This is a single site, open registration, dietary proof of concept, food substance study designed to explore the health benefits associated with daily pulse consumption in individuals with peripheral arterial disease. The investigators hypothesis that a diet containing at least one serving of pulse crops (dried beans, peas, lentil, chickpeas) per day provides flavonoid compounds that improve cardiovascular health by increasing the levels of serum adiponectin is based on evidence from the literature that indicates flavonoids present in these foods are capable of improving arterial stiffness and reducing hypercholesterolemia.

Primary Outcome Measures:
  • Identification of changes in endothelial function in response to dietary modification [ Time Frame: baseline, week 8 ] [ Designated as safety issue: No ]
  • Correlation of serum adiponectin levels [ Time Frame: baseline, week 8 ] [ Designated as safety issue: No ]
  • Correlation of changes in endothelial cell function with serum isoflavone levels [ Time Frame: baseline, week 8 ] [ Designated as safety issue: No ]
  • Genetic Profiling [ Time Frame: baseline, week 8 ] [ Designated as safety issue: No ]
  • Analysis of serum and urinary eicosanoids [ Time Frame: baseline, week 8 ] [ Designated as safety issue: No ]
  • Serum analysis for fatty acid composition [ Time Frame: baseline, week 8 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Descriptive analysis of clinical data: Demographics, medical history, [ Time Frame: baseline ] [ Designated as safety issue: No ]
  • Physical findings, concomitant medications and adverse events [ Time Frame: baseline, weekly for 8 weeks ] [ Designated as safety issue: Yes ]
  • Qualitative analysis of data collected from semi-structured subject interviews [ Time Frame: week 1, week 2, week 4, week 6, week 8 ] [ Designated as safety issue: No ]
  • (Compliance/tolerability/side effects) [ Time Frame: week 1, week 2, week 4, week 6, week 8 ] [ Designated as safety issue: Yes ]
