Hypothesis
Does a soy drink enriched with plant sterols effectively lower cholesterol levels in individuals with moderate hypercholesterolemia?
Conclusion
Daily consumption of a plant sterol-enriched soy drink significantly decreased total, non-HDL, and LDL cholesterol.
Supporting Evidence
- LDL-C was reduced by 0.29 mmol/l or 7% compared to baseline.
- Total cholesterol decreased by 0.26 mmol/l.
- Non-HDL-C concentrations decreased by 0.31 mmol/l.
- Compliance was very high (>96%).
- The control group did not show significant changes in blood lipids.
Takeaway
Drinking a special soy milk with added plant stuff can help lower bad cholesterol in people with high cholesterol.
Methodology
A randomized, placebo-controlled double-blind study with 50 subjects consuming either a soy drink with or without plant sterols for 8 weeks.
Potential Biases
Potential bias due to self-reported compliance and satisfaction.
Limitations
The study was limited to a specific population and the effects of soy protein alone were not assessed.
Participant Demographics
50 subjects (19 men, 31 women) aged 19 to 65 years with moderate hypercholesterolemia.
