Evaluation of Soybean Peptides Product on Regulation of Blood Pressure Effect in Humans

This is the report to assess supplementation with soybean peptides on blood pressure among people with mild hypertension. Thirty subjects with systolic blood pressure (SBP) between 120 and 159 mm Hg and/or diastolic blood pressure (DBP) between 80 and 99 mm Hg were randomized to ingest 2 bags of soybean peptides or placebo per day for 8 weeks of a stage. Anthropometric measurements (blood pressure, body weight, body fat) and blood biochemical markers including fasting blood glucose (FBG), albumin, total cholesterol (TC), triglyceride (TG), HDL-C, LDL-C, creatinine (Cr), blood urea nitrogen (BUN), AST, ALT) were examined every four weeks.

Inclusion criteria

• Eligible subjects were untreated hypertensive men or women aged between 20 and 80 years old with SBP between 120 and 159 mmHg and/or DBP between 80 and 99 mmHg as measured in a sitting position

Exclusion criteria

• Subjects were excluded if they had a history of major cardiovascular disease or severe liver dysfunction;
• Diastolic blood pressure ≥ 100 mmHg or Systolic blood pressure ≥ 160 mmHg;
• Alcoholic;
• US-controlled diabetics;
• Stoke in past one year;
• Mental diseases or melancholia;
