Supertaster
Supertasters are individuals whose sense of taste for certain flavors and foods, such as chocolate, is far more sensitive than the average person. The term originated with experimental psychologist Linda Bartoshuk and is not the result of response bias or a scaling artifact but appears to have an anatomical Anatomy () is the branch of morphology concerned with the study of the internal structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old scien ... or biological basis. Over the past two decades, the study of many differences in oral sensation has grown to encompass the idea of supertasting. Originally identified as the heightened response to the suprathreshold bitterness of concentrated Propylthiouracil, propylthiouracil (PROP), the contemporary view supports that supertasting encompasses an elevated response to all taste qualities.

Taste
The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste. Taste is the perception stimulated when a substance in the mouth biochemistry, reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with olfaction, the sense of smell and trigeminal nerve stimulation (registering texture, pain, and temperature), determines Flavoring, flavors of food and other substances. Humans have taste receptors on taste buds and other areas, including the upper surface of the tongue and the epiglottis. The gustatory cortex is responsible for the perception of taste. The tongue is covered with thousands of small bumps called lingual papillae, papillae, which are visible to the naked eye. Within each papilla are hundreds of taste buds. The exceptions to this is the filiform papillae that do not contain taste buds. There are between 2000 and 5000Boron, W.F., E.L. Boulpaep. 200 ...

Linda Bartoshuk
Linda May Bartoshuk (born 1938) is an American psychologist. She was born in rural South Dakota in 1938. She is a Presidential Endowed Professor of Community Dentistry and Behavioral Science at the University of Florida. She is an internationally known researcher specializing in the chemical senses of taste and smell, having discovered that some people are supertasters. Biography Bartoshuk grew up in Aberdeen, South Dakota. She received her B.A. from Carleton College and her PhD from Brown University. Her research explores the genetic variations in taste perception and how taste perception affects overall health. Bartoshuk was the first to discover that burning mouth syndrome, a condition predominantly experienced by postmenopausal women, is caused by damage to the taste buds at the front of the tongue and is not a psychosomatic condition. She was employed at Yale University prior to accepting a position at the University of Florida in 2005. Bartoshuk's work at Yale was funde ...

TAS2R38
Taste receptor 2 member 38 is a protein that in humans is encoded by the ''TAS2R38'' gene. TAS2R38 is a bitter (taste), bitter taste receptor; varying genotypes of ''TAS2R38'' influence the ability to taste both propylthiouracil, 6-''n''-propylthiouracil (PROP) and phenylthiocarbamide (PTC). Though it has often been proposed that varying taste receptor genotypes could influence tasting ability, TAS2R38 is one of the few taste receptors shown to have this function. Signal transduction As with all TAS2R proteins, TAS2R38 utilizes the G-protein gustducin as its primary method of signal transduction. Both the α- and βγ-subunits are crucial to the transmission of the taste signal. See: taste receptor. Ligands To date, a total of 23 distinct ligands have been identified for the T2R38 bitter taste receptor. These ligands have been extensively cataloged and documented in the comprehensive database known as BitterDB. Within this repository of bitter taste information, notable ...

Self-diagnosis
Self-diagnosis is the process of diagnosing, or identifying, medical conditions in oneself. It may be assisted by medical dictionaries, books, resources on the Internet, past personal experiences, or recognizing symptoms or medical signs of a condition that a family member previously had or currently has. Depending on the nature of an individual's condition and the accuracy of the information they access, self-diagnoses can vary greatly in their safety. Due to self-diagnoses' varied accuracy, public attitudes toward self-diagnosis include denials of its legitimacy and applause of its ability to promote healthcare access and allow for individuals to find solidarity and support. Furthermore, external influences such as marketing, social media trends, societal stigma around disease, and to which demographic population one belongs greatly affect the use of self-diagnosis. Appropriate use Self-diagnosis is prone to error and may be potentially dangerous if inappropriate decisions are ...

Fungiform Papillae
Lingual papillae (: papilla, ) are small structures on the upper surface of the tongue that give it its characteristic rough texture. The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate. All except the filiform papillae are associated with taste buds. Structure In living subjects, lingual papillae are more readily seen when the tongue is dry. There are four types of papillae present on the tongue in humans: Filiform papillae Filiform papillae () are the most numerous of the lingual papillae. They are fine, small, cone-shaped papillae found on the anterior surface of the tongue. They are responsible for giving the tongue its texture and are responsible for the sensation of touch. Unlike the other kinds of papillae, filiform papillae do not contain taste buds. They cover most of the front two-thirds of the tongue's surface. They appear as very small, conical or cyl ...

Cardiovascular Health
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis. The underlying mechanisms vary depending on the disease. It is estimated that dietary risk factors are associated with 53% of CVD deaths. Coronary artery disease, stroke, and peripheral artery disease involve atherosclerosis. This may be caused by high blood pressure, smoking, diabetes mellitus, lack of exercise, obesity, high blood cholesterol, poor diet, excessive alcohol consumption, and poor sleep, among other things. High blood pressure is estimated to account for approximately 13% of CVD deaths, while tobacco accounts for 9%, diabetes 6%, ...

Body Mass Index
Body mass index (BMI) is a value derived from the mass (Mass versus weight, weight) and height of a person. The BMI is defined as the human body weight, body mass divided by the square (algebra), square of the human height, body height, and is expressed in Units of measurement, units of kg/m2, resulting from mass in kilograms (kg) and height in metres (m). The BMI may be determined first by measuring its components by means of a weighing scale and a stadiometer. The multiplication and division may be carried out directly, by hand or using a calculator, or indirectly using a lookup table (or chart). The table displays BMI as a function of mass and height and may show other units of measurement (converted to Metric system, metric units for the calculation). The table may also show contour lines or colours for different BMI categories. The BMI is a convenient rule of thumb used to broadly categorize a person as based on tissue mass (muscle, fat, and bone) and height. Major adult B ...

Colorectal Cancer
Colorectal cancer (CRC), also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the Colon (anatomy), colon or rectum (parts of the large intestine). Signs and symptoms may include Lower gastrointestinal bleeding, blood in the stool, a change in bowel movements, weight loss, abdominal pain and fatigue. Most colorectal cancers are due to lifestyle factors and genetic disorders. Risk factors include diet, obesity, smoking, and lack of physical activity. Dietary factors that increase the risk include red meat, processed meat, and alcohol (drug), alcohol. Another risk factor is inflammatory bowel disease, which includes Crohn's disease and ulcerative colitis. Some of the inherited genetic disorders that can cause colorectal cancer include familial adenomatous polyposis and hereditary non-polyposis colon cancer; however, these represent less than 5% of cases. It typically starts as a adenoma, benign tumor, often in the form of a colorectal poly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Alcoholic Beverage
Drinks containing alcohol (drug), alcohol are typically divided into three classes—beers, wines, and Distilled beverage, spirits—with alcohol content typically between 3% and 50%. Drinks with less than 0.5% are sometimes considered Non-alcoholic drink, non-alcoholic. Many societies have a distinct drinking culture, where alcoholic drinks are integrated into party, parties. Most countries have Alcohol law, laws regulating the production, sale, and consumption of alcoholic beverages. Some regulations require the labeling of the percentage alcohol content (as ABV or Alcohol proof, proof) and the use of a Alcohol warning label, warning label. List of countries with alcohol prohibition, Some countries Prohibition, ban the consumption of alcoholic drinks, but they are legal in most parts of the world. The temperance movement advocates against the consumption of alcoholic beverages. The global alcohol industry, alcoholic drink industry exceeded $1.5 trillion in 2017. Alcohol is o ...

Alkaloid
Alkaloids are a broad class of natural product, naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. Alkaloids are produced by a large variety of organisms including bacteria, fungus, fungi, Medicinal plant, plants, and animals. They can be purified from crude extracts of these organisms by acid-base extraction, or solvent extractions followed by silica-gel column chromatography. Alkaloids have a wide range of pharmacology, pharmacological activities including antimalarial medication, antimalarial (e.g. quinine), asthma, antiasthma (e.g. ephedrine), chemotherapy, anticancer (e.g. omacetaxine mepesuccinate, homoharringtonine), cholinomimetic (e.g. galantamine), vasodilation, vasodilatory (e.g. vincamine), Antiarrhythmic agent, antiarrhythmic (e.g. quinidine), analgesic (e.g. morphine), antibacterial (e.g. chelerythrine), and anti-diabetic, antihyperglycemic activities (e.g. berb ...
