Diet, Mood and Mental Performance 

The section of the HPRG is broadly interested in nutritional neuroscience, the effect of dietary factors on mood and cognitive performance. One line of research has focused on caffeine consumption; both the effects of caffeine (and caffeine withdrawal) on mood and mental performance, and personality and lifestyle factors that relate to the consumption of caffeinated drinks. Another area of interest is the effect of patterns of eating (how much and how often) on mood and mental performance.
