The Claim
High levels of meat consumption eliminate the cognitive disadvantage associated with the APOE34/44 genotype, resulting in cognitive trajectories and dementia risk equivalent to those observed in individuals without this genotype.
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.
People with the APOE34/44 genotype who consume high amounts of meat have the same cognitive function and dementia risk as people without this genotype.
See the scientific wording
The cognitive disadvantage typically associated with the APOE34/44 genotype is eliminated at high levels of meat consumption, bringing cognitive trajectories and dementia risk in these individuals to levels comparable to those without the genotype.
When people with the APOE34/44 genotype eat large amounts of meat, their bodies absorb more vitamin B12 from the food. This extra vitamin B12 helps nerve cells make myelin and break down harmful substances, which keeps their brains working properly and prevents memory loss and dementia.
What the research says
1 studyStudy: Meat Consumption and Cognitive Health by APOE Genotype
People with a certain gene variant usually have a higher risk of memory problems and dementia, but this study found that those who ate a lot of meat (about 930 grams per week) had memory and thinking skills as good as people without the gene, and were much less likely to get dementia.
