A study from Harvard’s T.H. Chan School of Public Health reveals that consuming over two pounds of ultraprocessed foods daily raises the risk of developing dementia by 58% and cognitive impairment by 46%. The research highlights the growing prevalence of ultraprocessed foods in the American diet and its potential health impacts.
- 01More than 7.2 million Americans currently live with Alzheimer’s disease, with projections suggesting this could rise to nearly 13 million by 2050.
- 02Around 70% of the American diet consists of ultraprocessed foods, which are designed to be hyperpalatable.
- 03Even moderate consumption of ultraprocessed foods, defined as about a pound or less daily, is associated with increased risks.
- 04Processed meats, such as bacon and sliced ham, are linked to the highest dementia risk.
- 05Minimally processed foods, like fruits and vegetables, can lower dementia risk by 41%.

A recent study conducted by researchers at Harvard’s T.H. Chan School of Public Health found that individuals consuming over two pounds of ultraprocessed foods daily face a 58% higher risk of developing dementia and a 46% increased risk of cognitive impairment. This alarming trend is linked to the fact that approximately 70% of the American diet has become ultraprocessed over the past 50 years. The study analyzed the health data of over 5,300 older adults over nearly a decade, revealing that those who consumed processed meats had the highest risk for dementia. While the study's self-reported data prevents definitive causation conclusions, ultraprocessed foods are associated with various risk factors for dementia, including obesity and cardiovascular disease. Experts recommend reducing ultraprocessed food intake, as those who consume more minimally processed foods like fruits and vegetables show a 41% lower risk of dementia. This research underscores the importance of dietary choices in mitigating cognitive decline.
