Chocolate may boost cognitive function


IF you’re looking for an excuse to chomp that bar of chocolate calling your name, then look no further; a new study suggests eating chocolate at least once weekly may boost cognitive function.Eating chocolate at least once weekly may benefit cognitive function, new research suggests.Dr. Georgie Crichton, of the Nutritional Physiology Research Centre at the University of South Australia, and colleagues publish their findings in the journal Appetite.While chocolate is still perceived as an indulgent treat, studies have increasingly documented the potential health benefits of habitual consumption.Earlier this month, for example, Medical News Today reported on a study suggesting that eating chocolate daily during pregnancy may benefit fetal growth and development, while an earlier study claims daily chocolate consumption may lower risk of stroke and heart disease. But how does chocolate intake impact cognitive function? This is what Dr. Crichton and colleagues set out to determine, noting that there is lack of information in this area.
“Little is known about the relationship between chocolate and cognitive functioning or brain health,” Dr. Crichton told MNT. “Most of the studies to date have focused on the acute effects of chocolate or cocoa consumption – i.e. consume a chocolate bar/cocoa-rich drink and assess immediate performance. We wanted to examine habitual or normal consumption with cognitive performance.”
Better cognitive performance with chocolate intake at least once weekly
The researchers analyzed the data of 968 people aged 23-98 who were free of dementia and part of the Maine-Syracuse Longitudinal Study (MSLS), which was led by study coauthor Prof. Merrill Elias, of the University of Maine.
The team analyzed the chocolate intake of participants over a 30-year period, as determined by information from a food frequency questionnaire. The questionnaire asked subjects how often they ate chocolate: never, rarely, once a week, two to four times a week, five to six times a week or once or more each day.
The cognitive function of participants was assessed through a series of tasks that tested visual-spatial memory and organization (the ability to understand and remember spatial relations among objects), working memory (the ability to process new and existing information), verbal memory (the ability to remember words and other factors related to language) and scanning and tracking (the ability to focus on specific objects).
The researchers found that individuals who consumed chocolate at least once a week performed significantly better on all cognitive tasks, compared with those who never or rarely ate chocolate.
