BACKGROUND AND OBJECTIVES: Sichuan cuisine is characterized by high salt and oil content. We aimed to evaluate the effects of the Sichuan cuisine version of Chinese heart-healthy diet (CHH diet-SC) on blood pressure reduction among hypertensive adults.
METHODS AND STUDY DESIGN: The Chinese heart-healthy diet (CHH) trial was a multicenter randomized controlled feeding trial among Chinese hypertensive people. We conducted a secondary analysis of the CHH trial using data from the Sichuan center in Southwest China. Fifty-three people aged 25 to 75 years with a mean systolic blood pressure (SBP) between 130 and 159 mmHg were enrolled. Eligible participants underwent a 1-week run-in period with the typical local diet and were randomized 1:1 to consume the CHH diet-SC (n=27) or typical local diet (n=26) for the next 4-week. The primary outcome was the net change in SBP, the secondary outcomes included diastolic blood pressure (DBP), mean arterial pressure (MAP), and the rate of BP control.
RESULTS: Compared with the control group, the CHH diet-SC decreased cooking salt, oil, and red meat content and increased inclusion of whole grains, fruits, seafood, low-fat dairy, soybean, and nuts; the SBP experienced reductions of 7.54, 8.60, 9.14, and 10.1 mmHg at the end of weeks 1 through 4; the DBP was reduced 4.01 mmHg at week 4; the MAP was significantly reduced 6.02 mmHg finally; and rate of BP control significantly increased (p<0.05).
CONCLUSIONS: Adoption of the CHH diet-SC for 4 weeks can significantly reduce BP and increase the rate of BP control in hypertensive adults.
