A team of researchers discovered that cholecystokinin (CCK), a satiety hormone which is highly expressed in memory formation, could, at higher levels, decrease a person's likelihood of developing Alzheimer's disease by 65 per cent, said the study published in the journal Neurobiology of Aging.
The researchers hope this study will encourage others to look into the nutritional aspect of diets, versus just looking at caloric intake.
Also, Alexandra Plagman, who is the lead author and graduate student at the varsity, is currently looking at how diet impacts an individual's CCK levels through researching fasting glucose and ketone bodies.
"By looking at the nutritional aspect, we can tell if a certain diet could prevent Alzheimer's disease or prevent progression of the disease," Plagman said.
Using data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), the team looked at CCK in 287 people.
