This Simple Habit Could Cut Your Risk of Dementia by 30%

Regularly cooking meals at home was linked to lower dementia risk in older adults.

Preparing meals just once a week was associated with a meaningful drop in risk.

Overall, dementia risk was about 30% lower among those who cooked at home.

The risk reduction approached 70% for people with little prior cooking experience.

The analysis followed 10,978 adults aged 65+ (about 20% were 80+) for six years through 2022 from the Japan Gerontological Evaluation Study (JAGES).
