Analysis Of Nutritional Habits And Intake Of Polyunsaturated Fatty Acids In Veterans With Peripheral Arterial Disease

Inadequate nutrient intake may contribute to the development and progression of peripheral arterial disease (PAD). This study's aim was to assess intake of essential fatty acids and nutrients among veterans with PAD. All 88 subjects had ankle-brachial indices of <0.9 and claudication. A validated food frequency questionnaire evaluated dietary intake, and values were compared to guidelines established by the American Heart Association (AHA) and American College of Cardiology (ACC), as well as the AHA/ACC endorsed Dietary Approaches to Stop Hypertension (DASH) eating plan. The mean age was 69 +/- 8 years. Compared to the AHA/ACC guidelines, subjects with PAD had an inadequate intake of long-chain polyunsaturated fatty acids (n-3 PUFA; 59% consumed >1 gram daily). Our subjects with PAD had an increased intake of cholesterol (31% met the cut-off established in the DASH plan), total fat (5%) and sodium (53%). They had an inadequate intake of magnesium (3%), calcium (5%), and soluble fiber (3%). Dietary potassium intake met the recommended guidelines. In our subjects with PAD, intake of critical nutrients deviated substantially from the recommended amounts. Further prospective studies should evaluate whether PAD patients experience clinical benefit if diets are modified to meet the AHA/ACC recommendations.
