One thousand nine hundred forty-three (6.9%) were diagnosed with dementia (median follow-up, 19.8 years). Individuals adhering to conventional dietary recommendations did not have lower risk of developing all-cause dementia (hazard ratio [HR] comparing worst with best adherence, 0.93, 95% CI 0.81–1.08), AD (HR 1.03, 0.85–1.23), or VaD (HR 0.93, 0.69–1.26). Neither did adherence to the modified Mediterranean diet lower the risk of developing all-cause dementia (HR 0.93 0.75–1.15), AD (HR 0.90, 0.68–1.19), or VaD (HR 1.00, 0.65–1.55). The results were similar when excluding participants developing dementia within 5 years or those with diabetes. No significant associations were found between diet and abnormal Aβ accumulation, conventional recommendations (OR 1.28, 0.74–2.24) or modified Mediterranean diet (OR 0.85, 0.39–1.84).Discussion In this 20-year follow-up study, neither adherence to conventional dietary recommendations nor to modified Mediterranean diet were significantly associated with subsequent reduced risk for developing all-cause dementia, AD dementia, VaD, or AD pathology.Aβ=AD-related β-amyloid; AD=Alzheimer disease; FFQ=food frequency questionnaire; mMDS=modified Mediterranean diet score; IQR=interquartile range; METhh/week=metabolic equivalent hours/week; NPR=National Patient Register; PREDIMED=Prevención con Dieta Mediterránea; SDGS=Swedish dietary guidelines score; VaD=vascular dementia
