Study Links Anti-Inflammatory Diet to 21%-29% Lower Dementia Risk in High-Biomarker Adults

Summary
Among 1,865 older adults tracked for 15 years, 240 developed dementia, with lower rates seen in those whose diets scored higher on an anti-inflammatory index.
Higher anti-inflammatory diet scores were tied to 21% to 29% lower dementia risk in people with elevated Alzheimer’s biomarkers including p-tau217, NFL and GFAP.
The Mediterranean-style diet also showed protective effects, but only among participants with lower baseline biomarker levels, suggesting diet benefits may differ by underlying pathology.
Researchers used Swedish SNAC-K cohort data and a 98-item food questionnaire, but said the observational design cannot prove that changing diet prevents dementia or slows Alzheimer’s progression.
The findings add to evidence that long-term diet quality—especially patterns rich in vegetables, fruits, legumes, whole grains and healthy fats—may support brain health alongside cardiometabolic benefits.

Overview
Groundbreaking research led by Anja Mrhar and colleagues from Karolinska Institutet and Stockholm University has provided strong observational evidence that anti-inflammatory diets are linked to a lower risk of cognitive decline and dementia. This study marks a major advance in understanding how what we eat can influence dementia risk. The researchers used a comprehensive dietary assessment and found that people who consistently followed diets low in inflammation had the most pronounced protective effects. As blood-based Alzheimer’s tests become more accurate and accessible, identifying effective prevention strategies like these diets is becoming increasingly important.
