Adjusted for age, race, DDE fat, carb, protein, smoking status, BMI, blood CRP, total cholesterol, triglycerides, LDL-C, HDL-C, glucose and insulin. DBP, diastolic blood pressure; SBP, systolic blood pressure; DDE, daily dietary estimate; BMI, body mass index. CRP, C-reactive protein; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol.
