Meat Eaters with APOE4 Gene May Slow Alzheimer's
26 Mar
Summary
- Higher meat consumption linked to slower cognitive decline in APOE4 carriers.
- Unprocessed meat intake associated with lower dementia risk regardless of APOE.
- Study suggests APOE4 carriers may have different dietary needs than general population.
A new observational study conducted in Sweden suggests a surprising link between meat consumption and a reduced risk of dementia for individuals carrying the APOE4 gene. This genetic variant is known as the strongest risk factor for developing Alzheimer's disease.
The research, published in JAMA Network Open, analyzed data from 2,157 adults over 60 in Stockholm. It found that those with APOE 3/4 or 4/4 gene variants who consumed higher amounts of meat showed significantly slower cognitive decline and a lower incidence of dementia.
Conversely, individuals with these genetic variants who ate the least meat had more than double the risk of dementia compared to those without the variants. The study also noted that a higher proportion of unprocessed meat in the diet was associated with a lower dementia risk for all participants, irrespective of APOE genotype.
Researchers hypothesize that the "food matrix" and nutrient delivery, potentially including vitamin B12, might play a role in these findings. While the study is observational and cannot definitively prove causation, it highlights the possibility that conventional dietary advice, often emphasizing plant-based foods, may not be optimal for everyone, particularly the APOE4 subgroup which accounts for many Alzheimer's cases.
