Alfalfa seeds: effects on cholesterol metabolism
Experientia
|May 15, 1980
Summary
Alfalfa seeds (AS) consumption lowered plasma cholesterol in humans and rats. Studies showed AS reduced cholesterol absorption and increased its excretion, with no signs of toxicity observed.
Area of Science:
- Nutritional Science
- Biochemistry
- Toxicology
Background:
- Elevated plasma cholesterol is a significant risk factor for cardiovascular diseases.
- Dietary interventions are crucial for managing cholesterol levels.
Purpose of the Study:
- To investigate the effects of alfalfa seeds (AS) on plasma cholesterol concentrations in humans and rats.
- To assess the safety and potential toxicity of AS consumption.
Main Methods:
- Human volunteers ingested diets containing AS for 3 weeks.
- Rats were fed AS to evaluate effects on cholesterol metabolism.
- Serum parameters were analyzed to detect toxicity.
Main Results:
- Plasma cholesterol levels were reduced in human volunteers.
- AS ingestion in rats decreased plasma cholesterol.
- AS reduced intestinal cholesterol absorption and increased fecal biliary excretion.
- No signs of toxicity were observed in human serum analyses.
Conclusions:
- Alfalfa seeds demonstrate a cholesterol-lowering effect in both humans and rats.
- AS may be a safe and effective dietary component for managing hypercholesterolemia.
