On the impact of diet on dementia risk, ARUK’s doctor Imarisio said: “A growing body of research is looking at what lifestyle factors make up our risk of dementia, and diet has been frequently studied as part of this.
“This study shows that the effect of diet on dementia risk was not significant and did not reduce participant’s risk of developing Alzheimer’s disease or vascular dementia. Previous research, including reviews of multiple studies, has indicated that a Mediterranean-style diet may be associated with a lower risk of dementia.
“This study recruited people in their midlife, a critical time window for modifiable risk factors to be changed in order to reduce dementia risk in later life.”
Doctor Imarisio added: “In contrast to previous studies also looking at the effect of diet on dementia risk, people involved in this research had three different measures of their dietary habits through a self-reported diary, a detailed questionnaire and an in-person interview. This can limit errors in reporting dietary habits, as it does not rely on people remembering habits from years beforehand.”
