In fact, according to a double-blind, placebo-controlled study that examined responses to stimulants, an individual's subjective response to caffeine may predict how he or she will respond to other stimulant drugs, possibly reflecting differences in risk for abuse of other more serious drugs of abuse, such as amphetamine and cocaine. http://medicalxpress.com/news/2011-10-jonesing-java-caffeine-cocaine-abuse.html Other Fri, 07 Oct 2011 10:59:45 EST news237203973 The risk of depression appears to decrease for women with increasing consumption of caffeinated coffee, according to a report in the September 26 issue of Archives of Internal Medicine. http://medicalxpress.com/news/2011-09-caffeinated-coffee-consumption-decreased-depression.html Health Mon, 26 Sep 2011 16:25:29 EST news236273115 There might be a time when instead of just drinking that morning cup of coffee you lather it on your skin as a way of preventing harmful sun damage or skin cancer. http://medicalxpress.com/news/2011-08-evidence-caffeine-lowers-skin-cancer.html Cancer Mon, 15 Aug 2011 15:15:56 EST news232640131 Caffeine reduces muscle activity in the Fallopian tubes that carry eggs from a woman's ovaries to her womb. "Our experiments were conducted in mice, but this finding goes a long way towards explaining why drinking caffeinated drinks can reduce a woman's chance of becoming pregnant," says Sean Ward, professor of physiology and cell biology, at the University of Nevada School of Medicine, who conducted the study. http://medicalxpress.com/news/2011-07-caffeine-consumption-female-infertility-link.html Medical research Wed, 20 Jul 2011 12:46:44 EST news230384776 Research to be presented at the upcoming annual meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, indicates that caffeine added to sugar-sweetened, carbonated beverages teaches adolescents to prefer those beverages. Researchers found that the amount of caffeine added to an unfamiliar beverage was correlated with how much teenagers liked that beverage. http://medicalxpress.com/news/2011-07-caffeine-flavor-adolescents.html Health Tue, 12 Jul 2011 02:49:56 EST news229657772 A yet unidentified component of coffee interacts with the beverage's caffeine, which could be a surprising reason why daily coffee intake protects against Alzheimer's disease. A new Alzheimer's mouse study by researchers at the University of South Florida found that this interaction boosts blood levels of a critical growth factor that seems to fight off the Alzheimer's disease process. http://medicalxpress.com/news/2011-06-mystery-ingredient-coffee-boosts-alzheimer.html Health Tue, 21 Jun 2011 09:41:14 EST news227868030 Caffeine reduces muscle activity in the Fallopian tubes that carry eggs from a woman's ovaries to her womb.
