A previous study that seemed to be good news for chocolate lovers has been challenged by the results of newer research, Docwire reports.
A report published last year concluded that consumption of dark chocolate could result in short-term improved vision — but a new, similarly designed study did not reach the same conclusion.
“In contrast to a previous trial reporting beneficial effects of dark chocolate flavanol on visual function, this similarly sized trial did not find any effects on subjective (visual function) or objective (retinal perfusion) end points,” announced the newer report. Both reports were published in JAMA Ophthalmology.
Both trials were relatively small, and the researchers in the more recent study said they could not tule out the possibility that dark chocolate consumption could bring benefits.
