Story summary

A Karolinska Institutet-led Swedish study found that adults with APOE 3/4 or 4/4 genes who eat more meat show slower cognitive decline and lower dementia risk.
The study tracked over 2,100 participants for up to 15 years.
The findings suggest conventional dietary advice may not suit individuals with these genetic variants.
Researchers say further studies are needed to establish causal relationships and develop tailored dietary recommendations for this group.
