Pregnancy Craving
A food craving (also called selective hunger) is an intense desire to consume a specific food, and is different from normal hunger. It may or may not be related to specific hunger, the drive to consume particular nutrients that is well-studied in animals. In studies of food cravings, chocolate and chocolate confectioneries almost always top the list of foods people say they crave; this craving is referred to as chocoholism. The craving of non-food items as food is called pica. Causes A food craving is a strong desire to eat a particular type of food. This desire can seem uncontrollable, and the person’s hunger may not be satisfied until they get that particular food. Food cravings are common. One research found that 97% of women and 68% of men reported experiencing food cravings. There is no single explanation for food cravings, and explanations range from low serotonin levels affecting the brain centers for appetite to production of endorphins as a result of consuming fats ...

Hunger (physiology)
Hunger is a sensation that motivates the consumption of food. The sensation of hunger typically manifests after only a few hours without eating and is generally considered to be unpleasant. Satiety occurs between 5 and 20 minutes after eating. There are several theories about how the feeling of hunger arises. The desire to eat food, or appetite, is another sensation experienced with regard to eating. The term ''hunger'' is also the most commonly used in social science and policy discussions to describe the condition of people who suffer from a chronic lack of sufficient food and constantly or frequently experience the sensation of hunger, and can lead to malnutrition. A healthy, well-nourished individual can survive for weeks without food intake (see fasting), with claims ranging from three to ten weeks. Satiety is the opposite of hunger; it is the sensation of feeling full. Hunger pangs The physical sensation of hunger is related to the contractions of the muscles of the ...

Vitamin
Vitamins are Organic compound, organic molecules (or a set of closely related molecules called vitamer, vitamers) that are essential to an organism in small quantities for proper metabolism, metabolic function. Nutrient#Essential nutrients, Essential nutrients cannot be biosynthesis, synthesized in the organism in sufficient quantities for survival, and therefore must be obtained through the Diet (nutrition), diet. For example, vitamin C can be synthesized by some species but not by others; it is not considered a vitamin in the first instance but is in the second. Most vitamins are not single molecules, but groups of related molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols. The term ''vitamin'' does not include the three other groups of essential nutrients: mineral (nutrient), minerals, essential fatty acids, and essential amino acids. Major health organizations list thirteen vitamins: * Vitamin A (all-' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birthmark
A birthmark is a congenital, benign irregularity on the skin which is present at birth or appears shortly after birth—usually in the first month. Birthmarks can occur anywhere on the skin. They are caused by overgrowth of blood vessels, melanocytes, smooth muscle, fat, fibroblasts, or keratinocytes. Dermatologists divide birthmarks into two types: pigmented birthmarks and vascular birthmarks. Pigmented birthmarks caused by excess skin pigment cells include: moles, café au lait spots, and Mongolian spots. Vascular birthmarks, also called red birthmarks, are caused by increased blood vessels and include macular stains (salmon patches), hemangiomas, and port-wine stains. A little over 1 in 10 babies have a vascular birthmark present by age 1. Several birthmark types are part of the group of skin lesions known as nevi or naevi, which is Latin for "birthmarks". Birthmarks occur as a result of a localized imbalance in factors controlling the development and migration of skin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hmong People
The Hmong people ( RPA: , CHV: ''Hmôngz'', Nyiakeng Puachue: , Pahawh Hmong: , , zh, c=苗族蒙人) are an indigenous group in East Asia and Southeast Asia. In China, the Hmong people are classified as a sub-group of the Miao people. The modern Hmong reside mainly in Southwestern China and Mainland Southeast Asian countries such as Vietnam, Laos, Thailand, and Myanmar. There are also diaspora communities in the United States, Australia, France, and South America. Etymology The term ''Hmong'' is the English pronunciation of the Hmong's native name. It is a singular and plural noun (e.g., Japanese, French, etc.). Very little is known about the native Hmong name as it is not mentioned in Chinese historical records, since the Han identified the Hmong as Miao.

Anemia
Anemia (also spelt anaemia in British English) is a blood disorder in which the blood has a reduced ability to carry oxygen. This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function. The name is derived . When anemia comes on slowly, the symptoms are often vague, such as Fatigue, tiredness, weakness, shortness of breath, headaches, and a Exercise intolerance, reduced ability to exercise. When anemia is acute, symptoms may include confusion, lightheadedness, feeling like one is going to pass out, Syncope (medicine), loss of consciousness, and polydipsia, increased thirst. Anemia must be significant before a person becomes noticeably Pallor, pale. Additional symptoms may occur depending on the underlying cause. Anemia can be temporary or long term and can range from mild to severe. Anemia can be caused by blood loss, decreased red blood cel ...

Pica (disorder)
Pica ("PIE-kuh"; IPA: /ˈpaɪkə/) is the craving or consumption of objects that are not normally intended to be consumed. It is classified as an eating disorder but can also be the result of an existing mental disorder. The ingested or craved substance may be biological, natural, or manmade. The term was drawn directly from the medieval Latin word for magpie, a bird subject to much folklore regarding its opportunistic feeding behaviors. According to the '' Diagnostic and Statistical Manual of Mental Disorders, 5th Edition'' (DSM-5), pica as a standalone eating disorder must persist for more than one month at an age when eating such objects is considered developmentally inappropriate, not part of culturally sanctioned practice, and sufficiently severe to warrant clinical attention. Pica may lead to intoxication in children, which can result in an impairment of both physical and mental development. In addition, it can cause surgical emergencies to address intestinal obstruction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fast Food
Fast food is a type of Mass production, mass-produced food designed for commercial resale, with a strong priority placed on speed of service. ''Fast food'' is a commercial term, limited to food sold in a restaurant or store with frozen, preheated or precooked ingredients and served in packaging for take-out or takeaway. Fast food was created as a commercial strategy to accommodate large numbers of busy commuters, travelers and Wage, wage workers. In 2018, the fast-food industry was worth an estimated $570 billion globally. The fastest form of "fast food" consists of pre-cooked meals which reduce waiting periods to mere seconds. Other fast-food outlets, primarily hamburger outlets such as McDonald's and Burger King, use mass-produced, pre-prepared ingredients (bagged buns and condiments, frozen beef patties, vegetables which are pre-washed, pre-sliced, or both; etc.) and cook the meat and french fries fresh, before assembling "to order". Fast-food restaurants are traditionally d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calorie
The calorie is a unit of energy that originated from the caloric theory of heat. The large calorie, food calorie, dietary calorie, kilocalorie, or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius (or one kelvin). The small calorie or gram calorie is defined as the amount of heat needed to cause the same increase in one milliliter of water. Thus, 1 large calorie is equal to 1,000 small calories. In nutrition and food science, the term ''calorie'' and the symbol ''cal'' may refer to the large unit or to the small unit in different regions of the world. It is generally used in publications and package labels to express the energy value of foods in per serving or per weight, recommended dietary caloric intake, metabolic rates, etc. Some authors recommend the spelling ''Calorie'' and the symbol ''Cal'' (both with a capital C) if the large calorie is meant, to avoid confusion; however, this convention ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

Sweets
Candy, alternatively called sweets or lollies, is a confection that features sugar as a principal ingredient. The category, also called ''sugar confectionery'', encompasses any sweet confection, including chocolate, chewing gum, and sugar candy. Vegetables, fruit, or nuts which have been glazed and coated with sugar are said to be '' candied''. Physically, candy is characterized by the use of a significant amount of sugar or sugar substitutes. Unlike a cake or loaf of bread that would be shared among many people, candies are usually made in smaller pieces. However, the definition of candy also depends upon how people treat the food. Unlike sweet pastries served for a dessert course at the end of a meal, candies are normally eaten casually, often with the fingers, as a snack between meals. Each culture has its own ideas of what constitutes candy rather than dessert. The same food may be a candy in one culture and a dessert in another. History The word candy entered the Eng ...

Morning Sickness
Morning sickness, also called nausea and vomiting of pregnancy (NVP), is a symptom of pregnancy. Despite the name, nausea or vomiting can occur at any time during the day. Typically the symptoms occur between the 4th and 16th weeks of pregnancy. About 10% of women still have symptoms after the 20th week of pregnancy. A severe form of the condition is known as hyperemesis gravidarum and results in weight loss. The cause of morning sickness is unknown but may relate to changing levels of the hormone human chorionic gonadotropin. Some have proposed that morning sickness may be useful from an evolutionary point of view. Diagnosis should only occur after other possible causes have been ruled out. Abdominal pain, fever, or headaches are typically not present in morning sickness. Morning sickness affects about 70–80% of all pregnant women to some extent. About 60% of women experience vomiting. Hyperemesis gravidarum occurs in about 1.6% of pregnancies. Morning sickness can neg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
