Numerous studies have suggested that caffeine has many health benefits. Now, new research suggests that a dose of caffeine after a learning session may help to boost long-term memory. This is according to a study published in the journal Nature Neuroscience. 200 mg of caffeine 'enhanced memory' Summary: From this, the researchers found that subjects who took the caffeine were better at identifying pictures that were similar, compared with participants who took the placebo. However, the researchers note that both groups were able to accurately distinguish whether pictures were old or new. New research suggests that consuming 200 mg of caffeine a day may boost long-term memory. The team conducted further experiments using 100 mg and 300 mg doses of caffeine. They found that performance was better after the 200 mg dose, compared with the 100 mg dose, but there was no improvement after the 300 mg of caffeine, compared with 200 mg. "Thus, we conclude that a dose of at least 200 mg is required to observe the enhancing effect of caffeine on consolidation of memory," the study authors write. The team also found that memory performance was not improved if subjects were given caffeine 1 hour before carrying out the picture identification test. They investigators say there are many possibilities as to how caffeine may enhance long-term memory. For example, they say it may block a molecule called adenosine, preventing it from stopping the function of nor epinephrine - a hormone that has been shown to have positive effects on memory. Two medical researchers writing in one of The Lancet journals argue that because of its high sugar content, fruit juice could be just as bad for us as sugar-sweetened beverages like carbonated drinks and sodas. "One glass of fruit juice contains substantially more sugar than one piece of fruit; in addition, much of the goodness in
