New Review Links 25g Daily Deli Meat Intake to 44% Higher Dementia Risk
A new review in the Annual Review of Nutrition finds that consuming just 25 grams of processed meat daily, equivalent to one or two slices of deli meat, is associated with a 44% higher risk of all-cause dementia and a 52% higher risk of Alzheimer's disease. Led by Owen Carmichael, the study suggests that ultra-processed foods may contribute to brain aging. While the evidence remains observational and does not prove causation, experts note that replacing 10% of ultra-processed food calories with whole foods could lower dementia risk by 19%.
