Several aspects of the diet appear theoretically useful in preventing most urinary tract calculi, and its efficacy should indeed be investigated. The DASH diet is, however, multi-faceted, complex, and quite different from the diets of many stone formers; compliance may be an issue. We piloted a modified DASH diet to identify difficulties and challenges in compliance when applied to patients in the clinical setting. METHODS We recruited healthy, compliant women (n=25; age 38±17 y; BMI 23.3±2.8) from the university community to follow a modified DASH diet for 10 days. The diet incorporated a high fluid and low oxalate intake but was otherwise identical to the traditional DASH diet. Each subject was provided a diet template that defined food categories, serving sizes, and target servings/d, and used a food scale to complete 4-day, weighed diet records. RESULTS 118 days of diet records were evaluated. Subjects were compliant with respect to avoidance of the 8 high-oxalate foods that were identified at enrollment (data not shown) and also in achieving fluids of 3.33 L/d. Subjects were, however, non-compliant related to suboptimal daily servings of fruit, vegetables, whole grains, and dairy, and out of compliance with the strict sodium restriction of the DASH diet (see figure). Though subjects reported understanding the DASH diet instructions provided at recruitment and confirmed a willingness to follow it, practical strategies to achieve good compliance were lacking. CONCLUSIONS The DASH diet is modifiable with respect to urolithiasis prevention. However, compliance, even among willing participants, appears difficult, perhaps owing to the complexity of the diet but also to deficits in strategic knowledge with respect to application. Specific instruction and teaching materials should be developed. © 2012 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 187Issue 4SApril 2012Page: e907 Advertisement Copyright & Permissions© 2012 by American Urological Association Education and Research, Inc.MetricsAuthor Information Kristina L.
