Primary Outcome Measures:
  • Measure of lipid panel including subfractions and Lp(a) and almond adherence [ Time Frame: Once a month ]

Secondary Outcome Measures:
  • Measurement of height, weight, waist circumference, blood pressure and physical activity [ Time Frame: Once a month ]

Enrollment: 50
Study Start Date: July 2008
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 2
Step 1 dietary counseling plus 100-110 grams of almonds daily
Dietary Supplement: Almonds
100-110 grams (about 3/4 cupful)of almonds consumed daily for 28 days
No Intervention: 1
Step 1 dietary counseling

Detailed Description:
The primary objectives of this study are to determine the changes in the lipid profile [LDL-C, HDL-C, triglycerides, total cholesterol], LDL-C particle size, and the emerging risk factor Lp(a) when 100-110 g of almonds daily are added to statin therapy. Also, all subjects will receive Step I dietary counseling.
