Zone Diet
The Zone diet is a fad diet emphasizing low-carbohydrate consumption. It was created by Barry Sears, an American biochemist.Baron M. Fighting obesity Part 1: Review of popular low-carb diets. Health Care Food Nutr Focus. 2004 Oct;21(10):1, 3-6, 11. Review. Baron M. The Zone Diet. Health Care Food Nutr Focus. 2004 Oct;21(10):8-9, 11. The ideas behind the diet are not supported by scientific evidence.Cataldo, Corrine Balog; DeBruyne, Linda Kelly; Whitney, Eleanor Noss. (1999). ''Nutrition and Diet Therapy: Principles and Practice''. West/Wadsworth. p. 214. "Most fad diets, including the currently popular Zone Diet, advocate essentially the same high-protein, low- carbohydrate diet. Such diets may offer short-term weight- loss success to some who try them, but they fail to produce long-lasting results for most people. Furthermore, high protein, low-carbohydrate diets are often high in fat and low in fiber, vitamins, and some minerals. Long-term use of such diets may produce adverse ...

Fad Diet
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. Highly restrictive fad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-carbohydrate Diet
Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet. Foods high in carbohydrates (e.g., sugar, bread, pasta) are limited, and replaced with foods containing a higher percentage of fat and protein (e.g., meat, poultry, fish, shellfish, eggs, cheese, nuts, and seeds), as well as low carbohydrate foods (e.g. spinach, kale, chard, collards, and other fibrous vegetables). There is a lack of standardization of how much carbohydrate low-carbohydrate diets must have, and this has complicated research. One definition, from the American Academy of Family Physicians, specifies low-carbohydrate diets as having less than 20% of calories from carbohydrates. There is no good evidence that low-carbohydrate dieting confers any particular health benefits apart from weight loss, where low-carbohydrate diets achieve outcomes similar to other diets, as weight loss is mainly determined by calorie restriction and adherence. An extreme form of low-carbohydrate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barry Sears
Barry Sears (born June 6, 1947) is an American biochemist and author best known for creating and promoting the Zone diet, a low-carbohydrate fad diet that is not supported by good medical evidence.Cataldo, Corrine Balog; DeBruyne, Linda Kelly; Whitney, Eleanor Noss. (1999). ''Nutrition and Diet Therapy: Principles and Practice''. West/Wadsworth. p. 214. "Most fad diets, including the currently popular Zone Diet, advocate essentially the same high-protein, low- carbohydrate diet... Long-term use of such diets may produce adverse side effects such as nausea, fatigue, constipation, and low blood pressure." Biography As stated in several of his books, the Zone diet was born of his desire to avoid an early death from a premature heart attack, a fate of which all other men in his family had been early victims. In more recent years, Sears has popularized the use of high-dose Omega-3 fatty acids and polyphenols to further reduce inflammation. He began studying lipids primarily beca ...

Biochemist
Biochemists are scientists who are trained in biochemistry. They study chemical processes and chemical transformations in living organisms. Biochemists study DNA, proteins and cell parts. The word "biochemist" is a portmanteau of "biological chemist." Biochemists also research how certain chemical reactions happen in cells and tissues and observe and record the effects of products in food additives and medicines. Biochemist researchers focus on playing and constructing research experiments, mainly for developing new products, updating existing products and analyzing said products. It is also the responsibility of a biochemist to present their research findings and create grant proposals to obtain funds for future research. Biochemists study aspects of the immune system, the expressions of genes, isolating, analyzing, and synthesizing different products, mutations that lead to cancers, and manage laboratory teams and monitor laboratory work. Biochemists also have to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glycemic Index
The glycemic (glycaemic) index (GI; ) is a number from 0 to 100 assigned to a food, with pure glucose arbitrarily given the value of 100, which represents the relative rise in the blood glucose level two hours after consuming that food. The GI of a specific food depends primarily on the quantity and type of carbohydrate it contains, but is also affected by the amount of entrapment of the carbohydrate molecules within the food, the fat and protein content of the food, the amount of organic acids (or their salts) in the food, and whether it is cooked and, if so, how it is cooked. GI tables, which list many types of foods and their GIs, are available. A food is considered to have a ''low GI'' if it is 55 or less; ''high GI'' if 70 or more; and ''mid-range GI'' if 56 to 69. The term was introduced in 1981 by David J. Jenkins and co-workers. It is useful for quantifying the relative rapidity with which the body breaks down carbohydrates. It takes into account only the available carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monounsaturated Fats
In nutrition, biology, and chemistry, fat usually means any ester of fatty acids, or a mixture of such compounds, most commonly those that occur in living beings or in food. The term often refers specifically to triglycerides (triple esters of glycerol), that are the main components of vegetable oils and of fatty tissue in animals; or, even more narrowly, to triglycerides that are solid or semisolid at room temperature, thus excluding oils. The term may also be used more broadly as a synonym of lipid—any substance of biological relevance, composed of carbon, hydrogen, or oxygen, that is insoluble in water but soluble in non-polar solvents. In this sense, besides the triglycerides, the term would include several other types of compounds like mono- and diglycerides, phospholipids (such as lecithin), sterols (such as cholesterol), waxes (such as beeswax), and free fatty acids, which are usually present in human diet in smaller amounts. Fats are one of the three mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USDA
The United States Department of Agriculture (USDA) is the federal executive department responsible for developing and executing federal laws related to farming, forestry, rural economic development, and food. It aims to meet the needs of commercial farming and livestock food production, promotes agricultural trade and production, works to assure food safety, protects natural resources, fosters rural communities and works to end hunger in the United States and internationally. It is headed by the Secretary of Agriculture, who reports directly to the President of the United States and is a member of the president's Cabinet. The current secretary is Tom Vilsack, who has served since February 24, 2021. Approximately 80% of the USDA's $141 billion budget goes to the Food and Nutrition Service (FNS) program. The largest component of the FNS budget is the Supplemental Nutrition Assistance Program (formerly known as the Food Stamp program), which is the cornerstone of USD ...

Food Pyramid (nutrition)
A food pyramid is a representation of the optimal number of servings to be eaten each day from each of the basic food groups. The first pyramid was published in Sweden in 1974. The 1992 pyramid introduced by the United States Department of Agriculture (USDA) was called the "Food Guide Pyramid" or "Eating Right Pyramid". It was updated in 2005 to " MyPyramid", and then it was replaced by " MyPlate" in 2011. Swedish origin Amid high food prices in 1972, Sweden's National Board of Health and Welfare developed the idea of "basic foods" that were both cheap and nutritious, and "supplemental foods" that added nutrition missing from the basic foods. Anna-Britt Agnsäter, chief of the "test kitchen" for Kooperativa Förbundet (a cooperative Swedish retail chain), held a lecture the next year on how to illustrate these food groups. Attendee Fjalar Clemes suggested a triangle displaying basic foods at the base. Agnsäter developed the idea into the first food pyramid, which was intr ...

Atkins Diet
The Atkins diet is a low-carbohydrate fad diet devised by Robert Atkins in the 1970s, marketed with claims that carbohydrate restriction is crucial to weight loss and that the diet offered "a high calorie way to stay thin forever". The diet became popular in the early 2000s, with Atkins' book becoming one of the top 50 best-selling books in history, and as many as 1 in 11 North American adults claiming to be following it. Atkins died in 2003 and in 2005 Atkins Nutritionals, Inc. filed for bankruptcy following substantial financial losses. There is no good evidence of the diet's effectiveness in achieving durable weight loss; it is unbalanced as it promotes unlimited consumption of protein and saturated fat, and it may increase the risk of heart disease.Longe, Jacqueline L.

Diet (nutrition)
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity. Health A healthy diet can improve and maintain health, which can include aspects of mental and physical health. Specific diets, such as the DASH diet, can be used in treatment and management of chronic conditions. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of 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 ...

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 ( ...
