About The Study: In this study, higher meat consumption was associated with better cognitive trajectories and lower dementia risk among individuals with APOE34/44 genotypes. The expected cognitive disadvantage among individuals with APOE34/44 genotypes was not observed at high meat consumption, suggesting clinical and public health relevance. The apolipoprotein E (APOE) ε4 allele increases Alzheimer disease risk.
