Common kitchen ingredient could reduce dementia death risks

Researchers have found evidence that consuming seven or more grams of olive oil could reduce dementia mortality risks. 
The study, which involved 92,383 American adults, found that those who ingested this amount of olive oil experienced a 28% reduction in dementia-related deaths. 
JAMA Network Open’s analysis collected data from 1990 to 2023 and was published Monday, Medical News reports.
The study’s 92,383 participants, of which 65.6 percent were female, recorded 4,751 dementia-associated deaths over these 33 years.
The Department of Nutrition, Harvard T.H. Chan School of Public Health, Boston, said: “Opting for olive oil, a natural product, instead of more processed fats such as margarine and mayonnaise, is a safe choice and may reduce risk of fatal dementia.

“Intervention studies are needed to confirm causal effect and optimal quantity of olive oil intake,” Medscape Medical News reports. 
JAMA Network Open wrote in its published study: “Olive oil intake was inversely associated with dementia-related mortality in age-stratified and multivariable-adjusted models. 
“Compared with participants with the lowest olive oil intake, the pooled HR for dementia-related death among participants with the highest olive oil intake (>7 g/d) was 0.72 (95% CI, 0.64-0.81), after adjusting for sociodemographic and lifestyle factors.”
