Conclusions
dementia
This study showed that in middle-aged and older Japanese males and females, ingestion of 300 mg/day egg yolk choline increased plasma free choline levels and improved verbal memory, a part of cognitive function. It has been proposed that the consumption of egg yolk choline could potentially maintain cognitive function in individuals without dementia. However, it remains unclear that whether the intake of egg yolk choline could prevent or reduce the incidence of dementia. Nevertheless, it has been suggested that incorporating regular consumption of egg yolk choline into the diet is an effective strategy for maintaining brain function in adults who are free of dementia.
