New research suggests that a diet rich in ultraprocessed foods like processed meats and sugary drinks may significantly increase the risk of dementia and cognitive decline.
Dana G. Smith and Alice Callahan report for The New York Times.
In short:
- A study following over 130,000 Americans linked consuming processed red meats such as bacon and hot dogs to a 14% increased risk of dementia.
- Additional research suggests diets high in ultraprocessed foods could harm brain health by affecting blood vessels, displacing healthy nutrients and promoting inflammation.
- Experts recommend gradual dietary changes to replace ultraprocessed foods with healthier options like fruits, vegetables, and lean proteins.
