Anti-inflammatory diet shown to reduce dementia risk
A new study indicates that adhering to an anti-inflammatory diet can significantly lower the risk of developing dementia, especially in individuals who may already be at heightened biological risk. The research, published in the journal JAMA Network Open, tracked over 1,800 adults aged 60 and older in Sweden over a period of up to 15 years, reports BritPanorama.
Participants, who did not have dementia at the outset, completed detailed food questionnaires and had their blood checked for markers associated with Alzheimer’s disease. During the follow-up, 240 participants were diagnosed with dementia. Notably, those whose diets exhibited lower inflammatory potential were considerably less likely to develop the condition, even among those with high levels of Alzheimer’s-related biomarkers.
Specifically, individuals with elevated p-tau217 levels who adhered closely to an anti-inflammatory diet had a 29% lower risk of dementia. Similar reductions were observed for participants with other biomarkers related to nerve cell injury and inflammation. This suggests that dietary choices can have a significant impact on brain health.
Dr. Leana Wen, an emergency physician and clinical associate professor, explained that an anti-inflammatory diet is not a single plan but rather a guiding principle emphasizing whole, minimally processed foods, which includes a high intake of fruits, vegetables, nuts, and whole grains while limiting added sugars and ultraprocessed products.
Research findings reflect the importance of dietary patterns not only for reducing dementia risk but also for preventing other chronic diseases, such as heart disease and type 2 diabetes. Wen cautioned, however, that while the observational nature of the study provides valuable insights, it doesn’t establish a direct cause-and-effect relationship.
This high-quality longitudinal study reinforces the idea that individuals can make lifestyle adjustments that potentially mitigate risk factors for dementia. Emphasizing dietary changes as sustainable habits rather than quick fixes may foster better health outcomes over time. The ongoing conversation around healthy eating continues to highlight a landscape of increasing evidence regarding nutrition’s pivotal role in maintaining cognitive function.
As research evolves, the narrative around brain health increasingly underscores the necessity of a holistic approach to diet and lifestyle, suggesting pathways for healthier aging.
