Grapefruit Diet
The Grapefruit diet (also known as the Hollywood diet and the 18-Day diet) is a short-term fad diet that has existed in the United States since at least the 1930s. There are variations on the diet, although it generally consists of eating one grapefruit at each meal, along with meat, eggs, other foods that are rich in fat and protein, and certain vegetables. Sugar, fruits (other than grapefruit), sweet vegetables, grains and starchy vegetables are to be avoided. The grapefruit diet is thus a low-carbohydrate diet. A typical breakfast menu usually includes bacon and eggs. The diet is based on the claim that grapefruit has a fat-burning enzyme or similar property. The grapefruit diet does not require exercise. The grapefruit diet lasts for 10 to 12 days followed by 2 days off. History The grapefruit diet originated in the 1930s. It was originally known in 1929 as the "eighteen-day diet", and featured 18 days of grapefruit, orange, toast, vegetable and egg combinations, totalling ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the "Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chemi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fad Diets
A fad diet is a diet that becomes popular for a short time, similar to fads in fashion, without being a standard dietary recommendation, and often making unreasonable claims for fast weight loss or health improvements. There is no single definition of what is a fad diet. The term fad diet encompasses a variety of diets with different approaches and evidence bases, and thus different outcomes, advantages, and disadvantages. Generally, fad diets promise an assortment of short-term changes requiring little to no effort; attracting the interests of uneducated consumers about whole-diet, whole-lifestyle changes necessary for sustainable health benefices. Fad diets are often promoted with exaggerated claims, such as rapid weight loss of more than 1 kg/week, improving health by "detoxification", or even dangerous claims, such as highly restrictive and nutritionally unbalanced food choices leading to malnutrition or eating non-food items like cotton wool.

Grapefruit
The grapefruit (''Citrus'' × ''paradisi'') is a subtropical citrus tree known for its relatively large, sour to semi-sweet, somewhat bitter fruit. The interior flesh is segmented and varies in color from pale yellow to dark pink. Grapefruit is a citrus hybrid originating in Barbados. It is an accidental cross between the sweet orange (''C. sinensis'') and the pomelo or shaddock (''C. maxima''), both of which were introduced from Asia in the 17th century. It has also been called the '' forbidden fruit''. In the past it was referred to as the ''pomelo'', but that term is now mostly used as the common name for ''Citrus maxima''. In 2019, world production of grapefruits (combined with pomelos) was 9.3 million tonnes, of which 53% was in China. Other significant producers include Vietnam, United States and Mexico. Description The evergreen grapefruit trees usually grow to around tall, although they may reach . The leaves are long (up to ), thin, glossy, and dark green. They p ...

Diets
The Low Countries comprise the coastal Rhine–Meuse–Scheldt delta region in Western Europe, whose definition usually includes the modern countries of Luxembourg, Belgium and the Netherlands. Both Belgium and the Netherlands derived their names from earlier names for the region, due to ''nether'' meaning "low" and ''Belgica'' being the Latinized name for all the Low Countries, a nomenclature that became obsolete after Belgium's secession in 1830. The Low Countries—and the Netherlands and Belgium—had in their history exceptionally many and widely varying names, resulting in equally varying names in different languages. There is diversity even within languages: the use of one word for the country and another for the adjective form is common. This holds for English, where ''Dutch'' is the adjective form for the country "the Netherlands". Moreover, many languages have the same word for both the country of the Netherlands and the region of the Low Countries, e.g., French (' ...

List Of Fad Diets
An individual's diet is the sum of food and drink that one habitually consumes. Dieting is the practice of attempting to achieve or maintain a certain weight through diet. People's dietary choices are often affected by a variety of factors, including ethical and religious beliefs, clinical need, or a desire to control weight. Not all diets are considered healthy. Some people follow unhealthy diets through habit, rather than through a conscious choice to eat unhealthily. Terms applied to such eating habits include "junk food diet" and "Western diet". Many diets are considered by clinicians to pose significant health risks and minimal long-term benefit. This is particularly true of "crash" or "fad" diets – short-term, weight-loss plans that involve drastic changes to a person's normal eating habits. ''Only diets covered on Wikipedia are listed under alphabetically sorted headings''. Belief-based diets Some people's dietary choices are influenced by their religious, spiritual or ...

Grapefruit–drug Interactions
Some fruit juices and fruits can interact with numerous drugs, in many cases causing adverse effects. The effect is most studied with grapefruit and grapefruit juice, but similar effects have been observed with certain other citrus fruits. The effect was first discovered accidentally in 1991, when a test of drug interactions with alcohol used grapefruit juice to hide the taste of the ethanol. A 2005 medical review advised patients to avoid all citrus juices until further research clarifies the risks. It was reported in 2008 that similar effects had been observed with apple juice. One whole grapefruit, or a small glass () of grapefruit juice, can cause drug overdose toxicity. Fruit consumed three days before the medicine can still have an effect. The relative risks of different types of citrus fruit have not been systematically studied. Affected drugs typically have an auxiliary label saying "''Do not take with grapefruit''" on the container, and the interaction is elaborat ...

Lewis Wolberg
Lewis Robert Wolberg (July 4, 1905 – February 3, 1988) was an American psychoanalyst. He advocated the use of hypnoanalysis in psychiatric treatment. He wrote or edited 20 books, and in 1945 founded the Postgraduate Center for Mental Health in New York City. In 1927, Wolberg graduated from the University of Rochester and obtained his M.D. from Tufts University School of Medicine in 1930. From 1967 to 1986, he was professor of psychiatry at the New York University School of Medicine. Wolberg was also interested in dieting and nutrition. He authored ''The Psychology of Eating'' in 1936.

Vitamin A
Vitamin A is a fat-soluble vitamin and an essential nutrient for humans. It is a group of organic compounds that includes retinol, retinal (also known as retinaldehyde), retinoic acid, and several provitamin A carotenoids (most notably beta-carotene -carotene. Vitamin A has multiple functions: it is essential for embryo development and growth, for maintenance of the immune system, and for vision, where it combines with the protein opsin to form rhodopsin the light-absorbing molecule necessary for both low-light ( scotopic vision) and color vision. Vitamin A occurs as two principal forms in foods: A) retinol, found in animal-sourced foods, either as retinol or bound to a fatty acid to become a retinyl ester, and B) the carotenoids alpha-carotene, β-carotene, gamma-carotene, and the xanthophyll beta-cryptoxanthin (all of which contain β-ionone rings) that function as provitamin A in herbivore and omnivore animals which possess the enzymes that cleave and con ...

Iron Deficiency
Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen enzyme reactions in various tissues. Too little iron can interfere with these vital functions and lead to morbidity and death. Total body iron averages approximately 3.8 g in men and 2.3 g in women. In blood plasma, iron is carried tightly bound to the protein transferrin. There are several mechanisms that control iron metabolism and safeguard against iron deficiency. The main regulatory mechanism is situated in the gastrointestinal tract. The majority of iron absorption occurs in the duodenum, the first section of the small intestine. A number of dietary factors may affect iron absorpt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcium
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin ''calx'' " lime", which was obtained from heating limestone. Some calcium compounds were known to the ancients, though their chemistry was unknown until the seventeenth century. Pure calcium was isolated in 1808 via electrolysis of its oxide by Humphry Davy, who named the element. Calcium compounds are widely used in many industries: in foods and p ...
