Quality Diet Linked to Lower Dementia Risk in Older Adults, Study Finds

Eating a higher quality diet may significantly lower the risk of dementia in older adults, according to a new international study. The research indicates this benefit extends even to individuals whose blood biomarkers suggest they have an elevated biological risk for developing conditions like Alzheimer's disease.

The study, which included Slovenian researchers and was published in JAMA Network Open, highlights the protective role of diet in cognitive health. It suggests that adopting a dietary pattern with a lower inflammatory potential is associated with a reduced likelihood of dementia. This does not necessarily mean adhering to a rigid anti-inflammatory diet or following a list of forbidden foods.

Anja Mrhar, a nutrition master's student and first author of the study, explained that a better diet is linked to a lower risk of dementia. The research involved collaboration between the University of Ljubljana's Biotechnical Faculty, the University Medical Centre Ljubljana's Neurological Clinic (Center for Cognitive Disorders), and the Karolinska Institute in Stockholm. The findings underscore the importance of dietary choices in maintaining brain health as people age.

Higher quality nutrition is associated with a lower risk of dementia in older adults, even in those whose blood biomarkers indicate an increased biological risk for the development of the disease, including Alzheimer's disease.
