The Mediterranean-Dietary Approach to Stop Hypertension (DASH) Intervention for Neurodegenerative Delay (MIND) diet is a dietary pattern designed to prevent cognitive decline. Dietary adherence is assessed with the MIND diet scoring system, which is currently based on the American diet and serving sizes. It is known that serving sizes and consumed food products differ between countries. Existing literature lacks reporting on food products included within the MIND diet and weight or volume equivalents corresponding to MIND diet servings, impeding accurate comparisons across studies. This study sought to overcome these limitations by evaluating MIND food products consumed in the Dutch context and developing a scoring system based on consumed quantities in weight or volume amounts rather than in standard serving amounts. The third objective was to modify an existing Dutch brief FFQ (Eetscore-FFQ) to evaluate adherence to the MIND diet. We translated nine of the fifteen MIND food groups directly to grams and volumes using the United States Department of Agriculture measurement conversion table. For the remaining food groups, we employed indirect translation to align them as closely as possible to the original MIND diet. These translated quantities in weight and volumes amounts were subsequently rounded to the nearest Dutch household measures, resulting in the culturally adapted MIND-NL diet scoring. The development of the MIND-NL-Eetscore-FFQ, comprising seventy-two food items (forty-one questions), is described. Our adaption approach is reproducible and can be used to customize the MIND diet scoring system to other cultures.
