his conversion, Robertson left the corporate world and went into ministry.

Christian Broadcasting Network

In 1956, Robertson met Dutch missionary Cornelius Vanderbreggen, who impressed Robertson both with his lifestyle and his message. Vanderbreggen quoted Proverbs (3:5, 6), "Trust in the Lord with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge Him, and He shall direct thy paths", which Robertson considered being the "guiding principle" of his life. He was ordained as a minister of the Southern Baptist Convention in 1961.

In 1960, Robertson established the Christian Broadcasting Network in Virginia Beach, Virginia by buying the license of a defunct UHF station in nearby Portsmouth. The station, with the call sign WYAH-TV, first broadcast on October 1, 1961. The network became known for producing the long-running TV series The 700 Club, starting in 1966, which Robertson served as a long time co-host.  On April 29, 1977, CBN launched a religious cable network, the CBN Satellite Service, which eventually became The Family Channel. It was the first satellite television channel in America to connect to cable systems across the country. The venture became extremely lucrative, so Robertson spun off The Family Channel as a commercial entity that was sold to News Corporation for $1.9 billion in 1997.

In 1994, he endorsed the document "Evangelicals and Catholics Together". Robertson announced his retirement at the age of 91 from The 700 Club in October 2021, on the sixtieth anniversary of the first telecast on October 1, 1961 of what eventually became CBN.

Regent University

Robertson founded CBN University, a private Christian university, in 1977 on CBN's Virginia Beach campus. Since its founding, the university has established eight academic schools and offers associate, bachelor's, master's, and doctoral degrees in over 150 areas of study. It was renamed Regent University in 1990. According to the school's catalog, "a regent is one who represents Christ, our Sovereign, in whatever sphere of life he or she may be called to serve Him."

With more than 11,000 current students, Regent University has ranked the #1 Best Online Bachelor's Program in Virginia for ten years in a row by U.S. News & World Report 2022, as well as 2023 Best Graduate Schools-Law, Best Graduate Schools – Social Sciences and Humanities Doctoral Programs – Psychology, 2023 Best Graduate Schools – Public Affairs, and 2023 Best Education Schools by U.S. News & World Report. Robertson served as its chancellor and CEO.

Robertson was also founder and president of the American Center for Law & Justice, a public interest law firm headquartered in Washington, D.C. associated with Regent University School of Law in Virginia Beach, Virginia, which defends constitutional freedoms and conservative Christian ideals. Critics have characterized Robertson as an advocate of dominionism.

Operation Blessing

Robertson's Operation Blessing organization sent medical teams to developing countries to help people who had no access to medical care. In 1994, in the aftermath of the Rwandan genocide, Robertson solicited donations to provide medical supplies to refugees in neighboring Zaire (present-day Congo), where Robertson also had exploratory diamond mining operations. According to a 1999 article in The Virginian-Pilot, two Operation Blessing pilots who were interviewed alleged that the organization's planes were used to haul diamond-mining equipment to Robertson's mines in Zaire. Robertson denied the pilots' accounts.

In its 2021 ranking of "100 Largest Charities," Forbes ranked Operation Blessing/CBN at #44, with an efficiency rating of over 90%.

Other ventures
Robertson was the founder and chairman of The Christian Broadcasting Network (CBN) Inc., and founder of International Family Entertainment Inc., Regent University, Operation Blessing International Relief and Development Corporation, American Center for Law and Justice, The Flying Hospital, Inc., and several other organizations and broadcast entities. Robertson was the founder and co-chairman of International Family Entertainment Inc. (IFE).

Formed in 1990, IFE produced and distributed family entertainment and information programming worldwide. IFE's principal business was The Family Channel, a satellite delivered cable-television network with 63 million U.S. subscribers. IFE, a publicly held company listed on the New York Stock Exchange, was sold in 1997 to Fox Kids Worldwide, Inc. for $1.9billion, whereupon it was renamed Fox Family Channel. Disney acquired FFC in 2001 and its name was changed again, to ABC Family. The network was renamed to Freeform on January 12, 2016, though Robertson's sale of the channel continues to require Freeform to carry four hours of CBN/700 Club programming per weekday, along with CBN's yearly telethon.

Robertson was a global businessman with media holdings in Asia, the United Kingdom, and Africa. He struck a deal with Pittsburgh, Pennsylvania-based General Nutrition Center to produce and market a weight-loss shake he created and promoted on The 700 Club.

In 1999, Robertson entered into a joint venture with the Bank of Scotland to provide financial services in the United States. However, the venture fell through after progressive activists protested over Robertson's Biblical views on an array of issues.

While some have estimated his wealth to have been between$200million and $1 billion, Robertson claimed that these estimates were not based on any facts and were incorrect.

A June 2, 1999 article in The Virginian-Pilot alleged that Robertson had business dealings with Liberian president Charles Taylor, with whom Robertson, according to the article, negotiated a multimillion- dollar contract for gold mining operations in Liberia. Robertson denied any business dealings with Taylor, and he also denied ever speaking to President George W. Bush about Taylor's alleged activities. On February 4, 2010, at his war crimes trial in the Hague, Taylor testified that Robertson was his main political ally in the U.S., while Robertson has denied ever meeting or speaking to Charles Taylor.

Beginning in the latter part of the 1990s, Robertson raced thoroughbred horses under the nom de course Tega Farm. His gelding named Tappat won the 1999 Walter Haight Handicap at Laurel Park and the 2000 Pennsylvania Governor's Cup Handicap at Penn National Race Course. Following this success, Robertson paid $520,000 for a colt he named Mr. Pat. Trained by John Kimmel, Mr. Pat was not a successful runner. He was nominated for, but did not run in, the 2000 Kentucky Derby.

Political service and activism

Robertson was a past president of the Council for National Policy. In 1982, he served on the Victims of Crime Task Force for U.S. President Ronald Reagan. In Virginia, he served on the Board of the Virginia Economic Development Partnership and on the Governor's Council of Economic Advisors. After his unsuccessful presidential campaign, Robertson started the Christian Coalition, a 1.7-million-member Christian right organization that campaigned mostly for conservative candidates. Billy McCormack, a Southern Baptist pastor in Shreveport, Louisiana, served as one of the four directors of the coalition as well as its vice president. The coalition was sued by the Federal Election Commission "for coordinating its activities with Republican candidates for office in 1990, 1992 and 1994 and failing to report its expenditures," yet the complaint was dismissed by a federal judge. In March 1986, he told Israeli Foreign Affairs that South Africa was a major contributor to the Reagan administration's efforts to help the anti-Sandinista forces.

In 1994, the Coalition was fined for "improperly [aiding] then Representative Newt Gingrich (R-GA) and Oliver North, who was then the Republican Senate nominee in Virginia."

Robertson was a governing member of the Council for National Policy (CNP) and served on its Board of Governors in 1982, was the President of its Executive Committee from 1985 to 1986, and a member in 1984, 1988, and 1998.

On November 7, 2007, Robertson announced that he was endorsing Rudy Giuliani to be the Republican nominee in the 2008 Presidential election. Some social conservatives criticized Robertson's endorsement of Giuliani, a pro-choice candidate who supported gay rights.

While usually associated with the political right, Robertson endorsed environmental causes. He appeared in a commercial with Al Sharpton, joking about this, and urging people to join the We Can Solve It campaign against global warming.

In January 2009, on a broadcast of The 700 Club, Robertson stated that he was "adamantly opposed" to the division of Jerusalem between Israel and the Palestinians. He also stated that Armageddon was "not going to be fought at Megiddo" but would be the "battle of Jerusalem," when "the forces of all nations come together and try to take Jerusalem away from the Jews. Jews are not going to give up Jerusalemthey shouldn'tand the rest of the world is going to insist they give it up." Robertson added that Jerusalem is a "spiritual symbol that must not be given away" because "Jesus Christ the Messiah will come down to the part of Jerusalem that the Arabs want," and this would be "not good."

Robertson repeatedly called for the legalization of cannabis, saying that it should be treated in a manner analogous to the regulation of alcoholic beverages and tobacco. Robertson stated that "I just think it's shocking how many of these young people wind up in prison and they get turned into hard-core criminals because they had a possession of a very small amount of controlled substance. The whole thing is crazy." In 2014, he turned against the legalization of cannabis.

1988 presidential bid

In September 1986, Robertson announced his intention to seek the Republican nomination for President of the United States. Robertson said he would pursue the nomination only if three million people signed up to volunteer for his campaign by September 1987. Three million responded, and by the time Robertson announced he would be running in September 1987, he also had raised millions of dollars for his campaign fund. He surrendered his ministerial credentials and turned leadership of CBN over to his son, Tim.

Robertson ran on a standard conservative platform, and as a candidate he embraced the same policies as Ronald Reagan: lower taxes, a balanced budget, and a strong defense.

Robertson's campaign achieved a strong second-place finish in the Iowa caucuses, ahead of Bush. He did poorly in the subsequent New Hampshire primary, however, and was unable to be competitive once the multiple-state primaries began. Robertson ended his campaign before the primaries were finished. His best finish was in Washington, winning the majority of caucus delegates.

Personal life

Marriage and family
In 1954, Robertson married Adelia "Dede" Elmer a fashion model and beauty queen in the Miss Ohio State contest, who was studying for her masters in nursing at Yale University. She had also been a nursing student at Ohio State University in Columbus, Ohio. They remained married until her death in 2022, and had four children, among them Gordon P. Robertson.

Illness and death
On August 11, 2017, Robertson was hospitalized after sustaining minor injuries in a fall from a horseback riding incident.

On February 2, 2018, Robertson suffered an embolic stroke at his home in Virginia Beach. A member of his family noticed his symptoms and alerted emergency medical personnel. He was then taken to the nearest stroke center where he was administered the clot-busting drug tPA. Robertson was responsive, awake, and moving all of his limbs about eighty minutes after his stroke began. He was discharged two days later and recovered at home. Following this incident, Robertson and his family thanked the paramedics and medical staff for their "extraordinary care and rapid response." They also urged people to learn about stroke, its symptoms and treatments. Robertson resumed his hosting duties on The 700 Club on February 12.

In June 2019, Robertson was absent from The 700 Club for several days after he broke three ribs in a fall. Upon his return, described the experience as very painful but said "Us old guys are tough, and we try to stay in there and keep on going." He then thanked viewers for their prayers.

On June 8, 2023, Robertson died at his home in Virginia Beach, Virginia, at the age of 93.

Controversies

As a commentator and minister, Robertson's statements frequently generated controversy.

Robertson's service as a minister included the belief in the healing power of God. He cautioned believers that some Protestant denominations may harbor the spirit of the Antichrist; prayed to deflect hurricanes; denounced Hinduism as "demonic" and Islam as "Satanic".

Robertson denounced left-wing views of feminism, activism regarding homosexuality, abortion, and liberal college professors. Critics claim Robertson had business dealings in Africa with former president of Liberia and convicted war criminal Charles Taylor, and former Zaire president Mobutu Sese Seko, both of whom had been globally denounced for claims of human rights violations. Robertson was criticized worldwide for his call for Hugo Chávez's assassination, and for his remarks concerning Ariel Sharon's ill health as an act of God.

During the week of September 11, 2001, Robertson interviewed Jerry Falwell, who expressed his own opinion that "the ACLU has to take a lot of blame for this" in addition to "the pagans, and the abortionists, and the feminists, and the gays, and the lesbians [who have] helped [the terror attacks of September 11th] happen." Robertson replied, "I totally concur". Both evangelists were seriously criticized by President George W. Bush for their comments, for which Falwell later issued an apology.

Less than two weeks after Hurricane Katrina killed 1,836 people, Robertson implied on the September 12, 2005 broadcast of The 700 Club that the storm was God's punishment in response to America's abortion policy. He suggested that the September 11 attacks and the disaster in New Orleans "could[...] be connected in some way".

In 2009, Robertson said that Islam is "a violent political system bent on the overthrow of the governments of the world and world domination". He went on to elaborate that "you're dealing with not a religion, you're dealing with a political system, and I think we should treat it as such, and treat its adherents as such as we would members of the communist party, members of some fascist group".

Robertson's response to the 2010 Haiti earthquake also sparked worldwide condemnation. Robertson claimed that Haiti's founders had sworn a "pact to the Devil" in order to liberate themselves from the French slave owners and indirectly attributed the earthquake to the consequences of the Haitian people being "cursed" for doing so. CBN later issued a statement saying that Robertson's comments "were based on the widely-discussed 1791 slave rebellion led by Dutty Boukman at Bois Caïman, where the slaves allegedly made a famous pact with the devil in exchange for victory over the French". Various figures in mainline and evangelical Christianity have on occasion disavowed some of Robertson's remarks.

In March 2015, Robertson compared Buddhism to a disease on The 700 Club. The American Center for Law and Justice (ACLJ), a conservative Christian watchdog group Robertson founded to promote Christian prayer in public schools, called for a multi-pronged attack on mindfulness programs because "they appear to be similar to Buddhist religious practices. Proponents of secular mindfulness say mindfulness is not a Buddhist practice; it is a contemplative practice used in religious traditions around the world by many different names."

Publications
Robertson's book The New World Order (1991) became a New York Times best seller. A review by Ephraim Radner, an Episcopalian professor of theology, stated:
 In October 2003, Robertson was interviewed by author Joel Mowbray about his book Dangerous Diplomacy, a book critical of the United States Department of State. Robertson said that Americans could change American diplomacy by ridding America of a large part of the State Department.

Pat Robertson


A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi, and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures, such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted to smaller molecules in the process of releasing energy, such as for carbohydrates, lipids, proteins, and fermentation products (ethanol or vinegar), leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host.

Different types of organisms have different essential nutrients. Ascorbic acid (vitamin C) is essential, meaning it must be consumed in sufficient amounts, to humans and some other animal species, but some animals and plants are able to synthesize it. Nutrients may be organic or inorganic: organic compounds include most compounds containing carbon, while all other chemicals are inorganic. Inorganic nutrients include nutrients such as iron, selenium, and zinc, while organic nutrients include, among many others, energy-providing compounds and vitamins.

A classification used primarily to describe nutrient needs of animals divides nutrients into macronutrients and micronutrients. Consumed in relatively large amounts (grams or ounces), macronutrients (carbohydrates, fats, proteins, water) are primarily used to generate energy or to incorporate into tissues for growth and repair. Micronutrients are needed in smaller amounts (milligrams or micrograms); they have subtle biochemical and physiological roles in cellular processes, like vascular functions or nerve conduction. Inadequate amounts of essential nutrients, or diseases that interfere with absorption, result in a deficiency state that compromises growth, survival and reproduction. Consumer advisories for dietary nutrient intakes, such as the United States Dietary Reference Intake, are based on deficiency outcomes and provide macronutrient and micronutrient guides for both lower and upper limits of intake. In many countries, macronutrients and micronutrients in significant content are required by regulations to be displayed on food product labels. Nutrients in larger quantities than the body needs may have harmful effects. Edible plants also contain thousands of compounds generally called phytochemicals which have unknown effects on disease or health, including a diverse class with non-nutrient status called polyphenols, which remain poorly understood as of 2017.

Types

Macronutrients
Macronutrients are defined in several ways.
 The chemical elements humans consume in the largest quantities are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulphur, summarized as CHNOPS.
 The chemical compounds that humans consume in the largest quantities and provide bulk energy are classified as carbohydrates, proteins, and fats. Water must be also consumed in large quantities but does not provide caloric value.
 Calcium, sodium, potassium, magnesium, and chloride ions, along with phosphorus and sulfur, are listed with macronutrients because they are required in large quantities compared to micronutrients, i.e., vitamins and other minerals, the latter often described as trace or ultratrace minerals.

Macronutrients provide energy:
 Carbohydrates are compounds made up of types of sugar. Carbohydrates are classified according to their number of sugar units: monosaccharides (such as glucose and fructose), disaccharides (such as sucrose and lactose), oligosaccharides, and polysaccharides (such as starch, glycogen, and cellulose).
 Proteins are organic compounds that consist of amino acids joined by peptide bonds. Since the body cannot manufacture some of the amino acids (termed essential amino acids), the diet must supply them. Through digestion, proteins are broken down by proteases back into free amino acids.
 Fats consist of a glycerin molecule with three fatty acids attached. Fatty acid molecules contain a -COOH group attached to unbranched hydrocarbon chains connected by single bonds alone (saturated fatty acids) or by both double and single bonds (unsaturated fatty acids). Fats are needed for construction and maintenance of cell membranes, to maintain a stable body temperature, and to sustain the health of skin and hair. Because the body does not manufacture certain fatty acids (termed essential fatty acids), they must be obtained through one's diet.
 Ethanol is not an essential nutrient, but it does provide calories.The United States Department of Agriculture uses a figure of  per gram of alcohol ( per ml) for calculating food energy. For distilled spirits, a standard serving in the U.S. is , which at 40% ethanol (80 proof) would be 14 grams and 98 calories.

Micronutrients
Micronutrients  are essential dietary elements required in varying quantities throughout life to serve metabolic and physiological functions.

 Dietary minerals, such as copper and iron, are elements native to Earth, and cannot be synthesized. They are required in the diet in microgram or milligram amounts. As plants obtain minerals from the soil, dietary minerals derive directly from plants consumed or indirectly from edible animal sources.
 Vitamins are organic compounds required in microgram or milligram amounts. The importance of each dietary vitamin was first established when a disease would develop if that vitamin was absent from the diet.

Essentiality

Essential nutrients

An essential nutrient is a nutrient required for normal physiological function that cannot be synthesized in the body – either at all or in sufficient quantities – and thus must be obtained from a dietary source. Apart from water, which is universally required for the maintenance of homeostasis in mammals, essential nutrients are indispensable for various cellular metabolic processes and for the maintenance and function of tissues and organs. The nutrients considered essential for humans comprise nine amino acids, two fatty acids, thirteen vitamins, fifteen minerals and choline. In addition, there are several molecules that are considered conditionally essential nutrients since they are indispensable in certain developmental and pathological states.

Amino acids

An essential amino acid is an amino acid that is required by an organism but cannot be synthesized de novo by it, and therefore must be supplied in its diet. Out of the twenty standard protein-producing amino acids, nine cannot be endogenously synthesized by humans: phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine.

Fatty acids

Essential fatty acids (EFAs) are fatty acids that humans and other animals must ingest because the body requires them for good health but cannot synthesize them. Only two fatty acids are known to be essential for humans: alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid).

Vitamins and vitamers

Vitamins occur in a variety of related forms known as vitamers. The vitamers of a given vitamin perform the functions of that vitamin and prevent symptoms of deficiency of that vitamin. Vitamins are those essential organic molecules that are not classified as amino acids or fatty acids. They commonly function as enzymatic cofactors, metabolic regulators or antioxidants. Humans require thirteen vitamins in their diet, most of which are actually groups of related molecules (e.g. vitamin E includes tocopherols and tocotrienols): vitamins A, C, D, E, K, thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and cobalamin (B12). The requirement for vitamin D is conditional, as people who get sufficient exposure to ultraviolet light, either from the sun or an artificial source, synthesize vitamin D in the skin.

Minerals

Minerals are the exogenous chemical elements indispensable for life. Although the four elements: carbon, hydrogen, oxygen, and nitrogen (CHON) are essential for life, they are so plentiful in food and drink that these are not considered nutrients and there are no recommended intakes for these as minerals. The need for nitrogen is addressed by requirements set for protein, which is composed of nitrogen-containing amino acids. Sulfur is essential, but again does not have a recommended intake. Instead, recommended intakes are identified for the sulfur-containing amino acids methionine and cysteine.

The essential nutrient trace elements for humans, listed in order of Recommended Dietary Allowance (expressed as a mass), are potassium, chloride, sodium, calcium, phosphorus, magnesium, iron, zinc, manganese, copper, iodine, chromium, molybdenum, selenium. Additionally, cobalt is a component of Vitamin B12 which is essential. There are other minerals which are essential for some plants and animals, but may or may not be essential for humans, such as boron and silicon.

Choline

Choline is an essential nutrient. The cholines are a family of water-soluble quaternary ammonium compounds. Choline is the parent compound of the cholines class, consisting of ethanolamine having three methyl substituents attached to the amino function. Healthy humans fed artificially composed diets that are deficient in choline develop fatty liver, liver damage, and muscle damage. Choline was not initially classified as essential because the human body can produce choline in small amounts through phosphatidylcholine metabolism.

Conditionally essential
Conditionally essential nutrients are certain organic molecules that can normally be synthesized by an organism, but under certain conditions in insufficient quantities. In humans, such conditions include premature birth, limited nutrient intake, rapid growth, and certain disease states. Inositol, taurine, arginine, glutamine and nucleotides are classified as conditionally essential and are particularly important in neonatal diet and metabolism.

Non-essential
Non-essential nutrients are substances within foods that can have a significant impact on health. Dietary fiber is not absorbed in the human digestive tract. Soluble fiber is metabolized to butyrate and other short-chain fatty acids by bacteria residing in the large intestine. Soluble fiber is marketed as serving a prebiotic function with claims for promoting "healthy" intestinal bacteria.

Non-nutrients
Ethanol (C2H5OH) is not an essential nutrient, but it does supply approximately  of food energy per gram. For spirits (vodka, gin, rum, etc.) a standard serving in the United States is , which at 40%ethanol (80proof) would be 14 grams and . At 50%alcohol, 17.5 g and . Wine and beer contain a similar amount of ethanol in servings of , respectively, but these beverages also contribute to food energy intake from components other than ethanol. A  serving of wine contains . A  serving of beer contains . According to the U.S. Department of Agriculture, based on NHANES 2013–2014 surveys, women ages 20 and up consume on average 6.8grams of alcohol per day and men consume on average 15.5 grams per day. Ignoring the non-alcohol contribution of those beverages, the average ethanol contributions to daily food energy intake are , respectively. Alcoholic beverages are considered empty calorie foods because, while providing energy, they contribute no essential nutrients.

By definition, phytochemicals include all nutritional and non-nutritional components of edible plants. Included as nutritional constituents are provitamin A carotenoids, whereas those without nutrient status are diverse polyphenols, flavonoids, resveratrol, and lignans that are present in numerous plant foods. Some phytochemical compounds are under preliminary research for their potential effects on human diseases and health. However, the qualification for nutrient status of compounds with poorly defined properties in vivo is that they must first be defined with a Dietary Reference Intake level to enable accurate food labeling, a condition not established for most phytochemicals that are claimed to be antioxidant nutrients.

Deficiencies and toxicity

An inadequate amount of a nutrient is a deficiency. Deficiencies can be due to a number of causes including an inadequacy in nutrient intake, called a dietary deficiency, or any of several conditions that interfere with the utilization of a nutrient within an organism. Some of the conditions that can interfere with nutrient utilization include problems with nutrient absorption, substances that cause a greater than normal need for a nutrient, conditions that cause nutrient destruction, and conditions that cause greater nutrient excretion. Nutrient toxicity occurs when excess consumption of a nutrient does harm to an organism.

In the United States and Canada, recommended dietary intake levels of essential nutrients are based on the minimum level that "will maintain a defined level of nutriture in an individual", a definition somewhat different from that used by the World Health Organization and Food and Agriculture Organization of a "basal requirement to indicate the level of intake needed to prevent pathologically relevant and clinically detectable signs of a dietary inadequacy".

In setting human nutrient guidelines, government organizations do not necessarily agree on amounts needed to avoid deficiency or maximum amounts to avoid the risk of toxicity. For example, for vitamin C, recommended intakes range from 40 mg/day in India to 155 mg/day for the European Union. The table below shows U.S. Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for vitamins and minerals, PRIs for the European Union (same concept as RDAs), followed by what three government organizations deem to be the safe upper intake. RDAs are set higher than EARs to cover people with higher than average needs. Adequate Intakes (AIs) are set when there is not sufficient information to establish EARs and RDAs. Countries establish tolerable upper intake levels, also referred to as upper limits (ULs), based on amounts that cause adverse effects. Governments are slow to revise information of this nature. For the U.S. values, with the exception of calcium and vitamin D, all of the data date from 1997 to 2004.

* The daily recommended amounts of niacin and magnesium are higher than the tolerable upper limit because, for both nutrients, the ULs identify the amounts which will not increase risk of adverse effects when the nutrients are consumed as a serving of a dietary supplement. Magnesium supplementation above the UL may cause diarrhea. Supplementation with niacin above the UL may cause flushing of the face and a sensation of body warmth. Each country or regional regulatory agency decides on a safety margin below when symptoms may occur, so the ULs may differ based on source.

EAR U.S. Estimated Average Requirements.

RDA U.S. Recommended Dietary Allowances; higher for adults than for children, and may be even higher for women who are pregnant or lactating.

AI  U.S. Adequate Intake; AIs established when there is not sufficient information to set EARs and RDAs.

PRI Population Reference Intake is European Union equivalent of RDA; higher for adults than for children, and may be even higher for women who are pregnant or lactating. For Thiamin and Niacin, the PRIs are expressed as amounts per megajoule (239 kilocalories) of food energy consumed.

Upper Limit  Tolerable upper intake levels.

ND  ULs have not been determined.

NE  EARs, PRIs or AIs have not yet been established or will not be (EU does not consider chromium an essential nutrient).

Plant

Plant nutrients consist of more than a dozen minerals absorbed through roots, plus carbon dioxide and oxygen absorbed or released through leaves. All organisms obtain all their nutrients from the surrounding environment.

Plants absorb carbon, hydrogen and oxygen from air and soil in the form of carbon dioxide and water. Other nutrients are absorbed from soil (exceptions include some parasitic or carnivorous plants). Counting these, there are 17 important nutrients for plants: these are macronutrients; nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sulfur (S), magnesium (Mg), carbon (C), oxygen(O) and hydrogen (H), and the micronutrients; iron (Fe), boron (B), chlorine (Cl), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo) and nickel (Ni). In addition to carbon, hydrogen and oxygen; nitrogen, phosphorus, and sulfur are also needed in relatively large quantities. Together, the "Big Six" are the elemental macronutrients for all organisms.
They are sourced from inorganic matter (for example, carbon dioxide, water, nitrates, phosphates, sulfates, and diatomic molecules of nitrogen and, especially, oxygen) and organic matter (carbohydrates, lipids, proteins).
