The Claim
Higher total meat consumption eliminates the expected cognitive disadvantage in older adults with the APOE34/44 genotype, resulting in cognitive trajectory and dementia risk levels equivalent to those without this genetic variant.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Older adults with the APOE34/44 genotype who consume more meat have the same cognitive function and dementia risk as older adults without this genetic variant.
See the scientific wording
Higher total meat consumption eliminates the expected cognitive disadvantage in older adults with the APOE34/44 genotype, bringing their cognitive trajectory and dementia risk to levels similar to those without this genetic risk variant.
In people with a specific gene variant that increases dementia risk, eating more meat helps their bodies absorb more vitamin B12 from food. This vitamin helps convert a harmful substance in the blood into a harmless one. When this harmful substance builds up, it damages blood vessels in the brain and kills brain cells. With more vitamin B12 from meat, this damage stops, brain cells stay healthy, and memory and thinking stay strong.
What the research says
1 studyStudy: Meat Consumption and Cognitive Health by APOE Genotype
In older adults with a gene that raises dementia risk, eating a lot of meat (like beef or chicken, not processed meats) was linked to better memory and less dementia — so much so that their brain health looked like people without the risky gene.
