Micro-nutrient
Micronutrients are essential dietary elements required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain health. Micronutrient requirements differ between organisms; for example, humans and other animals require numerous vitamins and dietary minerals, whereas plants require specific minerals. For human nutrition, micronutrient requirements are in amounts generally less than 100 milligrams per day, whereas macronutrients are required in gram quantities daily. The minerals for humans and other animals include 13 elements that originate from Earth's soil and are not synthesized by living organisms, such as calcium and iron. Micronutrient requirements for animals also include vitamins, which are organic compounds required in microgram or milligram amounts. Since plants are the primary origin of nutrients for humans and animals, some micronutrients may be in low levels and deficiencies can occur when dietary intake is insuf ...

Human Nutrition
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. Poor nutrition is a chronic problem often linked to poverty, food security, or a poor understanding of nutritional requirements.Progress for Children: A Report Card on Nutrition (No. 4), UNICEF, May 2006, www.ventes.le-vel.ca /nutrition/index_33685.html Malnutrition and its consequences are large contributors to deaths, physical deformities, and disabilities worldwide.World Health Organization.

Soil
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nutrient
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micronutrient Initiative
Nutrition International, formerly the Micronutrient Initiative (MI), is an international not for profit agency based in Canada that works to eliminate vitamin and mineral deficiencies in developing countries. Although often only required by the body in very small amounts, vitamin and minerals – also known as micronutrients – support an array of critical biological functions including growth, immune function and eye function, as well as foetal development of the brain, the nervous system, and the skeletal system. Micronutrient deficiency is a form of malnutrition and is a recognized health problem in many developing countries. Globally, more than two billion people live with vitamin and mineral deficiencies. History In 1990, leaders attending the World Summit for Children set the goal of virtually eliminating micronutrient deficiencies. In 1992, Micronutrient Initiative was established as a secretariat within the International Development Research Centre (IDRC), based in Ottawa, ...

Levente Diosady
Levente (between 1010 and 1015 – 1047) was a member of the House of Árpád, a great-grandson of Taksony, Grand Prince of the Hungarians. He was expelled from Hungary in 1031 or 1032, and spent many years in Bohemia, Poland and the Kievan Rus'. He returned to Hungary, where a pagan uprising was developing around that time, in 1046. Levente remained a devout pagan, but did not hinder the election of his Christian brother, Andrew I as king. Childhood Hungarian chronicles have preserved contradictory information of his parentage. According to one variant, Levente and his two brothersAndrew and Bélawere "the sons of Ladislas the Bald"''The Hungarian Illuminated Chronicle:'' (ch. 60.87), p. 113. and his "wife from Ruthania", that is from the Kievan Rus'. On the other hand, a concurring tradition has preserved that the three brothers were sons of Ladislas the Bald's brother, "Vazul by some girl from the clan" of Tátony. Modern historians – since the research of Péter Váczy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Toronto
The University of Toronto (UToronto or U of T) is a public research university in Toronto, Ontario, Canada, located on the grounds that surround Queen's Park. It was founded by royal charter in 1827 as King's College, the first institution of higher learning in Upper Canada. Originally controlled by the Church of England, the university assumed its present name in 1850 upon becoming a secular institution. As a collegiate university, it comprises eleven colleges each with substantial autonomy on financial and institutional affairs and significant differences in character and history.

USAID
The United States Agency for International Development (USAID) is an independent agency of the U.S. federal government that is primarily responsible for administering civilian foreign aid and development assistance. With a budget of over $27 billion, USAID is one of the largest official aid agencies in the world and accounts for more than half of all U.S. foreign assistance—the highest in the world in absolute dollar terms. Congress passed the Foreign Assistance Act on September 4, 1961, which reorganized U.S. foreign assistance programs and mandated the creation of an agency to administer economic aid. USAID was subsequently established by the executive order of President John F. Kennedy, who sought to unite several existing foreign assistance organizations and programs under one agency. USAID became the first U.S. foreign assistance organization whose primary focus was long-term socioeconomic development. USAID's programs are authorized by Congress in the Foreign Assistanc ...

Iodine
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at , and boils to a violet gas at . The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek 'violet-coloured'. Iodine occurs in many oxidation states, including iodide (I−), iodate (), and the various periodate anions. It is the least abundant of the stable halogens, being the sixty-first most abundant element. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. The dominant producers of iodine today are Chile and Japan. Due to its high atomic number and ease of attachment to organic compound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Iodization
Iodised salt ( also spelled iodized salt) is table salt mixed with a minute amount of various salts of the element iodine. The ingestion of iodine prevents iodine deficiency. Worldwide, iodine deficiency affects about two billion people and is the leading preventable cause of intellectual and developmental disabilities. Deficiency also causes thyroid gland problems, including endemic goitre. In many countries, iodine deficiency is a major public health problem that can be cheaply addressed by purposely adding small amounts of iodine to the sodium chloride salt. Iodine is a micronutrient and dietary mineral that is naturally present in the food supply in some regions, especially near sea coasts but is generally quite rare in the Earth's crust since iodine is a so-called heavy element, and abundance of chemical elements generally declines with greater atomic mass. Where natural levels of iodine in the soil are low and the iodine is not taken up by vegetables, iodine added to salt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
