  • Data are means ± SE.

  • *The control diet was a designed to control diabetes. The general recommendation for macronutrient composition of the diet was 50–60% carbohydrates; 15–20% protein and <30% total fat. The amount of simple sugar was less than 5% of calorie intake.

  • †The DASH diet was rich in fruits, vegetables, whole grains, and low-fat dairy products, and low in saturated fat, total fat, cholesterol, refined grains, and sweets. The amount of sodium intake was 2,400 mg per day.

  • P values are for comparisons between the two diet periods (general linear model). DBP, diastolic blood pressure; FBG, fasting blood glucose; HDL-C, HDL cholesterol; LDL-C, LDL cholesterol; SBP, systolic blood pressure; TG, triglyceride.
