A recent study has established a correlation between diets rich in ultraprocessed foods and an elevated risk of developing dementia. The research indicated that individuals who consumed the largest quantities of these foods faced a 58% higher likelihood of later being diagnosed with dementia, and a 46% increased risk of cognitive impairment. This finding adds to a growing body of evidence linking ultraprocessed items, which encompass common products like cookies, hot dogs, and pizza, to various adverse health outcomes. Specifically, consuming bacon, ham, and other smoked meats was tied to the highest risk to brain health. CBS News medical correspondent Dr. Céline Gounder provided further details on the study.
