To determine if an older adult can meet their Dietary Reference Intakes (DRI’s) for selected vitamins and minerals and achieve an adequate macronutrient distribution range after being counseled on a high carbohydrate diet compared to those counseled on a low carbohydrate diet. <i>Methods</i>. Twenty six older adults were randomly selected into a high carbohydrate or low carbohydrate diet group. Both groups completed food records 5 days prior to intervention as well as during the 6 week time period they were following a high or low carbohydrate diet. Nutrition information was entered from written food records and analyzed using Minnesota Nutrition Data Systems for Research software. To determine the dietary adequacy of the high carbohydrate versus low carbohydrate diet groups, mean differences for weight, body mass index (BMI), fiber, calories, macronutrients and micronutrients were compared using Students’ t-tests for each nutrient at baseline, 3-weeks, and 6-weeks. An analysis of the group prevalence of inadequacy using the Estimated Average Requirement (EAR) cutoff point method was also completed. <i>Results</i>. There were no significant differences between groups for nutrient intake at baseline. The low carbohydrate group consumed greater amounts of fat and protein, while the high carbohydrate group consumed more calories and fiber during the 6-week study. At week 6 significant differences in intake of vitamin C, thiamin, niacin, vitamin B-6, folate, magnesium, iron, and potassium were observed between groups. Using the EAR cutoff, the prevalence of inadequacy of vitamin C, B-6, thiamin, niacin, folate, and magnesium was significantly higher in the low carbohydrate group compared to the high carbohydrate group. <i>Conclusion</i>. The results of this study suggest that a low carbohydrate diet (≤ 20 g) should not be recommended for the older adult for an extended period of time without proper supplementation. 2009-11-03 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1242742410 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1242742410 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
