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.<ref name=Kummer2003>Kummer, Corby (2003). ''[http://books.google.com/books?id=qNLrJqgfg7wC The Joy of Coffee]'', [http://books.google.com/books?id=qNLrJqgfg7wC&pg=PA151&sig=zL7_XqPYPeBVq8vs3ukYFuwjn2I Caffeine and Decaf], Houghton Mifflin Cookbooks, 160-165.

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.<ref>Pereira, Mark A.; Parker, D.; Folsom, A.R. (2006). "[http://archinte.ama-assn.org/cgi/content/full/166/12/1311 Coffee consumption and risk of type 2 diabetes mellitus: an 11-year prospective study of 28 812 postmenopausal women]".

Coffee's negative health effects are mostly due to its [[caffeine]] content. Research suggests that drinking caffeinated coffee can cause a temporary increase in the stiffening of arterial walls.<ref>Mahmud, A.; Feely, J. (2001).

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.<ref>BBC News; Lesk, Valerie (2004-07-20).
