Inflammation-Lowering Diet Slashes Dementia Risk
26 Jun
Summary
- Healthy diets linked to lower risk of Alzheimer's and dementia.
- Anti-inflammatory diets reduce dementia risk for high-risk individuals.
- Diet quality may influence if and when dementia develops.
A new study published in JAMA Network Open suggests a link between diet quality and a reduced risk of dementia. Researchers found that older adults who adhered to diets with lower inflammatory potential experienced a decreased likelihood of developing dementia. This research, utilizing data from the Swedish National study on Aging and Care in Kungsholmen (SNAC-K), followed participants aged 60 and over for up to 15 years.
The study specifically highlighted that for individuals with elevated Alzheimer's biomarkers, a higher adherence to an inflammation-lowering diet correlated with a 21% to 29% lower dementia risk. While a Mediterranean-style diet showed benefits for those with lower baseline biomarker levels, the anti-inflammatory diet appeared more impactful for individuals at higher genetic risk.
Experts emphasize that while diet cannot reverse existing Alzheimer's pathology, it may help improve brain resilience and potentially delay the onset of symptoms. The findings suggest that reducing inflammatory burden in the body could positively influence brain health through the gut-brain-immune axis. Further research is ongoing to fully understand these complex relationships.
