The issue of '''wine and health''' is a topic of considerable discussion and research. Wine has a long [[history (wine)|history]] of use as an [[History of medicine|early form of medication]], being recommended variously as a safe alternative to [[drinking water]], an [[antiseptic]] for treating wounds and a [[Digestion|digestive aid]], as well as a cure for a wide range of ailments from [[lethargy]] and [[diarrhea]] to easing the pain of [[child birth]].<ref name="Miscellany"> G.

==Historical role of wine in medicine==
{{See also|History of medicine}}
Early medicine was intimately tied with [[religion]] and the [[supernatural]], with early practitioners often being [[priest]]s and [[magician (paranormal)|magician]]s. Wine's close association with made it a logical tool for these early medical practices. Tablets from Sumerian culture and papyri from Ancient Egypt dating to 2200 BC include recipes for wine based medicines, making wine the oldest documented man made medicine.<ref name="Oxford pg 433"/>

===Early history===
[[File:Hippocrates Light.JPG|left|thumb|Hippocrates, the father of modern medicine, prescribed wine for a variety of ailments include lethargy and diarrhea.]]
When the [[ancient Greeks]] introduced a more systematized approach to medicine, wine still retained its prominent role. The Greek physician [[Hippocrates]] recommended wine as a part of a healthy [[diet]] and advocated it uses a [[disinfectant]] for wounds as well as a medium to mix other drugs in for easier consumption by the patient. He also prescribed wine as a cure for various ailments ranging from diarrhea to lethargy to pain during childbirth.<ref name="Oxford pg 433"/> The medical practices of the [[ancient Romans]] used wine in a similar fashion. In his 1st century work ''[[De Medicina]]'', the Roman encyclopedist [[Aulus Cornelius Celsus]] detailed a long list of [[Ancient Greek (wine)|Greek]] and [[Roman wine]] that were used in medical practices. While treating [[gladiators]] in [[Asia Minor]], the Roman physician [[Galen]] would use wine as a disinfectant for all types of wounds, even soaking the exposed [[bowels]] and [[stomach]] content before returning them to the body. During his four years tending to the gladiators only five deaths occurred, compared to sixty deaths under the watch of the physician before him.<ref name="nutton73">{{Cite journal| issn = 00098388| volume = 23| issue = 1| pages = 169| last = Nutton| first = Vivian| title = The Chronology of Galen's Early Career| journal = The Classical Quarterly| series = 2| accessdate = July 21st, 2009 | date = 1973-05 | url = http://links.jstor.org/sici?sici=0009-8388%28197305%292%3A23%3A1%3C158%3ATCOGEC%3E2.0.CO%3B2-S}}</ref>

Religion still played a significant role in promoting wine's use for health benefit. The [[Talmud]] noted ''"Wine is the foremost of all medicines: wherever wine is lacking, medicines become necessary."''. In his [[first epistle to Timothy]], [[Paul the Apostle]] recommended that his [[Timothy|young colleague]] drink a little wine every now and then for the benefit of his stomach and digestion. While the [[Islamic]] [[Koran]] contained [[Islamic_dietary_laws#Alcohol|restrictions on all alcohol]], Islamic doctors such as [[Avicenna]] in the 11th century AD noted that wine was an efficient digestive aid but because of Islamic laws were limited only in using it as a disinfectant while dressing wounds. [[Catholic (church)|Catholic]] [[monasteries]] during the [[Middle Ages]] would also regularly use wine for various medical treatments.<ref name="Oxford pg 433"/> So closely tied was the role of wine and medicine that the first printed book on the subject of wine was written by a physician, [[Arnaldus de Villa Nova]], in the 14th century which included lengthy writings on wine's treatment of various medical illnesses such [[dementia]] and [[sinusitis|sinus]] troubles.<ref> Hugh Johnson, ''Vintage: The Story of Wine'' pg 126.

===Changing views highlight the risks of consumption===
The [[history of wine]] includes use as an [[History of medicine|early form of medication]], being recommended variously as a safe alternative to [[drinking water]], an [[antiseptic]] for treating wounds, a [[Digestion|digestive aid]], and as a cure for a wide range of ailments including [[lethargy]], [[diarrhea]], and pain from [[child birth]].<ref name="Miscellany">{{cite book | vauthors = Harding G|title=A Wine Miscellany | url = https://archive.org/details/winemiscellanyja00hard| url-access = registration|pages=66–70, 90 & 108 |publisher=Clarkson Potter |location=New York |year=2005 |isbn=978-0-307-34635-3}}</ref> [[Ancient Egypt]]ian [[papyri]] and [[Sumer]]ian tablets dating back to 2200 BC detail the medicinal role of wine, making it the world's oldest documented human-made medicine.<ref name="Robinson_2006">{{cite book |veditors=Robinson J |title=The Oxford Companion to Wine |edition=3rd |publisher=Oxford University Press |year=2006 |isbn=978-0-19-860990-2 |url=https://archive.org/details/oxfordcompaniont00janc }}</ref>{{rp|433}} Wine continued to play a major role in medicine until the late 19th and early 20th century, when changing opinions and medical research on alcohol and [[alcoholism]] cast doubt on its role as part of a healthy lifestyle.
The lack of safe [[drinking water]] for much of history may have been one reason for wine's popularity in medicine. Wine was still being used to sterilize water as late as the 1892 [[cholera]] epidemic of [[Hamburg]] in order to control the disease's spread. However the late 19th century and early 20th century ushered in a period of changing views on the role of [[alcohol]] (and by extension) wine in health and society. The [[Temperance movement]] started to gain steam by touting the ills of [[alcoholism]], which was eventually defined by the medical establishment as [[Disease theory of alcoholism|a disease]]. Studies regarding the [[Long-term effects of alcohol|long]] and [[short-term effects of alcohol]] caused many in the medical community to reconsider wine's role in medicine and diet.<ref name="Oxford pg 433"/> Public opinion against consumption of alcohol in all forms lead to [[Prohibition in the United States]] and other countries. In some areas wine was able to maintain a limited role, such as an exemption in the United States for "[[therapeutic]] wines" that were sold legally in drug stores. These wines were marketed for their medicinal benefits but some wineries used this measure as a loophole to sell large quantities of wine for normal consumption. In response, the United State government issued a mandate requiring producers to include an [[emetic]] additive that would induce vomiting above the consumption of a certain dosage level.<ref name="Miscellany"/>


==Moderate consumption==
Throughout the mid to early 20th century, health advocates touted the risk of alcoholic consumption and the role it played in a variety of ailments such as [[blood disorders]], [[high blood pressure]], [[cancer]], [[infertility]], [[liver damage]], [[muscle atrophy]], [[psoriasis]], [[skin infections]], [[strokes]], and long term [[brain damage]]. Studies showed a connection between alcohol consumption of pregnant mothers and an increased risk of [[mental retardation]] and physical abnormalities for their fetus in what became known as [[fetal alcohol syndrome]]. The use of [[warning labels]] on alcohol products began in several countries warning of these dangers.<ref name="Oxford pg 341-342"/>

The view of consuming wine in moderation has a history recorded as early as the Greek poet [[Eubulus (poet)|Eubulus]] (360 BC) who believed that three bowls ([[Kylix (drinking cup)|kylix]]) were the ideal amount of wine to consume. The number of three bowls for moderation is a common theme throughout Greek writing; today the standard 750 ml [[wine bottle]] contains roughly the volume of three kylix cups (250&nbsp;ml or 8&nbsp;fl&nbsp;oz each).<ref name="Johnson pg 35-46">{{cite book | vauthors = Johnson H | title = Vintage: The Story of Wine | pages = [https://archive.org/details/vintagestoryofwi00john/page/35 35–46] | publisher = Simon and Schuster | date = 1989 | isbn = 978-0-671-68702-1 | url = https://archive.org/details/vintagestoryofwi00john/page/35 }}</ref> However, the kylix cups would have contained a [[Ancient Greece and wine#Greek wine|diluted wine]], at a 1:2 or 1:3 dilution with water.

===1990s: French Paradox and renewed interest in the benefits of consumption===
[[File:Château Lafite Rothschild and glass.jpg|250px|right|thumb|Despite having a diet that features high fat dairy products such as cheeses, the French have lower rates of heart diseases. One explanation for this "paradox" is the regular consumption of red wine.]]
The 1990s and early 21st century saw a renewed interest in the health benefits of wine, ushered in by increasing research suggesting that moderate wine drinkers have lower mortality rates than heavy or non-drinkers.<ref name="Oxford pg 341-342"/> In November 1991, the U.S. news program ''60 Minutes'' aired a broadcast on the so-called "[[French Paradox]]". Featuring the research work of [[Bordeaux]] scientist [[Serge Renaud]], the broadcast dealt with the seemingly [[paradox]]ical relationship between the high fat/high dairy diets of [[French people]] and the low occurrence of cardiovascular disease among them. The broadcast drew parallels to the American and British diets which also featured high levels of fat and dairy and lead to high numbers of heart disease related deaths among Americans. One of the theories proposed by Renaud in the broadcast was that moderate consumption of red wine was a risk-reducing factor for the French and that wine could have more positive health benefits yet to be studied.<ref>P.

''Semele or Dionysus'', fr. 93.</ref>}}
This changing view of wine can be seen in the evolution of language in the [[U.S. Food and Drug Administration]] [[Dietary Guidelines]]. The 1990 edition of the guidelines contained the blanket statement that ''"wine has no net health benefit"''. By 1995, the wording had been changed to allow moderate consumption with meals providing the individual had no other alcohol related health risk.<ref name="wine pros"/> From a research perspective, scientists began distinguishing alcohol consumption among the different classes of beverages-wine, beer and spirits. This distinction allowed studies to highlight the positive medical benefits of wine apart from just the presence of alcohol. However, wine drinkers tend to share similar lifestyle habitats-such as better diets, more exercise and non-smoking-that can differ from the lifestyles of beer, spirits and non-drinkers which may be a factor in itself for the possible positive health benefits of moderate wine consumption.<ref>P.

It has received a lot of attention in both the [[media]] and medical research community for its potential health benefits. Belonging to a class of compounds known as [[stilbenoid]], resveratrol is also found outside of the ''[[Vitis]]'' [[grapevine]] family in plants such as [[eucalyptus]] and [[peanut]]s. It is part of the defence mechanism in grapevines, used as a [[phytoalexin]] produced in the leaves and berry skins in response to a [[microbial]] attack by fungus or [[grape disease]]. In a controlled setting, this reaction can be artificially induced by exposure to [[ultraviolet radiation]]. The build up of resveratrol slows and sometimes will stop the spreading infection.<ref name="Oxford pg 569"> J.

According to NC State University researchers, Muscadines contain a unique blend of several natural antioxidants that can reduce the risk factors associated with degenerative diseases.

==Heavy metals==
The production and concentration of resveratrol is not equal among all the varieties of [[grape varieties|wine grapes]]. Differences in [[clones (plant)|clones]], [[rootstock]], ''Vitis'' species as well as climate conditions can affect the production of resveratrol. The degree of exposure to greater risk of fungal infection and grape diseases also appear to play a role. The [[Muscadinia]] family of vines, which has adapted over time through exposure to [[North American]] grape diseases such as [[phylloxera]], has some of the highest concentrations of resveratrol among wine grapes. Among the European ''[[Vitis vinifera]]'', grapes derived from the [[Burgundian (wine)|Burgundian]] [[Pinot]] family tend to have substantially higher amounts of resveratrol than grapes derived from the [[Cabernet]] family of [[Bordeaux (wine)|Bordeaux]]. Wine regions with cooler, wetter climates that are more prone to grape disease and fungal attacks (such as [[Oregon (wine)|Oregon]], [[New York (wine)|New York]]) tend to produce grapes with higher concentrations of resveratrol than warmer, dry climates like [[California (wine)|California]] and [[Australia (wine)|Australia]].<ref name="Oxford pg 569"/>
In 2008, researchers from [[Kingston University]] in London discovered red wine<ref>The sample wine was declared to be "a Shiraz from Southeast Australia", although no specific vintage, producer or wine region was stated in the report.</ref> to contain high levels of [[toxic metals]] relative to other beverages in the sample. Although the metal [[ions]], which included [[chromium]], [[copper]], [[iron]], [[manganese]], [[nickel]], [[vanadium]] and [[zinc]], were also present in other plant-based beverages, the sample wine tested significantly higher for all metal ions, especially vanadium.<ref name=hague>{{cite journal | vauthors = Hague T, Petroczi A, Andrews PL, Barker J, Naughton DP | title = Determination of metal ion content of beverages and estimation of target hazard quotients: a comparative study | journal = Chemistry Central Journal | volume = 2 | pages = 13 | date = June 2008 | pmid = 18578877 | pmc = 2443149 | doi = 10.1186/1752-153X-2-13 | doi-access = free }}</ref> Risk assessment was calculated using "[[target hazard quotients]]" (THQ), a method of quantifying health concerns associated with lifetime exposure to chemical pollutants. Developed by the [[Environmental Protection Agency]] in the US and used mainly to examine [[seafood]], a THQ of less than 1 represents no concern while, for example, [[Mercury in fish|mercury level]]s in fish calculated to have THQs of between 1 and 5 would represent cause for concern.<ref>{{cite journal | vauthors = Wang X, Sato T, Xing B, Tao S | title = Health risks of heavy metals to the general public in Tianjin, China via consumption of vegetables and fish | journal = The Science of the Total Environment | volume = 350 | issue = 1–3 | pages = 28–37 | date = November 2005 | pmid = 16227070 | doi = 10.1016/j.scitotenv.2004.09.044 | bibcode = 2005ScTEn.350...28W }}</ref>


The researchers stressed that a single glass of wine would not lead to metal poisoning, pointing out that their THQ calculations were based on the average person drinking one-third of a bottle of wine (250&nbsp;ml) every day between the ages of 18 and 80. However the "combined THQ values" for metal ions in the red wine they analyzed were reported to be as high as 125.<ref name=hague /> A subsequent study by the same university using a [[meta analysis]] of data based on wine samples from a selection of mostly [[Europe]]an countries found equally high levels of vanadium in many red wines, showing combined THQ values in the range of 50 to 200, with some as high as 350.<ref name=naughton>{{cite journal | vauthors = Naughton DP, Petróczi A | title = Heavy metal ions in wines: meta-analysis of target hazard quotients reveal health risks | journal = Chemistry Central Journal | volume = 2 | pages = 22 | date = October 2008 | pmid = 18973648 | pmc = 2628338 | doi = 10.1186/1752-153X-2-22 | doi-access = free }}</ref>
Red wine tends to have a significantly higher concentration of resveratrol than white wine, even though white wine grape varieties produce similar amounts in the vineyards. This is because during [[winemaking]] white wine spends very little if any time in contact with the resveratrol-rich grape skins. This [[maceration (wine)|maceration]] period not only gives red wine its color but allows for the extraction of phenolic compounds such as resveratrol into the resulting wine. Other winemaking techniques, such as the use of certain strains of [[yeast]] during [[fermentation (wine)|fermentation]] or [[lactic acid bacteria]] during [[malolactic fermentation]], can have an influence on the amount of resveratrol left in the resulting wines. Similarly the use of certain [[fining agents]] during the [[clarification and stabilization of wine]] can strip the wine of some resveratrol molecules.<ref name="Oxford pg 569"/>


The findings sparked immediate controversy due to several issues: the study's reliance on [[secondary data]]; the assumption that all wines contributing to that data were representative of the countries stated; and the grouping together of poorly understood high-concentration ions, such as vanadium, with relatively low-level, common ions such as copper and manganese. Some publications pointed out that the lack of identifiable wines and grape varieties, specific producers or even wine regions, provided only misleading generalizations that should not be relied upon in choosing wines.<ref name=ws>[http://www.winespectator.com/webfeature/show/id/Study-of-Wines-Heavy-Metal-Hazard-Raises-Doubts-Among-Other-Experts_4444 Study of Wine's Heavy Metal Hazard Raises Doubts Among Other Experts] Wine Spectator, November 2008</ref><ref name=nhs>[http://www.nhs.uk/news/2008/10October/Pages/Metalsinwine.aspx Metal in wine] {{Webarchive|url=https://web.archive.org/web/20121007104255/http://www.nhs.uk/news/2008/10October/Pages/Metalsinwine.aspx |date=2012-10-07 }}, UK NHS news bulletin, October 2008</ref>
The prominence of resveratrol in the news and its association with positive health benefits has encouraged some wineries to highlight it in their marketing. In the early 21st century, the Oregon producer [[Willamette Valley Vineyards]] sought approval from the [[Alcohol and Tobacco Tax and Trade Bureau]] (TTB) to state on their [[wine labels]] the resveratrol levels of their wines which ranged from 19 to 71 molecules per liter (higher than the average 10 molecules per liter in most red wines). The TTB gave preliminary approval to the winery, making it the first to use such information on its labels.<ref name="Miscellany"/> While resveratrol is the most widely publicized, there are other components in wine that have been the focus of medical research into potential health benefits. These include the compounds [[catechin]] and [[quercetin]].<ref name="Oxford pg 569"/>


In a news bulletin following the widespread reporting of the findings, the UK's [[National Health Service]] (NHS) were also concerned that "the way the researchers added together hazards from different metals to produce a final score for individual wines may not be particularly meaningful".<ref name=nhs /> Commentators in the US questioned the relevance of seafood-based THQ assessments to [[agriculture|agricultural]] produce, with the [[Alcohol and Tobacco Tax and Trade Bureau|TTB]], responsible for testing imports for metal ion contamination, have not detected an increased risk. George Solas, quality assessor for the Canadian [[Liquor Control Board of Ontario]] (LCBO) claimed that the levels of heavy metal contamination reported were within the permitted levels for drinking water in tested [[reservoir]]s.<ref name=ws />
==Wine's effect on the body==


Whereas the NHS also described calls for improved [[wine label]]ing as an "extreme response" to research which provided "few solid answers", they acknowledged the authors call for further research to investigate wine production, including the influence that grape variety, soil type, geographical region, [[insecticide]]s, containment vessels and seasonal variations may have on metal ion uptake.<ref name=nhs />
===Bones===
Heavy alcohol consumption has been shown to have a damaging effect on the cellular process that create [[bone tissue]]. Long term alcoholic consumption at high levels increases the frequency of [[fracture]]s.<ref name="Oxford pg 341-342"/> Studies from St. Thomas' Hospital in London and the ''Epidimiologie de l'Ostioporose'' (EPIDOS) medical group in France suggest that moderate wine consumption may offer positive benefits to women, particularly elderly women, in retaining [[bone density]] and reducing the risk of developing [[osteoporosis]].<ref>J.

In early 2009, three independent studies published in the medical journal of ''Gastroenterology'' suggest that moderate wine consumption may reduce the risk of certain forms of esophageal cancers such as [[esophageal adenocarcinoma]] and the [[precancerous]] condition [[Barrett's esophagus]]. In one study, conducted by [[Kaiser Permanente]] in California, respondents who reported drinking no more than 1 glass of wine a day had a 56% decrease in the risk for developing Barrett's esophagus-a rate lower than that of heavy and non-drinkers. While heavy alcohol consumption has been proven to increase the risk of esophageal, these studies suggest that [[antioxidant]]s in wine may offer some benefit if consumed in moderation but there is not a conclusive link. In response to these studies, Dr Prateek Sharma, MD, of the [[University of Kansas]] School of Medicine, notes that there maybe other links such as people who drink wine leading generally healthier lifestyles with consuming less fats and eating more fruits and vegetables.<ref> S.

===Resveratrol===
Research conducted at the [[Yale School of Public Health]] in 2009, suggest that wine may have some protective benefits against some forms of cancer. Women diagnosed with [[non-Hodgkin's lymphoma]] were questioned about their alcohol consumption patterns and followed for an 8 to 12 year period. Compared to non-drinkers, women who had drinking wine for at least 25 years prior were 33% less likely to die over the five-year period following diagnosis and 26% less likely to experience a relapse or develop a secondary cancer during that same five year period. Of all the women in the study, 75% of those who drank at least 12 glasses of wine over the course of their lifetime were alive after 5 years compared to 66% of the women who never drank any wine. Women who drank beer and alcohol spirits showed no differences.<ref> C.

While alcohol itself has been linked as increasing the risk of breast cancer in women, a 2008 study by researchers at the [[University of Nebraska]] suggest that resveratrol may have some preventative benefits against breast cancer. Prolong exposure of breast cells to [[estrogen]] has long been suspected as to be a major risk factor for breast cancer. This exposure can cause toxic estrogen [[metabolite]]s to appear that react with [[DNA]] in the body to promote the development of [[tumor]]s. Researchers at the University of Nebraska exposed human breast cells grown in the laboratory to low doses of resveratrol and found that it created numerous positive outcomes. The exposure to resveratrol not only decreased the production of estrogen metabolites but it also increased production of an enzyme that destroys these metabolites. It also appeared to limit interaction between these metabolites and DNA, limiting the promotion of tumor development. The amount of resveratrol used in the study was a low dose concentration of 10 micromoles per liter. A typical glass of wine has a concentration between 9 to 28 micromoles per liter. However, this laboratory study does not suggest that consuming wine will produce the necessary concentration of resveratrol in the blood stream to have these cancer fighting properties.<ref> D.

Studies have shown that heavy drinkers put themselves at greater risk for [[heart disease]] and developing potentially fatal [[cardiac arrhythmia]]s. Excessive alcohol consumption can cause higher blood pressure, increase [[cholesterol]] levels and weakened heart muscles. For moderate drinkers, medical research indicates moderate wine consumption may lower the mortality rate and risk of heart of disease.<ref name="Oxford pg 341-342"/> Studies have shown that moderate wine drinker can improve the balance of [[low-density lipoprotein]] (LDL or "bad" cholesterol) to [[high-density lipoprotein]] (HDL "good" cholesterol), which has been theorized as to clean up or remove LDL from [[Atheroma|blocking]] [[arteries]].<ref name="diet">K. Zelman ''"[http://www.webmd.com/food-recipes/features/wine-how-much-is-good-for-you Wine: How Much Is Good for You?]"'' WebMD, Accessed: July 28th 2009 </ref> The main cause of [[heart attacks]] and the pain of [[Angina pectoris|angina]] is the lack of oxygen caused by [[blood clots]] and [[atheromatous plaque]] build up in the arteries. The alcohol in wine has [[anticoagulant]] properties that limits blood clotting by making the [[platelet]]s in the blood less prone to stick together and reducing the levels of [[fibrin]] protein that binds them together. However these anticoagulant properties of wine only stay in the system for a maximum of 24 hours after consumption. While having a glass of wine the night before may lower the risk of having a heart attack the next day, there is still the potential of [[long-term effects of alcohol]]. These anticoagulant properties can also be amplified adversely by binge drinking, with the individual becoming over-anticoagulated and at increase risk of a stroke or heart attack.<ref name="Oxford pg 341-342"/>


The production and concentration of resveratrol is not equal among all the varieties of [[grape varieties|wine grapes]]. Differences in [[clones (plant)|clones]], [[rootstock]], ''Vitis'' species as well as climate conditions can affect the production of resveratrol. Also, because resveratrol is part of the defence mechanism in grapevines against [[vine diseases|attack]] by fungi or [[grape disease]], the degree of exposure to fungal infection and grape diseases also appear to play a role. The [[Muscadinia]] family of vines, which has adapted over time through exposure to [[North American]] grape diseases such as [[phylloxera]], has some of the highest concentrations of resveratrol among wine grapes. Among the European ''[[Vitis vinifera]]'', grapes derived from the [[Burgundian (wine)|Burgundian]] [[Pinot (grape)|Pinot]] family tend to have substantially higher amounts of resveratrol than grapes derived from the Cabernet family of [[Bordeaux (wine)|Bordeaux]]. Wine regions with cooler, wetter climates that are more prone to grape disease and fungal attacks such as [[Oregon wine|Oregon]] and [[New York wine|New York]] tend to produce grapes with higher concentrations of resveratrol than warmer, dry climates like [[California wine|California]] and [[Australia wine|Australia]].<ref name="Robinson_2006" />{{rp|569}}
Additional studies have focused on the benefits of the phenolic compound resveratrol to cardiovascular health. Some studies suggest that the [[antioxidant]] properties of resveratrol inhibits the oxidative reaction that for LDL cholesterol and decreases the "stickiness" of platelets that form blood clots.
<ref name="Oxford pg 341-342"/>


Although red wine and white vine varieties produce similar amounts of resveratrol, red wine contains more than white, since red wines are produced by [[maceration (wine)|maceration]] (soaking the grape skins in the mash). Other winemaking techniques, such as the use of certain strains of [[yeast (wine)|yeast]] during [[fermentation (wine)|fermentation]] or [[lactic acid bacteria]] during [[malolactic fermentation]], can have an influence on the amount of resveratrol left in the resulting wines.

===Dementia and mental functions===

One of the [[short-term effects of alcohol]] is impaired [[mental function]], which can cause behavioral changes and [[memory impairment]]. Long term effects of heavy drinking can inhibits new brain cell development and increase the risk for developing [[major depressive disorder]]s. Studies have linked moderate alcohol consumption to lower risk of developing [[Alzheimer's]] and [[dementia]] though wine's role in this link is not yet fully understood.<ref name="Oxford pg 341-342"/> A 2009 study by [[Wake Forest University]] School of Medicine suggest that moderate alcohol consumption may help healthy adults ward off the risks of developing dementia but can accelerate declining memory for those already suffering from [[cognitive impairment]]. The reason for the potential positive benefit of moderate consumption is not yet identified and may even be unrelated to the alcohol but rather other shared lifestyle factors of moderate drinkers (such as exercise or diets). If it is the moderate consumption, researchers theorize that it maybe alcohol's role in promoting the production of "good cholesterol" which prevents blood platelets from sticking together. Another potential role of alcohol in the body maybe in stimulating the release of the chemical [[acetylcholine]] which influences brain function and memory.<ref>C.

===Early history===
[[File:Hippocrates Light.JPG|thumb|[[Hippocrates]], the father of modern medicine, prescribed wine for a variety of ailments including [[lethargy]] and [[diarrhea]].]]
[[File:De medicina V00117 00000006.tif|thumb|''De medicina'']]
When the [[Greeks]] introduced a more systematized approach to medicine, wine retained its prominent role. The Greek physician [[Hippocrates]] considered wine a part of a healthy [[diet (nutrition)|diet]], and advocated its use as a [[disinfectant]] for wounds, as well as a medium in which to mix other drugs for consumption by the patient. He also prescribed wine as a cure for various ailments ranging from diarrhea and lethargy to pain during childbirth.<ref name="Robinson_2006" />{{rp|433}}

The medical practices of the [[Ancient Rome|Romans]] involved the use of wine in a similar manner. In his 1st-century work ''[[De Medicina]]'', the Roman encyclopedist [[Aulus Cornelius Celsus]] detailed a long list of [[Ancient Greek (wine)|Greek]] and [[Roman wine]]s used for medicinal purposes. While treating [[gladiators]] in [[Asia Minor]], the Roman physician [[Galen]] would use wine as a disinfectant for all types of wounds, and even soaked exposed [[bowels]] before returning them to the body. During his four years with the gladiators, only five deaths occurred, compared to sixty deaths under the watch of the physician before him.<ref name="nutton73">{{cite journal | vauthors = Nutton V | title = The chronology of Galen's early career | journal = Classical Quarterly | volume = 23 | issue = 1 | pages = 158–71 | date = May 1973 | pmid = 11624046 | doi = 10.1017/S0009838800036600 | jstor = 638137 | s2cid = 35645790 }}</ref>


Religion still played a significant role in promoting wine's use for health. The Jewish [[Talmud]] noted wine to be ''"the foremost of all medicines: wherever wine is lacking, medicines become necessary."'' In his [[first epistle to Timothy]], [[Paul the Apostle]] recommended that his [[Saint Timothy|young colleague]] drink a little wine every now and then for the benefit of his stomach and digestion. While the [[Islamic]] [[Koran]] contained [[Islamic dietary laws#Alcohol|restrictions on all alcohol]], Islamic doctors such as the Persian [[Avicenna]] in the 11th century AD noted that wine was an efficient digestive aid but, because of the laws, were limited to use as a disinfectant while dressing wounds.

===Weight management===
===Risks of consumption===
The lack of safe [[drinking water]] may have been one reason for wine's popularity in medicine. Wine was still being used to sterilize water as late as the [[Hamburg]] [[cholera]] epidemic of 1892 in order to control the spread of the disease. However, the late 19th century and early 20th century ushered in a period of changing views on the role of [[alcohol (drug)|alcohol]] and, by extension, wine in health and society. The [[Temperance movement]] began to gain steam by touting the ills of [[alcoholism]], which was eventually defined by the medical establishment as [[Disease theory of alcoholism|a disease]]. Studies of the [[Long-term effects of alcohol consumption|long]]- and [[Short-term effects of alcohol consumption]] caused many in the medical community to reconsider the role of wine in medicine and diet.<ref name="Robinson_2006" />{{rp|433}} Soon, public opinion turned against consumption of alcohol in any form, leading to [[Prohibition in the United States]] and other countries. In some areas, wine was able to maintain a limited role, such as an exemption from Prohibition in the United States for "[[therapeutic]] wines" that were sold legally in drug stores. These wines were marketed for their supposed medicinal benefits, but some wineries used this measure as a loophole to sell large quantities of wine for recreational consumption. In response, the United States government issued a mandate requiring producers to include an [[emetic]] additive that would induce vomiting above the consumption of a certain dosage level.<ref name="Miscellany"/>

==Heavy metals in wine==

A glass of red wine

The health effects of wine are mainly determined by its active ingredient – alcohol.[1][2] Preliminary studies found that drinking small quantities of wine (up to one standard drink per day for women and one to two drinks per day for men), particularly of red wine, may be associated with a decreased risk of cardiovascular diseases, cognitive decline, stroke, diabetes mellitus, metabolic syndrome, and early death. Other studies found no such effects.[2][3][4]

Drinking more than the standard drink amount increases the risk of cardiovascular diseases, high blood pressure, atrial fibrillation, stroke, and cancer.[3][5] Mixed results are also observed in light drinking and cancer mortality.[5][6][7][8]

Risk is greater in young people due to binge drinking, which may result in violence or accidents.[3] About 88,000 deaths in the United States are estimated to be due to alcohol each year.[9] Alcoholism reduces a person's life expectancy by around ten years[10] and excessive alcohol use is the third leading cause of early death in the United States.[3] According to systematic reviews and medical associations, people who are non-drinkers should never start drinking wine nor any other alcoholic drink.[3][7][11]

The history of wine includes use as an early form of medication, being recommended variously as a safe alternative to drinking water, an antiseptic for treating wounds, a digestive aid, and as a cure for a wide range of ailments including lethargy, diarrhea, and pain from child birth.[12] Ancient Egyptian papyri and Sumerian tablets dating back to 2200 BC detail the medicinal role of wine, making it the world's oldest documented human-made medicine.[13]: 433  Wine continued to play a major role in medicine until the late 19th and early 20th century, when changing opinions and medical research on alcohol and alcoholism cast doubt on its role as part of a healthy lifestyle.

Moderate consumption

[edit]
Some doctors define "moderate" consumption as one 5 oz (150 ml) glass of wine per day for women and two glasses per day for men.[3]

Nearly all research into the positive medical benefits of wine consumption makes a distinction between moderate consumption and heavy or binge drinking.[3] Moderate levels of consumption vary by the individual according to age, sex, genetics, weight and body stature, as well as situational conditions, such as food consumption or use of drugs.[3] In general, women absorb alcohol more quickly than men due to their lower body water content, so their moderate levels of consumption may be lower than those for a male of equal age.[13]: 341–2  Some experts define "moderate consumption" as less than one 5-US-fluid-ounce (150 ml) glass of wine per day for women and two glasses per day for men.[3][14]

The view of consuming wine in moderation has a history recorded as early as the Greek poet Eubulus (360 BC) who believed that three bowls (kylix) were the ideal amount of wine to consume. The number of three bowls for moderation is a common theme throughout Greek writing; today the standard 750 ml wine bottle contains roughly the volume of three kylix cups (250 ml or 8 fl oz each).[15] However, the kylix cups would have contained a diluted wine, at a 1:2 or 1:3 dilution with water. In his circa 375 BC play Semele or Dionysus, Eubulus has Dionysus say:

Three bowls do I mix for the temperate: one to health, which they empty first, the second to love and pleasure, the third to sleep. When this bowl is drunk up, wise guests go home. The fourth bowl is ours no longer, but belongs to violence; the fifth to uproar, the sixth to drunken revel, the seventh to black eyes, the eighth is the policeman's, the ninth belongs to biliousness, and the tenth to madness and hurling the furniture.[16]

Emerging evidence suggests that "even drinking within the recommended limits may increase the overall risk of death from various causes".[17] A 2018 systematic analysis found that "The level of alcohol consumption that minimised harm across health outcomes was zero (95% UI 0·0–0·8) standard drinks per week".[18] On the other hand, a 2020 USDA systematic review found that "low average consumption was associated with lower risk of mortality compared with never drinking status".[19] As of 2022, "moderate" consumption is usually defined in average consumption per day while the patterns of consumption vary and may have implications for risks and effects on health (such as habituation from daily consumption or nonlinear dosage-harm associations from intermittent excessive alcohol use). According to the CDC, it would be important to focus on the amount people drink on the days that they drink.[17]

Effect on the body

[edit]

Bones

[edit]

Heavy alcohol consumption has been shown to have a damaging effect on the cellular processes that create bone tissue, and long-term alcoholic consumption at high levels increases the frequency of fractures.[20] A 2012 study found no relation between wine consumption and bone mineral density.[21]

Cancer

[edit]

The International Agency for Research on Cancer of the World Health Organization has classified alcohol as a Group 1 carcinogen.[22]

Cardiovascular system

[edit]
The anticoagulant properties of alcohol in wine may have the potential of reducing the risk of blood clots associated with several cardiovascular diseases

Professional cardiology associations recommend that people who are currently nondrinkers should abstain from drinking alcohol.[11] Heavy drinkers have increased risk for heart disease, cardiac arrhythmias, hypertension, and elevated cholesterol levels.[medical citation needed]

The alcohol in wine has anticoagulant properties that may limit blood clotting.[23]

Digestive system

[edit]

The risk of infection from the bacterium Helicobacter pylori, which is associated with gastritis and peptic ulcers, appears to be lower with moderate alcohol consumption.[24][25]

Headaches

[edit]

There are several potential causes of so-called "red wine headaches", including histamine and tannins from grape skin or other phenolic compounds in wine.[26] Sulfites – which are used as a preservative in wine – are unlikely to be a headache factor.[26] Wine, like other alcoholic beverages, is a diuretic which promotes dehydration that can lead to headaches (such as the case often experienced with hangovers),[12] indicating a need to maintain hydration when drinking wine and to consume in moderation.[26] A 2017 review found that 22% of people experiencing migraine or tension headaches identified alcohol as a precipitating factor, and red wine as three times more likely to trigger a headache than beer.[27]

Food intake

[edit]
Wine has a long history of being paired with food and may help reduce food intake by suppressing appetite.

Alcohol can stimulate the appetite so it is better to drink it with food. When alcohol is mixed with food, it can slow the stomach's emptying time and potentially decrease the amount of food consumed at the meal.[28]

A 150-millilitre (5-US-fluid-ounce) serving of red or white wine provides about 500 to 540 kilojoules (120 to 130 kilocalories) of food energy, while dessert wines provide more.[29] Most wines have an alcohol by volume (ABV) percentage of about 11%; the higher the ABV, the higher the energy content of a wine.[29]

Heavy metals

[edit]

In 2008, researchers from Kingston University in London discovered red wine[30] to contain high levels of toxic metals relative to other beverages in the sample. Although the metal ions, which included chromium, copper, iron, manganese, nickel, vanadium and zinc, were also present in other plant-based beverages, the sample wine tested significantly higher for all metal ions, especially vanadium.[31] Risk assessment was calculated using "target hazard quotients" (THQ), a method of quantifying health concerns associated with lifetime exposure to chemical pollutants. Developed by the Environmental Protection Agency in the US and used mainly to examine seafood, a THQ of less than 1 represents no concern while, for example, mercury levels in fish calculated to have THQs of between 1 and 5 would represent cause for concern.[32]

The researchers stressed that a single glass of wine would not lead to metal poisoning, pointing out that their THQ calculations were based on the average person drinking one-third of a bottle of wine (250 ml) every day between the ages of 18 and 80. However the "combined THQ values" for metal ions in the red wine they analyzed were reported to be as high as 125.[31] A subsequent study by the same university using a meta analysis of data based on wine samples from a selection of mostly European countries found equally high levels of vanadium in many red wines, showing combined THQ values in the range of 50 to 200, with some as high as 350.[33]

The findings sparked immediate controversy due to several issues: the study's reliance on secondary data; the assumption that all wines contributing to that data were representative of the countries stated; and the grouping together of poorly understood high-concentration ions, such as vanadium, with relatively low-level, common ions such as copper and manganese. Some publications pointed out that the lack of identifiable wines and grape varieties, specific producers or even wine regions, provided only misleading generalizations that should not be relied upon in choosing wines.[34][35]

In a news bulletin following the widespread reporting of the findings, the UK's National Health Service (NHS) were also concerned that "the way the researchers added together hazards from different metals to produce a final score for individual wines may not be particularly meaningful".[35] Commentators in the US questioned the relevance of seafood-based THQ assessments to agricultural produce, with the TTB, responsible for testing imports for metal ion contamination, have not detected an increased risk. George Solas, quality assessor for the Canadian Liquor Control Board of Ontario (LCBO) claimed that the levels of heavy metal contamination reported were within the permitted levels for drinking water in tested reservoirs.[34]

Whereas the NHS also described calls for improved wine labeling as an "extreme response" to research which provided "few solid answers", they acknowledged the authors call for further research to investigate wine production, including the influence that grape variety, soil type, geographical region, insecticides, containment vessels and seasonal variations may have on metal ion uptake.[35]

Chemical composition

[edit]

Natural phenols and polyphenols

[edit]

Although red wine contains many chemicals under basic research for their potential health benefits, resveratrol has been particularly well studied and evaluated by regulatory authorities, such as the European Food Safety Authority and US Food and Drug Administration which identified it and other such phenolic compounds as not sufficiently understood to confirm their role as physiological antioxidants.[36][37]

Resveratrol

[edit]

Red wine contains an average of 1.9 (±1.7) mg of trans-resveratrol per liter.[38] For comparison, dietary supplements of resveratrol (trans-resveratrol content varies) may contain as much as 500 mg.[39][40]

Resveratrol is a stilbenoid phenolic compound found in wine produced in the grape skins and leaves of grape vines.[13]: 569 

The production and concentration of resveratrol is not equal among all the varieties of wine grapes. Differences in clones, rootstock, Vitis species as well as climate conditions can affect the production of resveratrol. Also, because resveratrol is part of the defence mechanism in grapevines against attack by fungi or grape disease, the degree of exposure to fungal infection and grape diseases also appear to play a role. The Muscadinia family of vines, which has adapted over time through exposure to North American grape diseases such as phylloxera, has some of the highest concentrations of resveratrol among wine grapes. Among the European Vitis vinifera, grapes derived from the Burgundian Pinot family tend to have substantially higher amounts of resveratrol than grapes derived from the Cabernet family of Bordeaux. Wine regions with cooler, wetter climates that are more prone to grape disease and fungal attacks such as Oregon and New York tend to produce grapes with higher concentrations of resveratrol than warmer, dry climates like California and Australia.[13]: 569 

Although red wine and white vine varieties produce similar amounts of resveratrol, red wine contains more than white, since red wines are produced by maceration (soaking the grape skins in the mash). Other winemaking techniques, such as the use of certain strains of yeast during fermentation or lactic acid bacteria during malolactic fermentation, can have an influence on the amount of resveratrol left in the resulting wines. Similarly, the use of certain fining agents during the clarification and stabilization of wine can strip the wine of some resveratrol molecules.[13]: 569 

Anthocyanins

[edit]

Red grapes are high in anthocyanins which are the source of the color of various fruits, such as red grapes. The darker the red wine, the more anthocyanins present.[41][original research?]

Typical concentrations of free anthocyanins in full-bodied young red wines are around 500 mg per liter.[42] For comparison, 100 g of fresh bilberry contain 300–700 mg[43] and 100 g FW elderberry contain around 603–1265 mg.[44]

Following dietary ingestion, anthocyanins undergo rapid and extensive metabolism that makes the biological effects presumed from in vitro studies unlikely to apply in vivo.[37][45]

Although anthocyanins are under basic and early-stage clinical research for a variety of disease conditions, there exists no sufficient evidence that they have any beneficial effect in the human body.[37] The US FDA has issued warning letters, e.g.,[46] to emphasize that anthocyanins are not a defined nutrient, cannot be assigned a dietary content level and are not regulated as a drug to treat any human disease.[37]

History of wine in medicine

[edit]

Early medicine was intimately tied with religion and the supernatural, with early practitioners often being priests and magicians. Wine's close association with ritual made it a logical tool for these early medical practices. Tablets from Sumeria and papyri from Egypt dating to 2200 BC include recipes for wine based medicines, making wine the oldest documented human-made medicine.[13]: 433 

Early history

Hippocrates, the father of modern medicine, prescribed wine for a variety of ailments including lethargy and diarrhea.

When the Greeks introduced a more systematized approach to medicine, wine retained its prominent role. The Greek physician Hippocrates considered wine a part of a healthy diet, and advocated its use as a disinfectant for wounds, as well as a medium in which to mix other drugs for consumption by the patient. He also prescribed wine as a cure for various ailments ranging from diarrhea and lethargy to pain during childbirth.[13]: 433 

The medical practices of the Romans involved the use of wine in a similar manner. In his 1st-century work De Medicina, the Roman encyclopedist Aulus Cornelius Celsus detailed a long list of Greek and Roman wines used for medicinal purposes. While treating gladiators in Asia Minor, the Roman physician Galen would use wine as a disinfectant for all types of wounds, and even soaked exposed bowels before returning them to the body. During his four years with the gladiators, only five deaths occurred, compared to sixty deaths under the watch of the physician before him.[47]

Religion still played a significant role in promoting wine's use for health. The Jewish Talmud noted wine to be "the foremost of all medicines: wherever wine is lacking, medicines become necessary." In his first epistle to Timothy, Paul the Apostle recommended that his young colleague drink a little wine every now and then for the benefit of his stomach and digestion. While the Islamic Koran contained restrictions on all alcohol, Islamic doctors such as the Persian Avicenna in the 11th century AD noted that wine was an efficient digestive aid but, because of the laws, were limited to use as a disinfectant while dressing wounds. Catholic monasteries during the Middle Ages also regularly used wine for medical treatments.[13]: 433  So closely tied was the role of wine and medicine, that the first printed book on wine was written in the 14th century by a physician, Arnaldus de Villa Nova, with lengthy essays on wine's suitability for treatment of a variety of medical ailments such dementia and sinus problems.[48]

Risks of consumption

[edit]

The lack of safe drinking water may have been one reason for wine's popularity in medicine. Wine was still being used to sterilize water as late as the Hamburg cholera epidemic of 1892 in order to control the spread of the disease. However, the late 19th century and early 20th century ushered in a period of changing views on the role of alcohol and, by extension, wine in health and society. The Temperance movement began to gain steam by touting the ills of alcoholism, which was eventually defined by the medical establishment as a disease. Studies of the long- and Short-term effects of alcohol consumption caused many in the medical community to reconsider the role of wine in medicine and diet.[13]: 433  Soon, public opinion turned against consumption of alcohol in any form, leading to Prohibition in the United States and other countries. In some areas, wine was able to maintain a limited role, such as an exemption from Prohibition in the United States for "therapeutic wines" that were sold legally in drug stores. These wines were marketed for their supposed medicinal benefits, but some wineries used this measure as a loophole to sell large quantities of wine for recreational consumption. In response, the United States government issued a mandate requiring producers to include an emetic additive that would induce vomiting above the consumption of a certain dosage level.[12]

The French paradox indicates that a diet high in fatty dairy products, such as cheeses, may be offset by red wine consumption to lower the risk of heart disease.

Throughout the mid to early 20th century, health advocates pointed to the risk of alcohol consumption and the role it played in a variety of ailments such as blood disorders, high blood pressure, cancer, infertility, liver damage, muscle atrophy, psoriasis, skin infections, strokes, and long-term brain damage. Studies showed a connection between alcohol consumption among pregnant mothers and an increased risk of mental retardation and physical abnormalities in what became known as fetal alcohol syndrome, prompting the use of alcohol packaging warning messages in several countries.[13]: 341–2 

French paradox

[edit]

The hypothesis of the French paradox assumes a low prevalence of heart disease due to the consumption of red wine despite a diet high in saturated fat.[49] Although epidemiological studies indicate red wine consumption may support the French paradox, there is insufficient clinical evidence to confirm it, as of 2017.[49]

Nevertheless, some cancer risk persists even at low levels of consumption. A meta-analysis that focused solely on cancer risks associated with drinking one drink or fewer per day observed that this level of alcohol consumption was still associated with some elevated risk for squamous cell carcinoma of the esophagus (sRR, 1.30; 95% CI, 1.09 to 1.56), oropharyngeal cancer (sRR, 1.17; 95% CI, 1.06 to 1.29), and breast cancer (sRR, 1.05; 95% CI, 1.02 to 1.08), but no discernable associations were seen for cancers of the colorectum, larynx, and liver.
