US EditionEating more meat may lower Alzheimer’s risk for some people
Researchers found the association only in APOE 3/4 and 4/4 carriers, while low-meat eaters with those genotypes had more than twice the dementia risk.
- A new study from Karolinska Institutet published in JAMA Network Open found that higher meat intake is associated with slower cognitive decline for older adults carrying APOE 3/4 or 4/4 gene variants.
- Lead author Jakob Norgren hypothesized that APOE4 carriers might benefit from meat because the gene variant is evolutionarily oldest, potentially arising when ancestors relied on animal-based diets.
- Tracking 2,157 participants aged at least 60 for up to 15 years, researchers found that APOE carriers consuming more meat showed significantly slower cognitive decline than those eating less.
- Neurologist Aviva Lubin cautions that most patients evaluated for dementia are not tested for APOE genotypes, making clinical application of findings difficult without further trials.
- While findings offer hope for modifiable risk, researchers suggest conventional dietary advice may be unfavourable to this genetically defined subgroup, necessitating more research before clinical recommendations.

A Swedish study shows that those who are more genetically susceptible to dementia can clearly reduce their risk through higher meat consumption.
A new study from Sweden reveals surprising things: In certain cases, high meat consumption can reduce the risk of dementia. What about it?
Eating more meat may lower Alzheimer’s risk for some people
A surprising new study suggests that genetics may change how diet affects brain health—especially when it comes to Alzheimer’s risk. Researchers found that older adults carrying high-risk APOE gene variants didn’t show the expected cognitive decline if they ate relatively high amounts of meat. In fact, those with these genes who consumed the most meat had slower cognitive decline and lower dementia risk, challenging conventional dietary advice.
Why eating meat may reduce Alzheimer’s risk for some people
Scientists are beginning to understand that the same diet may not work the same way for everyone. A new study from Karolinska Institutet, published in JAMA Network Open, shows that people with a higher genetic risk of Alzheimer’s disease may benefit from eating more meat, while others may not see the same effect.
