Affordability and Serving Accuracy of a Publicly Available DASH Meal Plan for Women Using SNAP Benefits

Background/Objectives: This regional case study evaluated the affordability and serving accuracy of a publicly available one-week DASH meal plan for single-woman households using Supplemental Nutrition Assistance Program (SNAP) benefits in central Kentucky. Methods: For each food item in the one-week plan, total grocery costs and per-serving costs were calculated using January 2025 prices from two national grocery chains commonly patronized in an urban area in central Kentucky. Calculated costs were compared to the average weekly food cost for women aged 20–50 years in a single household based on the Thrifty Food Plan (TFP). Servings for food groups and categories were calculated using MyPlate and American Heart Association guidelines to compare with those reported in the one-week plan. Results: The total grocery cost was $262.17, including staple foods expected to last more than a week. The adjusted per-serving cost of $82.90 was 21.19% higher than the average weekly food cost based on the January 2025 TFP. All food groups and categories except dairy showed differences of at least one serving between our calculations and the one-week plan. Conclusions: Findings from this case study on grocery costs suggest that the one-week plan may pose affordability challenges in this regional context and continued evaluation of whether SNAP benefit allotments based on TFP adequately reflect regional food cost variations may be warranted. Discrepancies in total servings highlight the need to improve the accuracy of publicly available DASH resources and to review these materials for consistency and accuracy.
