Since 1977, there has been a 70% increase in caffeine consumption among children and adolescents. Whether it is coffee, tea, soda, or energy drinks, our children are consuming more of it. One well documented effect of caffeine is improved cognitive performance on certain tasks. However, scientists also hypothesize that habitual caffeine use may lead to greater neural rewards if the caffeine drinker were to consume illicit drugs. http://medicalxpress.com/news/2013-04-caffeine-effect-cognitive-tasks-food.html Health Mon, 22 Apr 2013 12:00:06 EST news285849631 We are often asked whether coffee is good or bad for the health.

Young people are increasingly turning to energy drinks to fuel study sessions, as well as coming to rely on them in everyday life.

The research published November 7 in the open access journal PLOS ONE by Lars Kuchinke and colleagues from Ruhr University, Germany, shows that caffeine enhances the neural processing of positive words, but not those with neutral or negative associations. http://medicalxpress.com/news/2012-11-caffeine-recognition-positive-words.html Neuroscience Wed, 07 Nov 2012 17:00:04 EST news271519669 Molecular imaging with positron emission tomography (PET) has enabled scientists for the first time to visualize binding sites of caffeine in the living human brain to explore possible positive and negative effects of caffeine consumption. According to research published in the November issue of The Journal of Nuclear Medicine, PET imaging with F-18-8-cyclopentyl-3-(3-fluoropropyl)-1-propylxanthine (F-18-CPFPX) shows that repeated intake of caffeinated beverages throughout a day results in up to 50 percent occupancy of the brain's A1 adenosine receptors. http://medicalxpress.com/news/2012-11-caffeine-effect-brain-adenosine-receptors.html Medical research Thu, 01 Nov 2012 13:38:56 EST news270995928 Recent studies have linked caffeine consumption to a reduced risk of Alzheimer's disease, and a new University of Illinois study may be able to explain how this happens. http://medicalxpress.com/news/2012-10-caffeine-block-inflammation-linked-mild.html Neuroscience Tue, 09 Oct 2012 15:21:20 EST news269014866 (HealthDay) -- Maternal prenatal caffeine intake is not associated with behavior problems in young children, according to a study published online July 9 in Pediatrics. http://medicalxpress.com/news/2012-07-prenatal-caffeine-intake-linked-children.html Pediatrics Mon, 09 Jul 2012 15:17:38 EST news261065851 The combined effects of exercise plus caffeine consumption may be able to ward off skin cancer and also prevent inflammation related to other obesity-linked cancers. http://medicalxpress.com/news/2012-04-caffeine-skin-cancer-sun-exposure.html Cancer Tue, 03 Apr 2012 14:42:25 EST news252682938 (HealthDay) -- Heavy caffeine consumption by nursing mothers does not increase the number of nighttime awakenings in 3-month-old infants, according to a study published online April 2 in Pediatrics. http://medicalxpress.com/news/2012-04-maternal-caffeine-intake-doesnt-affect.html Health Mon, 02 Apr 2012 14:00:05 EST news252589940 (Medical Xpress) -- Whether you are an elite athlete trying to gain a competitive edge, or a regular bike commuter, consuming caffeine one hour prior to exercise has the potential to improve your performance. http://medicalxpress.com/news/2012-03-scientists-effects-caffeine.html Health Wed, 21 Mar 2012 07:21:25 EST news251533274 Caffeine consumption has long been associated with decreased risk of liver disease and reduced fibrosis in patients with chronic liver disease. Now, newly published research confirms that coffee caffeine consumption reduces the risk of advanced fibrosis in those with nonalcoholic fatty liver disease (NAFLD). Findings published in the February issue of Hepatology, a journal of the American Association for the Study of Liver Diseases, show that increased coffee intake, specifically among patients with nonalcoholic steatohepatitis (NASH), decreases risk of hepatic fibrosis. http://medicalxpress.com/news/2012-02-coffee-consumption-fibrosis-fatty-liver.html Diseases, Conditions, Syndromes Thu, 02 Feb 2012 11:35:24 EST news247404915 Asian women who consumed an average of 200 milligrams or more of caffeine a day—the equivalent of roughly two cups of coffee—had elevated estrogen levels when compared to women who consumed less, according to a study of reproductive age women by researchers at the National Institutes of Health and other institutions. http://medicalxpress.com/news/2012-01-caffeine-consumption-linked-estrogen.html Health Thu, 26 Jan 2012 11:55:17 EST news246801305 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 Caffeine reduces muscle activity in the Fallopian tubes that carry eggs from a woman's ovaries to her womb.
