Preparing a Home-Cooked Meal Once a Week May Cut Older People’s Dementia Risk

Preparing a home-cooked meal at least once a week may cut older people’s risk of dementia by 30%, suggests research published online in the Journal of Epidemiology & Community Health.

This risk may also be 70% lower in older novice cooks with few culinary skills, the findings indicate. The findings may not apply more widely because what food is eaten, and how it is prepared, vary from culture to culture, state the researchers.

Nevertheless, the study concludes: “Creating an environment where people can cook meals when they are older may be important for the prevention of dementia.”
