Nutrition is the study of the relationship between diet and states of health and disease. It is defined as the study of food. Absence of adequate nutrients can cause certain diseases to take hold that can potentially result in death. Between the extremes of optimal health and death from starvation or malnutrition, there is an array of disease states that can be caused or alleviated by changes in diet. Deficiencies, excesses and imbalances in the diet can produce negative impacts on health, which may result in diseases such as s ...

The carrot is a root vegetable, typically orange or white in colour with a woody texture. The edible part of a carrot is a taproot. It is a biennial plant which grows a rosette of leaves in the spring and summer while building up the stout taproot, which stores large amounts of sugars for the plant to flower in the second year. The flowering stem grows to about 1 m tall, with umbels of white flowers. Carrot - Uses. Carrots can be eaten raw, whole, chopped or shaved into salads for colour, and are also often ...

Ill health can be brought about by an imbalance of nutrients, producing either an excess or deficiency which in turn affects body functioning in a cumulative manner. Moreover, because most nutrients are, in some way or the other, involved in cell-to-cell signalling (e.g. as building block or part of a hormone or signalling 'cascades'), deficiency or excess of various nutrients affects hormonal function also indirectly. Thus, because they largely regulate the expression of genes, hormones represent a link between nutrition and how our ...

Carrot cultivars can be grouped into two broad classes, eastern carrots and western carrots. More recently, a number of novelty cultivars have been bred for particular characteristics. Eastern carrots Eastern carrots were domesticated in Central Asia, probably in modern-day Afghanistan in the 10th century or possibly earlier. Those of the eastern carrot that survive to the present day are commonly purple or yellow in colour, and often have branched roots. The purple colour common in these carrots comes from anthocyanin pigments. ...

Melanin deficiency has been connected for some time with various genetic abnormalities and disease states. There are approximately ten different types of oculocutaneous albinism, which is mostly an autosomal recessive disorder. Certain ethnicities have higher incidences of different forms. For example, the most common type, the OCA2 (or tyrosinase positive) albinism, is especially frequent among people of indigenous African descent. It is an autosomal recessive disorder characterized by a congenital reduction or absence of melanin pig ...

Isoprene is formed naturally in animals and plants and is generally the most common hydrocarbon found in the human body. The estimated production rate of isoprene in the human body is 15 µmol/kg/h, equivalent to approximately 17 mg/day for a 70 kg person. Isoprene is also common in low concentrations in many foods. Isoprene is produced in the chloroplasts of leaves of certain tree species through the DMAPP pathway; the enzyme isoprene synthase is responsible for its biosynthesis. The amount of isoprene released from isoprene-emitting vegeta ...

Since the Industrial Revolution some two hundred years ago, the food processing industry has invented many technologies that both help keep foods fresh longer and alter the fresh state of food as they appear in nature. Cooling is the primary technology that can help maintain freshness, whereas many more technologies have been invented to allow foods to last longer without becoming spoiled. These latter technologies include pasteurisation, autoclavation, drying, salting, and separation of various components, and all appear to alter the origin ...

The human body comprises chemical compounds such as water, amino acids (proteins), fatty acids (lipids), nucleic acids (DNA/RNA), and carbohydrates (e.g. sugars). These compounds in turn consist of elements such as carbon, hydrogen, oxygen, nitrogen, and phosphorus, and may or may not contain minerals such as calcium, iron, and zinc. Minerals ubiquitously occur in the form of salts and electrolytes. All of these chemical compounds and elements occur in various forms and combinations (e.g. hormones/vitamins, phospholipids, hydroxyapatite), both in the human body and in organisms ( ...

Nutrition - Calorie restriction. Lifespan may be somehow related to the amount of food energy consumed: this was first systematically investigated in the seminal study by Weidruch, et al. (1986). A pursuit of this principle of caloric restriction followed, involving research into longevity of those who reduced their food energy intake while attempting to optimize their micronutrient intake. Perhaps not surprisingly, some people found that cutting down on food reduced their quality of life so considerably as to ne ...

Nutrition is very important for improving sports performance. The most common means to improve performance through diet is the practice of eating large quantities of protein, usually red meat, when attempting to build muscle mass; its efficacy is doubtful, as daily protein intake even on a normal diet usually outweighs the amount of muscle protein which can be synthesized in a day. To enhance their speed of muscle synthesis, athletes will focus a great deal on how to best accelerate their tissue recovery. Icing/heating the muscles to ...

HMG-CoA reductase inhibitors, also known as the group of cholesterol-lowering drugs called statins, inhibit the synthesis of mevalonate. Mevalonate is a precursor to isopentenyl pyrophosphate, which combines with its isomer, dimethylallyl pyrophosphate, in repeating alternations to form isoprene (or polyprenyl) chains. Statins are used to lower cholesterol, which is synthesized from the 15-carbon isoprenoid, farnesyl pyrophosphate, but also inhibit all other isoprenes, including coenzyme Q10. This flow chartshows the biosynthesis of ...

In humans, melanin is found in skin, hair, the coat of the retina, the renal medulla and zona reticularis of the adrenal gland, the inner ear, and the substantia nigra (in Latin, literally "black substance") and locus ceruleus ("blue spot") of the brain. Melanin is the primary determinant of human skin color. Dermal melanin is produced by melanocytes, which are found in the stratum basale of the epidermis. Although human beings generally possess a similar concentration of melanocytes in their skin, the melanocytes in some individuals ...
