Meat consumption linked to lower Alzheimer's risk
A major recent study indicates that increased meat intake may protect against dementia, but the benefit applies specifically to individuals with higher genetic predisposition rather than everyone. Researchers observed slower cognitive decline among those who consumed more protein-rich foods while carrying elevated risks for developing Alzheimer's disease in their DNA profile. Experts caution readers not to adopt a carnivore diet indiscriminately as this protective effect is limited to select groups of people only.
Key Points
-
1A major study suggests that increased meat consumption may reduce the risk or slow cognitive decline associated with dementia.
-
2However, these protective benefits appear to apply specifically only to adults who have a higher genetic predisposition for Alzheimer's disease rather than everyone generally.
-
3Experts warn against adopting extreme carnivore diets based on this research as it is not recommended advice suitable for all populations.
Developments
A major Swedish study found that adults with high-risk APOE gene variants who consumed five or six large portions of unprocessed meat weekly experienced slower cognitive decline and lower dementia risk. Conversely, those in the same genetic group eating less than this amount were more than twice as likely to develop dementia compared to non-carriers.
New research indicates that individuals carrying high-risk genetic variants for Alzheimer's disease may experience slowed cognitive decline when consuming approximately 870 grams (roughly one steak) or more per week. This protective effect was not observed in the general population, suggesting meat-heavy diets benefit only those with specific gene combinations like APOE ε4/ε3-epsilon2 and epsilon5-carriers who are at higher risk for dementia without these genetic markers
