ABSTRACT
BACKGROUND:
Americans consume diets that fall short of dietary recommendations, and the cost of healthier diets is often cited as a barrier to dietary change. We conducted a nonrandomized crossover trial with meals provided utilizing 2 diets Dietary Approaches to Stop Hypertension (DASH) and whole food, plant-based (WFPB), and thus had intake data from baseline and both intervention diets.OBJECTIVES:
Using actual diet records, describe food costs of baseline diets of individuals with type 2 diabetes (T2DM) as well as therapeutic DASH and WFPB diets.METHODS:
Three-day food records were collected and analyzed for each 7-d diet phase baseline, DASH, and WFPB. Nutrient content was analyzed using the Nutrient Data System for Research and cost was determined using Fillet, an application to manage menu pricing. Food costs were calculated for each diet as consumed and adjusted to a standardized 1800 kcal/d. Ingredient-only costs of food away from home (FAFH) were approximated and analyzed. Costs were analyzed using linear mixed-effect models as a function of diet.RESULTS:
Fifteen subjects enrolled; 12 completed all dietary phases. The baseline, DASH, and WFPB diets, as consumed, cost $15.72/d (95% CI; $13.91, $17.53), $12.74/d ($11.23, $14.25), and $9.78/d ($7.97, $11.59), respectively. When adjusted to an 1800 kcal/d intake, the baseline, DASH, and WFPB diets cost $15.69/d ($13.87, $17.52), $14.92/d ($13.59, $16.26), and $11.96/d ($10.14, $13.78), respectively. When approximated ingredient-only costs of FAFH were analyzed, as consumed baseline [$11.01 ($9.53, $12.49)] and DASH diets [$11.81 ($10.44, $13.18)] had similar costs; WFPB diet [$8.83 ($7.35, $10.31)] cost the least.CONCLUSIONS:
In this short-term study with meals provided, the food costs of plant-predominant diets offering substantial metabolic health benefits were less than or similar to baseline food costs of adults with insulin-treated T2DM. Longer-term data without meal provision are needed for more generalizable results. This trial was registered at clinicaltrials.gov as NCT04048642.Palavras-chave
