To our knowledge, no study has fed volunteers the current Dietary Guidelines for Americans diet pattern (DGA) evaluating its effect on CVD risk factors. This study assessed the effects of DGA, a Korean diet (KD) and a typical American diet (TD) on lipid profile and blood pressure (BP) in overweight, non‐Asian individuals with elevated LDL‐C. The study was a 3‐period crossover, controlled‐feeding study. Subjects were randomly allocated to 1 of 6 possible sequential orders for consuming the 3 diets for 4 weeks, separated by a 10‐day break. Subjects remained weight‐stable. Lipid profile, BP, insulin, glucose, and 24‐hr urinary sodium were determined at baseline and at the end of each diet period. Total cholesterol and LDL‐C significantly decreased on KD and DGA but not on TD. HDL‐C significantly decreased on all three diets. No diet had a significant effect on serum triglycerides, but an upward trend on KD and a downward trend on DGA resulted in a significant difference between these two diets. All three diets caused modest decreases in systolic and diastolic BP, which reached statistical significance only for DGA. No diet had significant effect on fasting insulin, whereas fasting glucose decreased significantly on KD and TD only. Urinary sodium output decreased significantly on DGA. In conclusion, after a 4‐week feeding period, KD and DGA patterns resulted in positive changes in CVD risk factors. Supported by RDA & USDA/ARS
