  • A 15-year study suggests that a low-inflammation diet is linked to a reduced risk of dementia, even with elevated Alzheimer's-related blood markers.
  • Nutritionist Xue Xiaojing recommends increasing vegetable, fruit, whole grain, fish, and soy intake while reducing processed foods and sugary drinks.
  • The study analyzed 1,865 elderly individuals in Sweden and found that better diet quality correlated with a later onset of dementia, particularly in those with higher risk markers.

A recent study indicates that adopting a diet with low inflammatory potential may still lower the risk of dementia, even for individuals showing elevated blood markers associated with Alzheimer's disease. The research, published in JAMA Network Open, tracked 1,865 community-dwelling seniors in Sweden over an average of 8.4 years.

low-inflammation diet is still associated with a lower risk of dementia and a later age of onset.

— Nutritionist Xue XiaojingXue Xiaojing shared findings from a study published in JAMA Network Open, highlighting the link between diet and dementia risk.

Researchers found that among participants with high levels of biomarkers like p-tau217 (linked to Alzheimer's pathology), NFL (indicating nerve cell damage), and GFAP (reflecting glial cell activation), a diet lower in inflammation was consistently associated with a reduced risk of dementia and a later age of onset. For every standard deviation increase in diet quality, the risk of dementia decreased by 21% to 29% for those with elevated biomarkers.

Dietary quality per standard deviation increase was associated with approximately 29% lower dementia risk for those with elevated p-tau217, 21% for NFL, and 27% for GFAP.

— Study findingsThe study quantified the association between improved diet quality and reduced dementia risk in high-risk individuals.

Nutritionist Xue Xiaojing, sharing the findings on her Facebook page, emphasized that these are statistical correlations and not direct proof of prevention or treatment. However, the study did observe that high-risk individuals with better dietary habits tended to develop dementia later. She suggests practical dietary adjustments for seniors, including increasing servings of vegetables, fruits, whole grains, fish, and soy products, while decreasing processed meats, sugary drinks, and highly processed foods. Specific advice includes starting meals with half a bowl of vegetables, consuming two servings of whole fruit daily, gradually incorporating whole grains into main meals, eating fish at least twice a week, and rotating soy products as a protein source. She also advises reducing the frequency of processed meats and sugary beverages, suggesting gradual changes rather than abrupt elimination.

These numbers represent statistical associations and cannot be directly interpreted as dietary changes preventing or treating dementia.

— Nutritionist Xue XiaojingXue Xiaojing cautioned against overstating the direct impact of diet on dementia prevention based solely on the study's correlational findings.
