Processed meat consumption and dementia risk research

Recent scientific discussions have addressed claims that consuming two slices of processed meat per day can increase dementia risk by 44 percent. This specific figure stems from a 2021 study conducted by the University of Leeds, which analyzed data from nearly 500,000 individuals in the UK Biobank.

An international research team recently published a comprehensive review in the journal ‘Annual Review of Nutrition’ regarding the long-term effects of ultra-processed foods on brain health. The review seeks to provide context to the 2021 findings, noting that the relationship between processed meat consumption and dementia is complex and requires nuanced understanding beyond single headlines.
