Seniors Who Eat More Meat Are Less Likely to Develop Dementia Study Find

Key Points:

• A Swedish study found that seniors carrying the APOE 3/4 or 4/4 gene variants, which increase Alzheimer’s risk, showed reduced cognitive decline and dementia risk when consuming higher amounts of meat, particularly unprocessed meat.
• The research tracked over 2,100 adults aged 60+ for up to 15 years and indicated that the top 20% of meat consumers (about 870 grams per week) among APOE risk carriers had significantly slower cognitive decline compared to those eating less meat.
• The study suggests that conventional dietary advice may not suit this genetic subgroup and highlights the potential for tailored nutritional recommendations based on APOE genotype.
• Researchers emphasized the observational nature of the study and called for clinical trials to confirm causal links and develop specific dietary guidelines for individuals with APOE4 variants.
• Additionally, a lower proportion of processed meat intake was linked to reduced dementia risk regardless of genotype, and higher unprocessed meat consumption was associated with lower early mortality in APOE risk carriers.
