Dementia: 25 grams of processed meat per day may raise relative risk

  • An observational study suggests there is a link between consuming 25 grams (g) of processed meat per day — which amounts to around one rasher of bacon — and a 44% higher risk of dementia.
  • The study also found an association between eating unprocessed red meats, such as beef, pork, and veal, and reduced risks of all-cause dementia.
  • A gene variant known as the APOE ε4 allele, which increases a person’s risk of dementia by 3–6 times, did not appear to affect the relationship between diet and the condition.
