Dachundou No Sugar Added Soymilk for Lipid Modulation

Overview

Cardiovascular disease is one of the leading causes of death worldwide, and high cholesterol is a major risk factor. Diet is known to play an important role in managing blood lipids. Soy milk is a common plant-based drink rich in protein and isoflavones, which may help lower cholesterol and improve heart health. This clinical trial will evaluate whether daily consumption of Dachundou No Sugar Added Soymilk can help reduce cholesterol levels in adults with elevated total cholesterol (≥200 mg/dL). A total of 50 participants aged 18-65 will be recruited. Participants will drink two bottles of soymilk per day (375 mL each, total 750 mL) for 8 weeks. During the study, researchers will measure cholesterol, blood pressure, body weight, waist circumference, and other health indicators. The results will help determine whether Dachundou No Sugar Added Soymilk can improve blood lipid levels and contribute to cardiovascular health.

Cardiovascular disease remains a leading cause of morbidity and mortality worldwide, with dyslipidemia being one of the most important risk factors. Dietary interventions, such as plant-based proteins and bioactive compounds, have been shown to improve lipid profiles and reduce cardiovascular risk. Soy milk is widely consumed in Asia and contains soy protein and isoflavones, which have antioxidant, anti-inflammatory, and lipid-regulating effects. Previous studies suggest that soy protein may lower total cholesterol and LDL-C through inhibition of HMG-CoA reductase and upregulation of LDL receptor expression, while soy isoflavones may enhance lipid metabolism and endothelial function through estrogen-like actions. This trial aims to evaluate the lipid-lowering efficacy of Dachundou No Sugar Added Soymilk in adults with fasting total cholesterol ≥200 mg/dL. A total of 50 participants, aged 18-65 years, non-smokers, without alcohol abuse, and otherwise healthy, will be enrolled. All participants will consume two bottles of soymilk per day (375 mL each; total 750 mL) for 8 consecutive weeks. Assessments will be performed at baseline (week -2 and week 0), during the intervention (week 4 and week 8), and post-intervention (week 10). Measurements include anthropometrics (height, weight, waist circumference, blood pressure), blood biochemistry (lipid profile, glucose, liver and kidney function), oxidative stress (oxidized LDL via TBARS), and lifestyle factors (dietary records and physical activity questionnaires). The primary outcome is the change in total cholesterol from baseline to week 8. Secondary outcomes include changes in LDL-C, HDL-C, triglycerides, oxidized LDL, liver/kidney function, and anthropometric indices. The findings will provide evidence on whether Dachundou No Sugar Added Soymilk can serve as a dietary intervention to improve blood lipid levels and promote cardiovascular health.
