Preparing a home cooked meal at least once a week may cut older people's dementia risk by 30%, study finds
Older adults cooking at home weekly had about 30% lower dementia risk, with up to 70% lower risk for those with fewer cooking skills, study authors said.
On Tuesday, a study in the Journal of Epidemiology & Community Health found older adults who cook at least once a week have a 30% lower risk of dementia, based on data from 10,978 Japanese participants aged at least 65 tracked for six years.
Researchers said that preparing meals "provides opportunities for cognitive stimulation because it involves a cognitively complex series of tasks with multiple steps," such as planning, acquiring ingredients, and serving.
Author Yukako Tani noted benefits were particularly significant for participants with fewer culinary skills, who experienced a 70% lower risk of dementia, likely because cooking serves as a novel cognitive experience.
Finished meals and delivery meals save time and effort. But those who cook regularly themselves could significantly reduce their risk of dementia, especially in older age.
