Scientific studies have examined the relationship between coffee consumption and an array of medical conditions. Findings are contradictory as to whether coffee has any specific health benefits, and results are similarly conflicting regarding negative effects of coffee consumption.[1]

Coffee appears to reduce the risk of Alzheimer's disease, Parkinson's disease, heart disease, diabetes mellitus type 2, cirrhosis of the liver,[2] and gout. Some health effects are due to the caffeine content of coffee, as the benefits are only observed in those who drink caffeinated coffee, while others appear to be due to other components.[3] For example, the antioxidants in coffee prevent free radicals from causing cell damage.[4]

Although caffeine has not been linked to any life-threatening disease, doctors and nurses routinely advise some patients to watch their caffeine intake or to eliminate it altogether.[5] Research suggests that drinking caffeinated coffee can cause a temporary increase in the stiffening of arterial walls.[6] Excess coffee consumption may lead to a magnesium deficiency or hypomagnesaemia,[7] and may be a risk factor for coronary heart disease. Some studies suggest that it may have a mixed effect on short-term memory, by improving it when the information to be recalled is related to the current train of thought, but making it more difficult to recall unrelated information.[8] About 10% of people with a moderate daily intake (235 mg per day) reported increased depression and anxiety when caffeine was withdrawn,[9] and about 15% of the general population report having stopped caffeine use completely, citing concern about health and unpleasant side effects.[10] Nevertheless, the mainstream view of medical experts is that drinking three 8-ounce (236 ml) cups of coffee per day (considered average or moderate consumption) does not have significant health risks for adults.[11]

Rendering:

Scientific studies have examined the relationship between coffee consumption and an array of medical conditions. Findings are contradictory as to whether coffee has any specific health benefits, and results are similarly conflicting regarding negative effects of coffee consumption.[1]

Coffee appears to reduce the risk of Alzheimer's disease, Parkinson's disease, heart disease, diabetes mellitus type 2, cirrhosis of the liver,[2] and gout. Some health effects are due to the caffeine content of coffee, as the benefits are only observed in those who drink caffeinated coffee, while others appear to be due to other components.[3] For example, the antioxidants in coffee prevent free radicals from causing cell damage.[4]

Although caffeine has not been linked to any life-threatening disease, doctors and nurses routinely advise some patients to watch their caffeine intake or to eliminate it altogether.[1] Research suggests that drinking caffeinated coffee can cause a temporary increase in the stiffening of arterial walls.[5] Excess coffee consumption may lead to a magnesium deficiency or hypomagnesaemia,[6] and may be a risk factor for coronary heart disease. Some studies suggest that it may have a mixed effect on short-term memory, by improving it when the information to be recalled is related to the current train of thought, but making it more difficult to recall unrelated information.[7] About 10% of people with a moderate daily intake (235 mg per day) reported increased depression and anxiety when caffeine was withdrawn,[8] and about 15% of the general population report having stopped caffeine use completely, citing concern about health and unpleasant side effects.[9] Nevertheless, the mainstream view of medical experts is that drinking three 8-ounce (236 ml) cups of coffee per day (considered average or moderate consumption) does not have significant health risks for adults.[10]

Shortened notes linked with ((sfn)) and citation templates

This is an example edit mode representation showing use of shortened notes written using ((sfn)) with citation templates. Templates in the ((cite xxx)) and ((citation)) families allow linking from ((sfn)) via matching author last names and year (part of date). Overriding ref parameter CITEREFSurnameYear may also be used (e.g. when coauthor names mismatch).

A template call like ((sfn|Smith|2007|p=25)) is equivalent to <ref>((harvnb|Smith|2007|p=25)).</ref>, except that it automatically combines identical footnotes. (To get the equivalent effect using the ((harvnb)) construction, you'd need to add matching name= parameters to the footnotes to be combined.) The longer form can be used if more control is needed. 

Scientific studies have examined the relationship between coffee consumption and an array of medical conditions. Findings are contradictory as to whether coffee has any specific health benefits, and results are similarly conflicting regarding negative effects of coffee consumption.((sfn|Kummer|2003|pp=151–170))

Coffee appears to reduce the risk of [[Alzheimer's disease]], [[Parkinson's disease]], [[heart disease]], [[diabetes mellitus type 2]], [[cirrhosis]] of the [[liver]],((sfn|Klatsky|Morton|Udaltsova|Friedman|2006)) and [[gout]]. Some health effects are due to the [[caffeine]] content of coffee, as the benefits are only observed in those who drink caffeinated coffee, while others appear to be due to other components.((sfn|Pereira|Parker|Folsom|2006)) For example, the [[antioxidant]]s in coffee prevent [[Radical (chemistry)|free radicals]] from causing cell damage.((sfn|Bakalar|2006))

Although caffeine has not been linked to any life-threatening disease, doctors and nurses routinely advise some patients to watch their caffeine intake or to eliminate it altogether.((sfn|Kummer|2003|p=152)) Research suggests that drinking caffeinated coffee can cause a temporary increase in the stiffening of arterial walls.((sfn|Mahmud|Feely|2001)) Excess coffee consumption may lead to a [[magnesium deficiency (medicine)|magnesium deficiency]] or [[hypomagnesaemia]],((sfn|Johnson|2001)) and may be a risk factor for [[coronary heart disease]]. Some studies suggest that it may have a mixed effect on [[short-term memory]], by improving it when the information to be recalled is related to the current [[train of thought]], but making it more difficult to recall unrelated information.((sfn|Lesk|2004)) About 10% of people with a moderate daily intake (235 mg per day) reported increased depression and anxiety when caffeine was withdrawn,((sfn|Smith|2002)) and about 15% of the general population report having stopped caffeine use completely, citing concern about health and unpleasant side effects.((sfn|Johns Hopkins|2003)) Nevertheless, the mainstream view of medical experts is that drinking three 8-ounce (236 ml) cups of coffee per day (considered average or moderate consumption) does not have significant health risks for adults.((sfn|Haines|2007))

Scientific studies have examined the relationship between coffee consumption and an array of medical conditions. Findings are contradictory as to whether coffee has any specific health benefits, and results are similarly conflicting regarding negative effects of coffee consumption.[1]

Coffee appears to reduce the risk of Alzheimer's disease, Parkinson's disease, heart disease, diabetes mellitus type 2, cirrhosis of the liver,[2] and gout. Some health effects are due to the caffeine content of coffee, as the benefits are only observed in those who drink caffeinated coffee, while others appear to be due to other components.[3] For example, the antioxidants in coffee prevent free radicals from causing cell damage.[4]

Although caffeine has not been linked to any life-threatening disease, doctors and nurses routinely advise some patients to watch their caffeine intake or to eliminate it altogether.[5] Research suggests that drinking caffeinated coffee can cause a temporary increase in the stiffening of arterial walls.[6] Excess coffee consumption may lead to a magnesium deficiency or hypomagnesaemia,[7] and may be a risk factor for coronary heart disease. Some studies suggest that it may have a mixed effect on short-term memory, by improving it when the information to be recalled is related to the current train of thought, but making it more difficult to recall unrelated information.[8] About 10% of people with a moderate daily intake (235 mg per day) reported increased depression and anxiety when caffeine was withdrawn,[9] and about 15% of the general population report having stopped caffeine use completely, citing concern about health and unpleasant side effects.[10] Nevertheless, the mainstream view of medical experts is that drinking three 8-ounce (236 ml) cups of coffee per day (considered average or moderate consumption) does not have significant health risks for adults.[11]

Parenthetical references[edit]

This style of citation was a type of referencing used on Wikipedia until September 2020, when a community discussion reached a consensus to deprecate this format of citation.

Inline parenthetical references are conceptually very much like shortened footnotes, but insert the shortened reference inline into the article body text rather than in a footnote. The advantages are that the source of the reference is shown more clearly, and getting to the full citation takes only one click rather than two with shortened footnotes (one to reach the shortened footnote, a second to reach the full citation). The disadvantage, though, is that the references clutter up the article text, and for this reason, parenthetical references are not nearly as common as shortened footnotes in Wikipedia articles.

Parenthetical references with references written freehand

This is an example edit mode representation showing use of inline parenthetical references, written freehand. Done this way, there is no linking from the references to the citation, so the user has to manually scroll down to find the citation. 

Scientific studies have examined the relationship between coffee consumption and an array of medical conditions. Findings are contradictory as to whether coffee has any specific health benefits, and results are similarly conflicting regarding negative effects of coffee consumption (Kummer 2003, pp. 151–170).

Coffee appears to reduce the risk of [[Alzheimer's disease]], [[Parkinson's disease]], [[heart disease]], [[diabetes mellitus type 2]], [[cirrhosis]] of the [[liver]] (Klatsky 2006), and [[gout]]. Some health effects are due to the [[caffeine]] content of coffee, as the benefits are only observed in those who drink caffeinated coffee, while others appear to be due to other components (Pereira 2006). For example, the [[antioxidant]]s in coffee prevent [[Radical (chemistry)|free radicals]] from causing cell damage (Bakalar 2006).

Although caffeine has not been linked to any life-threatening disease, doctors and nurses routinely advise some patients to watch their caffeine intake or to eliminate it altogether (Kummer 2003, p. 152). Research suggests that drinking caffeinated coffee can cause a temporary increase in the stiffening of arterial walls (Mahmud 2001). Excess coffee consumption may lead to a [[magnesium deficiency (medicine)|magnesium deficiency]] or [[hypomagnesaemia]] (Johnson 2001) and may be a risk factor for [[coronary heart disease]]. Some studies suggest that it may have a mixed effect on [[short-term memory]], by improving it when the information to be recalled is related to the current [[train of thought]], but making it more difficult to recall unrelated information (BBC 2004). About 10% of people with a moderate daily intake (235 mg per day) reported increased depression and anxiety when caffeine was withdrawn (Smith 2002), and about 15% of the general population report having stopped caffeine use completely, citing concern about health and unpleasant side effects (Johns Hopkins 2003). Nevertheless, the mainstream view of medical experts is that drinking three 8-ounce (236 ml) cups of coffee per day (considered average or moderate consumption) does not have significant health risks for adults (Haines 2007).

Parenthetical references linked with ((harv)) and citation templates

This is an example edit mode representation showing use of inline parenthetical references written using ((harv)) with citation templates. Templates in the ((cite xxx)) and ((citation)) families allow linking from ((harv)) via matching author last names and year (part of date). Overriding ref parameter CITEREFSurnameYear may also be used (e.g. when coauthor names mismatch).

Alternatives to ((harv)) are: 

Scientific studies have examined the relationship between coffee consumption and an array of medical conditions. Findings are contradictory as to whether coffee has any specific health benefits, and results are similarly conflicting regarding negative effects of coffee consumption ((harv|Kummer|2003|pp=151–170)).

Coffee appears to reduce the risk of [[Alzheimer's disease]], [[Parkinson's disease]], [[heart disease]], [[diabetes mellitus type 2]], [[cirrhosis]] of the [[liver]] ((harv|Klatsky|Morton|Udaltsova|Friedman|2006)), and [[gout]]. Some health effects are due to the [[caffeine]] content of coffee, as the benefits are only observed in those who drink caffeinated coffee, while others appear to be due to other components ((harv|Pereira|Parker|Folsom|2006)). For example, the [[antioxidant]]s in coffee prevent [[Radical (chemistry)|free radicals]] from causing cell damage ((harv|Bakalar|2006)).

Although caffeine has not been linked to any life-threatening disease, doctors and nurses routinely advise some patients to watch their caffeine intake or to eliminate it altogether ((harv|Kummer|2003|p=152)). Research suggests that drinking caffeinated coffee can cause a temporary increase in the stiffening of arterial walls ((harv|Mahmud|Feely|2001)). Excess coffee consumption may lead to a [[magnesium deficiency (medicine)|magnesium deficiency]] or [[hypomagnesaemia]] ((harv|Johnson|2001)), and may be a risk factor for [[coronary heart disease]]. Some studies suggest that it may have a mixed effect on [[short-term memory]], by improving it when the information to be recalled is related to the current [[train of thought]], but making it more difficult to recall unrelated information ((harv|Lesk|2004)). About 10% of people with a moderate daily intake (235 mg per day) reported increased depression and anxiety when caffeine was withdrawn ((harv|Smith|2002)), and about 15% of the general population report having stopped caffeine use completely, citing concern about health and unpleasant side effects ((harv|Johns Hopkins|2003)). Nevertheless, the mainstream view of medical experts is that drinking three 8-ounce (236 ml) cups of coffee per day (considered average or moderate consumption) does not have significant health risks for adults ((harv|Haines|2007)).
