Anti-Inflammatory Diet Linked to 29% Lower Dementia Risk in Adults With Alzheimer’s Biomarkers

Summary
A 1,865-person study of adults 60 and older found that a more anti-inflammatory diet was tied to lower dementia risk even among people with elevated Alzheimer’s-related blood biomarkers.
Among participants with higher p-tau217 levels, stronger adherence to the anti-inflammatory pattern was associated with a 29% lower dementia risk; similar reductions appeared with biomarkers tied to nerve-cell damage and inflammation.
All three healthy diet patterns studied were linked to lower dementia risk mainly in people with lower biomarker levels, suggesting anti-inflammatory eating may remain beneficial later in the disease process.
The Swedish study followed participants for up to 15 years and repeatedly assessed diet, but as an observational analysis published in JAMA Network Open, it cannot prove diet directly prevented dementia.

Anti-Inflammatory Diet Linked to Lower Dementia Risk: Landmark Swedish Study and Practical Brain Health Strategies
Overview
A major Swedish study published in 2026 found that older adults who follow an anti-inflammatory diet have a lower risk of developing dementia and tend to experience the disease later in life. The research used the dietary inflammatory index to measure how eating patterns affect inflammation and showed that even people with early biological signs of Alzheimer’s disease benefited from this diet. These findings highlight that adopting a diet with lower inflammatory potential can help protect brain health, offering hope for dementia prevention even among those already at higher risk.
