Brief Summary:
The purpose of the study is to evaluate the effects of 100-110 grams of almonds (about ¾ cupful) daily on the lipoprotein profile when given to patients on a statin drug. The study will compare the effects on the lipoprotein profile to patients who eat almonds and those patients not eating almonds.

Condition or disease Intervention/treatment Phase
Hyperlipidemia Dietary Supplement: Almonds Phase 4

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.
