For most medieval Europeans, it was a humble brew compared with common southern drinks and cooking ingredients, such as wine, lemons and olive oil.

The importance of vegetables to the common people is illustrated by accounts from 16th-century Germany stating that many peasants ate sauerkraut from three to four times a day. Fruit was popular and could be served fresh, dried, or preserved, and was a common ingredient in many cooked dishes. The fruits of choice in the south were lemons , citrons , bitter oranges the sweet type was not introduced until several hundred years later , pomegranates , quinces , and, of course, grapes.
Farther north, apples , pears , plums , and strawberries were more common. Figs and dates were eaten all over Europe, but remained rather expensive imports in the north. Common and often basic ingredients in many modern European cuisines like potatoes , kidney beans , cacao , vanilla , tomatoes , chili peppers and maize were not available to Europeans until after , after European contact with the Americas, and even then it often took considerable time, sometimes several centuries, for the new foodstuffs to be accepted by society at large.
Milk was an important source of animal protein for those who could not afford meat. It would mostly come from cows, but milk from goats and sheep was also common. Plain fresh milk was not consumed by adults except the poor or sick, and was usually reserved for the very young or elderly. Poor adults would sometimes drink buttermilk or whey or milk that was soured or watered down. On occasion it was used in upper-class kitchens in stews, but it was difficult to keep fresh in bulk and almond milk was generally used in its stead.
Cheese was far more important as a foodstuff, especially for common people, and it has been suggested that it was, during many periods, the chief supplier of animal protein among the lower classes.
There were also whey cheeses , like ricotta , made from by-products of the production of harder cheeses. Cheese was used in cooking for pies and soups, the latter being common fare in German-speaking areas.
Butter , another important dairy product, was in popular use in the regions of Northern Europe that specialized in cattle production in the latter half of the Middle Ages, the Low Countries and Southern Scandinavia. While most other regions used oil or lard as cooking fats, butter was the dominant cooking medium in these areas. Its production also allowed for a lucrative butter export from the 12th century onward. While all forms of wild game were popular among those who could obtain it, most meat came from domestic animals.
Domestic working animals that were no longer able to work were slaughtered but not particularly appetizing and therefore were less valued as meat. Beef was not as common as today because raising cattle was labor-intensive, requiring pastures and feed, and oxen and cows were much more valuable as draught animals and for producing milk.
Mutton and lamb were fairly common, especially in areas with a sizeable wool industry, as was veal. Domestic pigs often ran freely even in towns and could be fed on just about any organic waste, and suckling pig was a sought-after delicacy.
Just about every part of the pig was eaten, including ears, snout, tail, tongue , and womb. Intestines, bladder and stomach could be used as casings for sausage or even illusion food such as giant eggs.
Among the meats that today are rare or even considered inappropriate for human consumption are the hedgehog and porcupine , occasionally mentioned in late medieval recipe collections. In England, they were deliberately introduced by the 13th century and their colonies were carefully protected. They were of particular value for monasteries, because newborn rabbits were allegedly declared fish or, at least, not-meat by the church and therefore they could be eaten during Lent.
A wide range of birds were eaten, including swans , peafowl , quail , partridge , storks , cranes , larks , linnets and other songbirds that could be trapped in nets, and just about any other wild bird that could be hunted. Swans and peafowl were domesticated to some extent, but were only eaten by the social elite, and more praised for their fine appearance as stunning entertainment dishes, entremets , than for their meat. As today, geese and ducks had been domesticated but were not as popular as the chicken , the fowl equivalent of the pig.
But at the Fourth Council of the Lateran , Pope Innocent III explicitly prohibited the eating of barnacle geese during Lent, arguing that they lived and fed like ducks and so were of the same nature as other birds.
Meats were more expensive than plant foods. Though rich in protein , the calorie -to-weight ratio of meat was less than that of plant food. Meat could be up to four times as expensive as bread. Fish was up to 16 times as costly, and was expensive even for coastal populations. This meant that fasts could mean an especially meager diet for those who could not afford alternatives to meat and animal products like milk and eggs.
It was only after the Black Death had eradicated up to half of the European population that meat became more common even for poorer people. The drastic reduction in many populated areas resulted in a labor shortage, meaning that wages dramatically increased. It also left vast areas of farmland untended, making them available for pasture and putting more meat on the market.
Although less prestigious than other animal meats, and often seen as merely an alternative to meat on fast days, seafood was the mainstay of many coastal populations. Also included were the beaver , due to its scaly tail and considerable time spent in water, and barnacle geese , due to the belief that they developed underwater in the form of barnacles.
The Holy Roman Emperor Frederick II examined barnacles and noted no evidence of any bird-like embryo in them, and the secretary of Leo of Rozmital wrote a very skeptical account of his reaction to being served barnacle goose at a fish-day dinner in Especially important was the fishing and trade in herring and cod in the Atlantic and the Baltic Sea.
The herring was of unprecedented significance to the economy of much of Northern Europe, and it was one of the most common commodities traded by the Hanseatic League , a powerful north German alliance of trading guilds. Kippers made from herring caught in the North Sea could be found in markets as far away as Constantinople.
Stockfish , cod that was split down the middle, fixed to a pole and dried, was very common, though preparation could be time-consuming, and meant beating the dried fish with a mallet before soaking it in water. A wide range of mollusks including oysters , mussels and scallops were eaten by coastal and river-dwelling populations, and freshwater crayfish were seen as a desirable alternative to meat during fish days.
Compared to meat, fish was much more expensive for inland populations, especially in Central Europe, and therefore not an option for most. Freshwater fish such as pike , carp , bream , perch , lamprey and trout were common. While in modern times, water is often drunk with a meal, in the Middle Ages, however, concerns over purity, medical recommendations and its low prestige value made it less favored, and alcoholic beverages were preferred. They were seen as more nutritious and beneficial to digestion than water, with the invaluable bonus of being less prone to putrefaction due to the alcohol content.
Wine was consumed on a daily basis in most of France and all over the Western Mediterranean wherever grapes were cultivated. Further north it remained the preferred drink of the bourgeoisie and the nobility who could afford it, and far less common among peasants and workers.
The drink of commoners in the northern parts of the continent was primarily beer or ale. Juices , as well as wines, of a multitude of fruits and berries had been known at least since Roman antiquity and were still consumed in the Middle Ages: Medieval drinks that have survived to this day include prunellé from wild plums modern-day slivovitz , mulberry gin and blackberry wine. Many variants of mead have been found in medieval recipes, with or without alcoholic content.
However, the honey -based drink became less common as a table beverage towards the end of the period and was eventually relegated to medicinal use. This is partially true since mead bore great symbolic value at important occasions. When agreeing on treaties and other important affairs of state, mead was often presented as a ceremonial gift. It was also common at weddings and baptismal parties, though in limited quantity due to its high price.
In medieval Poland , mead had a status equivalent to that of imported luxuries, such as spices and wines. Plain milk was not consumed by adults except the poor or sick, being reserved for the very young or elderly, and then usually as buttermilk or whey. Fresh milk was overall less common than other dairy products because of the lack of technology to keep it from spoiling.
However, neither of these non-alcoholic social drinks were consumed in Europe before the late 16th and early 17th century. Wine was commonly drunk and was also regarded as the most prestigious and healthy choice.
According to Galen 's dietetics it was considered hot and dry but these qualities were moderated when wine was watered down. Unlike water or beer, which were considered cold and moist, consumption of wine in moderation especially red wine was, among other things, believed to aid digestion, generate good blood and brighten the mood. The first pressing was made into the finest and most expensive wines which were reserved for the upper classes. The second and third pressings were subsequently of lower quality and alcohol content.
Common folk usually had to settle for a cheap white or rosé from a second or even third pressing, meaning that it could be consumed in quite generous amounts without leading to heavy intoxication. For the poorest or the most pious , watered-down vinegar similar to Ancient Roman posca would often be the only available choice. The aging of high quality red wine required specialized knowledge as well as expensive storage and equipment, and resulted in an even more expensive end product.
Judging from the advice given in many medieval documents on how to salvage wine that bore signs of going bad, preservation must have been a widespread problem. Even if vinegar was a common ingredient, there was only so much of it that could be used.
In the 14th century cookbook Le Viandier there are several methods for salvaging spoiling wine; making sure that the wine barrels are always topped up or adding a mixture of dried and boiled white grape seeds with the ash of dried and burnt lees of white wine were both effective bactericides , even if the chemical processes were not understood at the time.
Wine was believed to act as a kind of vaporizer and conduit of other foodstuffs to every part of the body, and the addition of fragrant and exotic spices would make it even more wholesome. Spiced wines were usually made by mixing an ordinary red wine with an assortment of spices such as ginger , cardamom , pepper , grains of paradise , nutmeg , cloves and sugar. These would be contained in small bags which were either steeped in wine or had liquid poured over them to produce hypocras and claré.
By the 14th century, bagged spice mixes could be bought ready-made from spice merchants. While wine was the most common table beverage in much of Europe, this was not the case in the northern regions where grapes were not cultivated.
Those who could afford it drank imported wine, but even for nobility in these areas it was common to drink beer or ale , particularly towards the end of the Middle Ages. In England , the Low Countries , northern Germany , Poland and Scandinavia , beer was consumed on a daily basis by people of all social classes and age groups.
For most medieval Europeans, it was a humble brew compared with common southern drinks and cooking ingredients, such as wine, lemons and olive oil. Even comparatively exotic products like camel 's milk and gazelle meat generally received more positive attention in medical texts. Beer was just an acceptable alternative and was assigned various negative qualities. In , the Sienese physician Aldobrandino described beer in the following way:.
But from whichever it is made, whether from oats, barley or wheat, it harms the head and the stomach, it causes bad breath and ruins the teeth , it fills the stomach with bad fumes, and as a result anyone who drinks it along with wine becomes drunk quickly; but it does have the property of facilitating urination and makes one's flesh white and smooth.
The intoxicating effect of beer was believed to last longer than that of wine, but it was also admitted that it did not create the "false thirst" associated with wine. Though less prominent than in the north, beer was consumed in northern France and the Italian mainland.
Perhaps as a consequence of the Norman conquest and the travelling of nobles between France and England, one French variant described in the 14th century cookbook Le Menagier de Paris was called godale most likely a direct borrowing from the English "good ale" and was made from barley and spelt , but without hops.
In England there were also the variants poset ale , made from hot milk and cold ale, and brakot or braggot , a spiced ale prepared much like hypocras.
That hops could be used for flavoring beer had been known at least since Carolingian times, but was adopted gradually due to difficulties in establishing the appropriate proportions. Before the widespread use of hops, gruit , a mix of various herbs , had been used. Gruit had the same preserving properties as hops, though less reliable depending on what herbs were in it, and the end result was much more variable. Another flavoring method was to increase the alcohol content, but this was more expensive and lent the beer the undesired characteristic of being a quick and heavy intoxicant.
Hops may have been widely used in England in the tenth century; they were grown in Austria by and in Finland by , and possibly much earlier. Before hops became popular as an ingredient, it was difficult to preserve this beverage for any time, and so, it was mostly consumed fresh. Quantities of beer consumed by medieval residents of Europe, as recorded in contemporary literature, far exceed intakes in the modern world. For example, sailors in 16th century England and Denmark received a ration of 1 imperial gallon 4.
Polish peasants consumed up to 3 litres 0. In the Early Middle Ages beer was primarily brewed in monasteries , and on a smaller scale in individual households. By the High Middle Ages breweries in the fledgling medieval towns of northern Germany began to take over production.
Though most of the breweries were small family businesses that employed at most eight to ten people, regular production allowed for investment in better equipment and increased experimentation with new recipes and brewing techniques. These operations later spread to the Netherlands in the 14th century, then to Flanders and Brabant , and reached England by the 15th century.
Hopped beer became very popular in the last decades of the Late Middle Ages. When perfected as an ingredient, hops could make beer keep for six months or more, and facilitated extensive exports. In turn, ale or beer was classified into "strong" and "small", the latter less intoxicating, regarded as a drink of temperate people, and suitable for consumption by children. As late as , John Locke stated that the only drink he considered suitable for children of all ages was small beer, while criticizing the apparently common practice among Englishmen of the time to give their children wine and strong alcohol.
By modern standards, the brewing process was relatively inefficient, but capable of producing quite strong alcohol when that was desired. One recent attempt to recreate medieval English "strong ale" using recipes and techniques of the era albeit with the use of modern yeast strains yielded a strongly alcoholic brew with original gravity of 1.
The ancient Greeks and Romans knew of the technique of distillation , but it was not practiced on a major scale in Europe until some time around the 12th century, when Arabic innovations in the field combined with water-cooled glass alembics were introduced. Distillation was believed by medieval scholars to produce the essence of the liquid being purified, and the term aqua vitae "water of life" was used as a generic term for all kinds of distillates.
Alcoholic distillates were also occasionally used to create dazzling, fire-breathing entremets a type of entertainment dish after a course by soaking a piece of cotton in spirits. It would then be placed in the mouth of the stuffed, cooked and occasionally redressed animals, and lit just before presenting the creation. Aqua vitae in its alcoholic forms was highly praised by medieval physicians.
In Arnaldus of Villanova wrote that "[i]t prolongs good health, dissipates superfluous humours, reanimates the heart and maintains youth. By the 13th century, Hausbrand literally "home-burnt" from gebrannter wein, brandwein ; "burnt [distilled] wine" was commonplace, marking the origin of brandy.
Towards the end of the Late Middle Ages, the consumption of spirits became so ingrained even among the general population that restrictions on sales and production began to appear in the late 15th century. In the city of Nuremberg issued restrictions on the selling of aquavit on Sundays and official holidays. Spices were among the most luxurious products available in the Middle Ages, the most common being black pepper , cinnamon and the cheaper alternative cassia , cumin , nutmeg , ginger and cloves.
They all had to be imported from plantations in Asia and Africa , which made them extremely expensive, and gave them social cachet such that pepper for example was hoarded, traded and conspicuously donated in the manner of gold bullion.
The value of these goods was the equivalent of a yearly supply of grain for 1. Sugar , unlike today, was considered to be a type of spice due to its high cost and humoral qualities. Even when a dish was dominated by a single flavor it was usually combined with another to produce a compound taste, for example parsley and cloves or pepper and ginger.
Common herbs such as sage , mustard , and parsley were grown and used in cooking all over Europe, as were caraway , mint , dill and fennel. Many of these plants grew throughout all of Europe or were cultivated in gardens, and were a cheaper alternative to exotic spices. Mustard was particularly popular with meat products and was described by Hildegard of Bingen — as poor man's food.
While locally grown herbs were less prestigious than spices, they were still used in upper-class food, but were then usually less prominent or included merely as coloring. Anise was used to flavor fish and chicken dishes, and its seeds were served as sugar-coated comfits.
Surviving medieval recipes frequently call for flavoring with a number of sour, tart liquids. Wine, verjuice the juice of unripe grapes or fruits vinegar and the juices of various fruits, especially those with tart flavors, were almost universal and a hallmark of late medieval cooking. In combination with sweeteners and spices, it produced a distinctive "pungeant, fruity" flavor.
Equally common, and used to complement the tanginess of these ingredients, were sweet almonds. They were used in a variety of ways: This last type of non-dairy milk product is probably the single most common ingredient in late medieval cooking and blended the aroma of spices and sour liquids with a mild taste and creamy texture.
Salt was ubiquitous and indispensable in medieval cooking. Salting and drying was the most common form of food preservation and meant that fish and meat in particular were often heavily salted. Many medieval recipes specifically warn against oversalting and there were recommendations for soaking certain products in water to get rid of excess salt.
The richer the host, and the more prestigious the guest, the more elaborate would be the container in which it was served and the higher the quality and price of the salt. Wealthy guests were seated " above the salt ", while others sat "below the salt", where salt cellars were made of pewter, precious metals or other fine materials, often intricately decorated.
The rank of a diner also decided how finely ground and white the salt was. Salt for cooking, preservation or for use by common people was coarser; sea salt, or "bay salt", in particular, had more impurities, and was described in colors ranging from black to green.
Expensive salt, on the other hand, looked like the standard commercial salt common today. The AAS that have been used most commonly in medicine are testosterone and its many esters but most typically testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ,  nandrolone esters typically nandrolone decanoate and nandrolone phenylpropionate , stanozolol , and metandienone methandrostenolone.
Designer steroids are AAS that have not been approved and marketed for medical use but have been distributed through the black market. There are four common forms in which AAS are administered: Oral administration is the most convenient. Testosterone administered by mouth is rapidly absorbed, but it is largely converted to inactive metabolites, and only about one-sixth is available in active form. This modification reduces the liver's ability to break down these compounds before they reach the systemic circulation.
Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate and thus injection schedule varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks.
A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism clot in the bloodstream.
Transdermal patches adhesive patches placed on the skin may also be used to deliver a steady dose through the skin and into the bloodstream. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses.
Injection is the most common method used by individuals administering AAS for non-medical purposes. The traditional routes of administration do not have differential effects on the efficacy of the drug. Studies indicate that the anabolic properties of AAS are relatively similar despite the differences in pharmacokinetic principles such as first-pass metabolism.
However, the orally available forms of AAS may cause liver damage in high doses. Known possible side effects of AAS include: Depending on the length of drug abuse, there is a chance that the immune system can be damaged. Most of these side-effects are dose-dependent, the most common being elevated blood pressure , especially in those with pre-existing hypertension. AAS have been shown to alter fasting blood sugar and glucose tolerance tests. A number of severe side effects can occur if adolescents use AAS.
For example, AAS may prematurely stop the lengthening of bones premature epiphyseal fusion through increased levels of estrogen metabolites , resulting in stunted growth. Other effects include, but are not limited to, accelerated bone maturation , increased frequency and duration of erections, and premature sexual development.
AAS use in adolescence is also correlated with poorer attitudes related to health. Probably carcinogenic to humans. Other side-effects can include alterations in the structure of the heart , such as enlargement and thickening of the left ventricle , which impairs its contraction and relaxation , and therefore reducing ejected blood volume. AAS use can cause harmful changes in cholesterol levels: AAS use in adolescents quickens bone maturation and may reduce adult height in high doses. There are also sex-specific side effects of AAS.
Development of breast tissue in males, a condition called gynecomastia which is usually caused by high levels of circulating estradiol , may arise because of increased conversion of testosterone to estradiol by the enzyme aromatase. This side-effect is temporary; the size of the testicles usually returns to normal within a few weeks of discontinuing AAS use as normal production of sperm resumes.
Female-specific side effects include increases in body hair , permanent deepening of the voice, enlarged clitoris , and temporary decreases in menstrual cycles.
Alteration of fertility and ovarian cysts can also occur in females. Kidney tests revealed that nine of the ten steroid users developed a condition called focal segmental glomerulosclerosis , a type of scarring within the kidneys. The kidney damage in the bodybuilders has similarities to that seen in morbidly obese patients, but appears to be even more severe. High doses of oral AAS compounds can cause liver damage.
A review in CNS Drugs determined that "significant psychiatric symptoms including aggression and violence, mania , and less frequently psychosis and suicide have been associated with steroid abuse. Long-term steroid abusers may develop symptoms of dependence and withdrawal on discontinuation of AAS".
Recreational AAS use appears to be associated with a range of potentially prolonged psychiatric effects, including dependence syndromes, mood disorders , and progression to other forms of substance abuse, but the prevalence and severity of these various effects remains poorly understood.
Large-scale long-term studies of psychiatric effects on AAS users are not currently available. DSM-IV lists General diagnostic criteria for a personality disorder guideline that "The pattern must not be better accounted for as a manifestation of another mental disorder, or to the direct physiological effects of a substance e.
As a result, AAS users may get misdiagnosed by a psychiatrist not told about their habit. Affective disorders have long been recognised as a complication of AAS use. From the mids onward, the media reported "roid rage" as a side effect of AAS. A review determined that some, but not all, randomized controlled studies have found that AAS use correlates with hypomania and increased aggressiveness, but pointed out that attempts to determine whether AAS use triggers violent behavior have failed, primarily because of high rates of non-participation.
Compared with individuals that did not use steroids, young adult males that used AAS reported greater involvement in violent behaviors even after controlling for the effects of key demographic variables, previous violent behavior, and polydrug use.
The drug response was highly variable. The mechanism of these variable reactions could not be explained by demographic, psychological, laboratory, or physiological measures. A study of two pairs of identical twins, in which one twin used AAS and the other did not, found that in both cases the steroid-using twin exhibited high levels of aggressiveness, hostility, anxiety, and paranoid ideation not found in the "control" twin.
The relationship between AAS use and depression is inconclusive. There have been anecdotal reports of depression and suicide in teenage steroid users,  but little systematic evidence. A review found that AAS may both relieve and cause depression, and that cessation or diminished use of AAS may also result in depression, but called for additional studies due to disparate data.
Androgens such as testosterone , androstenedione and dihydrotestosterone are required for the development of organs in the male reproductive system , including the seminal vesicles , epididymis , vas deferens , penis and prostate. The pharmacodynamics of AAS are unlike peptide hormones.
However, as fat-soluble hormones, AAS are membrane-permeable and influence the nucleus of cells by direct action. The pharmacodynamic action of AAS begin when the exogenous hormone penetrates the membrane of the target cell and binds to an androgen receptor AR located in the cytoplasm of that cell.
From there, the compound hormone-receptor diffuses into the nucleus, where it either alters the expression of genes  or activates processes that send signals to other parts of the cell. The effect of AAS on muscle mass is caused in at least two ways: It has been hypothesized that this reduction in muscle breakdown may occur through AAS inhibiting the action of other steroid hormones called glucocorticoids that promote the breakdown of muscles.
As their name suggests, AAS have two different, but overlapping, types of effects: Some examples of the anabolic effects of these hormones are increased protein synthesis from amino acids , increased appetite, increased bone remodeling and growth, and stimulation of bone marrow , which increases the production of red blood cells. Through a number of mechanisms AAS stimulate the formation of muscle cells and hence cause an increase in the size of skeletal muscles , leading to increased strength.
The androgenic effects of AAS are numerous. Depending on the length of use, the side effects of the steroid can be irreversible.
Processes affected include pubertal growth, sebaceous gland oil production, and sexuality especially in fetal development. Some examples of virilizing effects are growth of the clitoris in females and the penis in male children the adult penis size does not change due to steroids [ medical citation needed ] , increased vocal cord size, increased libido , suppression of natural sex hormones , and impaired production of sperm.
Men may develop an enlargement of breast tissue, known as gynecomastia, testicular atrophy, and a reduced sperm count. Compounds with a high ratio of androgenic to an anabolic effects are the drug of choice in androgen-replacement therapy e. This disassociation is less marked in humans, where all AAS have significant androgenic effects. A commonly used protocol for determining the androgenic: The VP weight is an indicator of the androgenic effect, while the LA weight is an indicator of the anabolic effect.
Two or more batches of rats are castrated and given no treatment and respectively some AAS of interest. Animal studies also found that fat mass was reduced, but most studies in humans failed to elucidate significant fat mass decrements.
The effects on lean body mass have been shown to be dose-dependent. Both muscle hypertrophy and the formation of new muscle fibers have been observed. The hydration of lean mass remains unaffected by AAS use, although small increments of blood volume cannot be ruled out. The upper region of the body thorax, neck, shoulders, and upper arm seems to be more susceptible for AAS than other body regions because of predominance of ARs in the upper body.
After drug withdrawal, the effects fade away slowly, but may persist for more than 6—12 weeks after cessation of AAS use. Overall, the exercise where the most significant improvements were observed is the bench press. The measurement of the dissociation between anabolic and androgenic effects among AAS is based largely on a simple although arguably unsophisticated and outdated model involving rat tissue bioassays.
The intracellular metabolism theory explains how and why remarkable dissociation between anabolic and androgenic effects can occur despite the fact that these effects are mediated through the same signaling receptor, and of course why dissociation is invariably incomplete. An animal study found that two different kinds of androgen response elements could differentially respond to testosterone and DHT upon activation of the AR.
Changes in endogenous testosterone levels may also contribute to differences in myotrophic—androgenic ratio between testosterone and synthetic AAS. Testosterone can be metabolized by aromatase into estradiol , and many other AAS can be metabolized into their corresponding estrogenic metabolites as well. The major effect of estrogenicity is gynecomastia woman-like breasts. AAS are androstane or estrane steroids. As well as others such as 1-dehydrogenation e. The most commonly employed human physiological specimen for detecting AAS usage is urine, although both blood and hair have been investigated for this purpose.
The AAS, whether of endogenous or exogenous origin, are subject to extensive hepatic biotransformation by a variety of enzymatic pathways. The primary urinary metabolites may be detectable for up to 30 days after the last use, depending on the specific agent, dose and route of administration. A number of the drugs have common metabolic pathways, and their excretion profiles may overlap those of the endogenous steroids, making interpretation of testing results a very significant challenge to the analytical chemist.
Methods for detection of the substances or their excretion products in urine specimens usually involve gas chromatography—mass spectrometry or liquid chromatography-mass spectrometry. The use of gonadal steroids pre-dates their identification and isolation. Medical use of testicle extract began in the late 19th century while its effects on strength were still being studied. In the s, it was already known that the testes contain a more powerful androgen than androstenone , and three groups of scientists, funded by competing pharmaceutical companies in the Netherlands, Germany, and Switzerland, raced to isolate it.
The chemical synthesis of testosterone was achieved in August that year, when Butenandt and G. Wettstein, announced a patent application in a paper "On the Artificial Preparation of the Testicular Hormone Testosterone Androstenoneol. The Zone diet is mostly meat, fruits, and vegetables.
You eat three meals per day plus two Zone protein-powder snacks. A study of people in the Journal of American Medical Association found the Zone diet helped people achieve modest weight loss after one year, comparable with those on the Atkins , Weight Watchers and Ornish diets, and improved cardiac risk factors.
Premium-priced Jenny Craig lets you order its heart-healthy, nutritionally balanced packaged food by phone and pick it up at a Jenny Craig center or have it delivered through Jenny Direct.
You eat three Jenny Craig meals plus a snack per day, and supplement with fruit, vegetables and dairy. Once a week, you get a weigh-in and pep talk with a consultant - who is not a dietician and who earns commissions from selling you products.
There's also round-the-clock phone support. Jenny Craig has a good track record for short-term weight loss up to one year. In a UC San Diego clinical trial of dieters funded by Jenny Craig , Jenny Craig clients lost 11 percent of their initial weight after 12 months, compared with 3 percent weight loss by those who were dieting on their own. The "doctor-designed" Bistro M. The price is a cut above the competition, too. The plan tries to help you avoid a weight-loss stall out by varying the daily calorie intake between 1, and 1, By eating a little more some days and a little less on others, you'll supposedly prevent your body from becoming used to the same number of calories every day.
While no university studies support the theory that varying caloric intake aids weight loss, the high quality of the food and the relatively large portion sizes have been praised by Health magazine, Dr. Phil and The New York Times. Some plan users have complained of a lack of choices and menu flexibility compared to other plans, but a company spokesman says they offer more than entrees and can make substitutions to accommodate allergies and food preferences. It's a reasonable price for well-made food with slightly faster average weight loss than with Jenny Craig.
This meal-delivery service, endorsed by Marie Osmond and Dan Marino, emphasizes foods with a low glycemic index. The underlying premise is that controlling blood sugar levels leads to weight loss. The heat-and-eat prepared meals and snacks contain roughly 55 percent "good" carbs, 25 percent protein, and 20 percent fats; like Jenny Craig, you add fruits, vegetables and dairy. Support is available through phone counseling and online chat rooms. There's plenty of research showing that following a diet of 1, to 1, calories a day, such as Nutrisystem, can cause weight loss.
For example, a study by the Obesity Research Center at St. Luke's Roosevelt Hospital in New York found that postmenopausal women who followed a 1,calorie plan for 16 weeks lost an average of 21 pounds. For a meal-delivery diet system, Nutrisystem is more economical than Jenny Craig. Although today's program is not as stringent as the original liquid fast Medifast launched decades ago, the low-fat, relatively low-carb plan is designed to bring about rapid weight loss by coaxing your body into a "fat-burning state" known as ketosis.
The 70 meal replacement choices include shakes, bars, soups, pudding, oatmeal, chili, pretzel sticks, cheese puffs, and scrambled eggs.
If you can stick with it, a diet of 1, calories a day can certainly induce rapid weight loss. A common concern with such low-calorie diets is that you'll quickly regain the weight, but in a small clinical trial recently published in the journal Experimental Biology , after 10 months, only about one in five people regained all the weight they had lost.
Choose this more extreme plan only if quick weight loss is your priority. Within hours of posting a seven-second video of their son learning to walk, Whitney and Adam Dinkel were flooded with messages.
