The relationship between plasma ascorbate and lipid concentrations in fasting men

M L Burr, C J Bates, J E Milbank

    Human Nutrition. Clinical Nutrition
    |January 1, 1982
    PubMed
    Summary

    This study found that higher vitamin C levels in men were linked to lower total cholesterol and higher HDL cholesterol. These vitamin C (ascorbate) findings may be relevant for heart health.

    Area of Science:

    • Nutrition Science
    • Cardiovascular Health
    • Biochemistry

    Background:

    • Vitamin C (ascorbate) is an essential nutrient with antioxidant properties.
    • Plasma lipid profiles, including cholesterol and triglycerides, are key indicators of cardiovascular risk.
    • High-density lipoprotein (HDL) cholesterol is considered cardioprotective.

    Purpose of the Study:

    • To investigate the association between vitamin C status and plasma lipid concentrations.
    • To explore potential links between vitamin C and cardiovascular disease risk factors.

    Main Methods:

    • A study involving 97 healthy, fasting men.
    • Measurement of plasma ascorbate (vitamin C) levels.
    • Analysis of plasma lipid profiles: total cholesterol, HDL cholesterol, and triglycerides.

    Main Results:

    • Plasma ascorbate showed a significant negative association with total cholesterol (P < 0.05).
    • Plasma ascorbate demonstrated a significant positive association with HDL cholesterol concentration (P < 0.05).
    • A positive association was observed between plasma ascorbate and the HDL/total cholesterol ratio (P < 0.05).
    • No significant association was found between plasma ascorbate and triglyceride levels.

    Conclusions:

    • Vitamin C status may influence plasma lipid profiles in men.
    • The observed associations, particularly with HDL cholesterol, suggest potential clinical relevance for cardiovascular health.
    • Further research is warranted to confirm these findings and elucidate the underlying mechanisms.
