Study Description

Brief Summary:

The current research study has the potential to generate data that would provide solid clinical endpoints as to the impact of including eggs in a regular diet in individuals with peripheral arterial disease. Any one of three potential outcomes may be observed as a result of this study, and they are predicted as follows: 1) Egg consumption does not lead to a deterioration of indices of cardiovascular health; 2) Egg consumption improves indices of cardiovascular health; 3) Egg consumption worsens the indices of cardiovascular health.

Condition or disease	Intervention/treatment	Phase
Peripheral Arterial Disease	Other: Classic Egg Group Other: Omega 3 Egg Group	Not Applicable

Detailed Description:

Given the hypotheses proposed, if either of the first two predictions prove to be positive, they will help encourage directive efforts to be made toward effective nutrition messages for egg consumption in the peripheral arterial disease and the healthy population. If the last prediction is positive, while least favourable, it will still establish important information to assist the industry in their efforts toward establishing population-specific nutrition messaging.

Arms and Interventions

Arm	Intervention/treatment
No Intervention: Control Group no shell egg consumption and usual dietary practices
Active Comparator: Classic Egg Group consumption of 6 eggs/week (1 egg/day for 6 days with 1 day rest) of commercial classic eggs	Other: Classic Egg Group consumption of 6 eggs/week (1 egg/day for 6 days with 1 day rest) of commercial classic eggs
Active Comparator: Omega 3 Egg Group consumption of 6 eggs/week (1 egg/day for 6 days with 1 day rest) of commercial Omega-3 eggs	Other: Omega 3 Egg Group consumption of 6 eggs/week (1 egg/day for 6 days with 1 day rest) of commercial Omega-3 eggs

Outcome Measures

Primary Outcome Measures :

Establish quantitative and qualitative data on the dietary patterns, including egg consumption, in patients with PAD [ Time Frame: change in assessments from baseline to 8 weeks ]
The following assessments are included to measure the primary outcome:

1)Anthropometrics: weight, height; waist circumference, Body Mass Index; 2)Dietary Assessment:3-day dietary food record, food frequency questionnaire (baseline only); 3)Biochemical Analyses; 4)Expression and Metabolic Profiling; 5)Arterial Compliance: Ankle-brachial index, pulse wave velocity, arterial vasodilation, and advanced glycation endproducts; 6) Semi-structured interview.

Secondary Outcome Measures :

Determine the impact of consuming 6 eggs per week on primary end-points and other modifiable risk factors in patients with PAD. [ Time Frame: change in assessments from baseline to 8 weeks ]
The following assessments are included to measure the primary outcome:

1)Anthropometrics: weight, height; waist circumference, Body Mass Index; 2)Dietary Assessment:3-day dietary food record, food frequency questionnaire (baseline only); 3)Biochemical Analyses; 4)Expression and Metabolic Profiling; 5)Arterial Compliance: Ankle-brachial index, pulse wave velocity, arterial vasodilation, and advanced glycation endproducts; 6) Semi-structured interview.
