Nutrition
Nutrition is the biochemical process whereby an organism uses food to sustain life. It provides organisms with nutrients that can be digested to generate energy and chemical structures. The inability to provide adequate amounts of nutrients leads to a poor diet. Nutritional science is the study of nutrition.
Its kind of organism determines which nutrients are required and how they are acquired.
This way, organisms get their nutrients by consuming organic matter or inorganic matter, absorbing light, or possibly a combination of the two. Some can produce nutrients internally by consuming basic elements. All life forms require consuming organic matter, and inorganic matter, absorbing light carbon, energy, water, and also a variety of molecules. Animals require more complicated nutrients, such as carbohydrates, lipids, proteins, nutrition, and vitamins. These nutrients are replaced by consuming other organisms. Humans have been able to develop agriculture and cooking instead of foraging to supplement human nutrition. Plants obtain nutrients through the soil and from the atmosphere. Fungi can get their nutrients around themselves by decomposition and absorption in the mycelium.
Aliments
Composting in agricultural systems exploits the natural ecosystem services of nutrient recycling in ecosystems. Bacteria, fungi, insects, earthworms, bugs, among others, dig and digest compost into fertile soil. The minerals and nutrients in the soil are reused back into the production of crops.
They are substances that provide energy and physical parts to the organism to make it survive, grow, and reproduce. Such nutrients can be either simple elements or complex macromolecules.
Approximately 30 elements are found in organic matter. Of these, the three most important are nitrogen, carbon, and phosphorus. Those substances an organism requires the greatest amount of are known as macronutrients. Trace amounts are needed, and the substance is referred to as a micronutrient. Organic micronutrients are classified as vitamins. The inorganic micronutrients are classified as minerals.
Fuel such chemical reactions used in metabolic biochemical by providing the nutrients to feed fuel reactions for the formation of precursor metabolites and the yield of energy, biosynthesis that involves the conversion of metabolite precursors into building-block molecules, polymerization as far as combining the molecules into macro polime r-formations, assembles used in the construction process with formation of cellular structures.
Feeding
Feeding refers to the intake of food by an animal outside into an organism in nutrition sphere. In general, diet is crucial for the overall improvement of physical and mental health of an organism. Through diet, it derives vitamins, minerals, proteins having essential amino acids, and fats having essential fatty acids. The most important components of quality of life, health, and survival are carbs, proteins, and fat. Some cultures and religions restrict what is acceptable for their diet.
Aliments cycle
A nutrient cycle is a biogeochemical cycle whereby inorganic matter is transferred through a combination of soil, organisms, air, or water where they are exchanged in organic matter.
Mineral nutrients movement is cyclic, whereas the flow of energy is a one-way and noncyclic pathway. Some mineral cycles include the carbon cycle, sulfur cycle, nitrogen cycle, water cycle, phosphorus cycle, and oxygen cycle, among others that regularly recycle along with other mineral aliments into productive ecological nutrition.
These cycles of water, carbon, nitrogen, phosphorus, sulfur, carried out by living organisms and natural processes, include the nutrient cycles. These cycles enable necessary elements to return to the environment following absorption or consumption. There would be a risk of change in oxygen levels, climate, and ecosystem function without nutrient cycling.
Human
Early human nutrition was highly similar to that of other animals in the sense of scrounging for nutrients but diverged at the onset of the Holocene with the Neolithic Revolution, where humans began to cultivate agriculture in order to produce food. The Chemical Revolution in the 18th century gave human beings the ability to understand the nutrients in foods and create more sophisticated techniques of food preparation.
The mass production and food fortification in the 20th century were enabled by major advances in economics and technology, which allowed them to more comprehensively meet human nutritional needs. Human behavior is intimately associated with human nutrition, hence nutrition is also a subject of social science, aside from its biology. Optimal diet varies according to the demographics and health concerns of each individual as it is balanced by eating for pleasure.
Human is an omnivore that consumes various types of food. Since the early times of agriculture, making bread was one of the major things that humans were involved in their nutrition habits. Early man used to hunt for meat from wild animals. Modern humans get their meat and eggs from domesticated animals. The humans were also able to take the milk from other animals for culture and further process it to edible foods such as cheese in some cultures.
Other types of foods eaten by man are nuts, seeds, fruits, and vegetables. The increase of consumed fats and oils by the existence of domesticated animals and vegetable oils is unbelievable. The ways to elaborate food processing have reduced the entry of harmful microbes into human diet. The preparation has become very simple. Some of the important ones are drying, freezing, heating, grinding, pressing, packaging, refrigeration, and irradiation. Most of the cultures spice the food items with herbs and spices before eating for the taste. Most of them are negligible in terms of nutritional values, but some others increase the food quality and safety, nutritional quality, safety, and palatability.
CONCLUSION
Most carbs are obtained by humans from cereal starch, although sugar is more important now. Fat is found in animal fats as well as butterfat and vegetable oil and lipids and leafy vegetables while it is also used in enhancing flavor in foods. Proteins are found in almost every single food since they make up tissue structure, though certain food-processing methods can eliminate some content of protein in a particular food.
Ethanol is also an energy source to humans, although it is a food and a drug it provides relatively few essential nutrients and is associated with nutritional deficiencies as well as other health risks.
Such diseases associated with deficiency in humans are blindness, anemia, scurvy, preterm birth, stillbirth, cretinism, or other conditions of excess nutrient states such as obesity and metabolic syndrome. Other conditions potentially involved are cardiovascular disease, diabetes, and osteoporosis. In acute undernutrition, the state results in wasting, whereas chronic malnutrition leads to marasmus.
