Both hypertension and diabetes are so-called “silent killers.” We previously demonstrated the effect of a novel diet intervention program using COMpletely Balanced meal (COMB meal) consisting of 33 nutrient types on improving multiple parameters, including blood pressure and hemoglobin A1c (HbA1c). The present study evaluated the antihypertensive and antidiabetic effects of the program in an open-label randomized control trial. Trial 1 enrolled 100 males with high blood pressure (systolic blood pressure [SBP] ≥ 130 mmHg, and/or diastolic blood pressure [DBP] ≥ 85 mmHg). Trial 2 enrolled 99 males with HbA1c levels ≥ 5.6 %. Participants assigned to the test group took COMB meals every weekday for 4 weeks, replacing two meals per day. Compared to the control group, the test group showed significantly decreased DBP (p = 0.047) and HbA1c (p = 0.039). These results indicate that the novel program based on COMB meal might improve blood pressure and glucose metabolism through both nutrient supplementation and weight loss.
