Abstract
This randomized controlled trial evaluated different cooking methods of potatoes as part of the DASH diet on blood pressure (BP) and anthropometrics in people with and without type 2 diabetes (T2D). Participants were randomized into DASH-FP (fried potatoes), DASH-NFP (non-fried potatoes) or DASH-NP (no potatoes) groups. BP, weight, waist circumference and body composition were measured.
Change outcomes from baseline to 6 weeks showed no significant difference in the study outcomes, including diastolic BP (p = 0.12), systolic BP (p = 0.26), body weight (p = 0.11), waist circumference (p = 0.86) and body composition (p = 0.57) within study groups. A significant group T2D status interaction was found for waist circumference (p = 0.036). Results from pairwise comparisons between the groups for all outcomes were not significant; however, a positive trend was seen in DASH-NFP and DASH-FP diet groups in BP and anthropometrics.
Individuals with and without T2D that consumed potatoes and the DASH diet did not significantly change BP and anthropometrics by six weeks. Slight improvements in BP and anthropometrics were seen in non-fried and fried potato groups. This helps future investigations of popular foods for people with chronic conditions that can be incorporated in a healthy eating pattern.
