Diet and high density lipoproteins

P Oster, G Schlierf, C C Heuck

    Lipids
    |February 1, 1981
    PubMed
    Summary

    Dietary changes can acutely alter high density lipoprotein (HDL) cholesterol in healthy individuals but struggle to raise low HDL levels in patients. Further research is needed to understand HDL

    Area of Science:

    • Cardiovascular disease
    • Nutritional science
    • Lipid metabolism

    Background:

    • High density lipoprotein (HDL) cholesterol is a key factor in cardiovascular health.
    • Dietary interventions are explored for managing lipid profiles.
    • Understanding HDL's response to diet is crucial for preventing vascular disease.

    Purpose of the Study:

    • To investigate the acute and subacute effects of various diets on serum HDL cholesterol and HDL composition.
    • To assess the impact of dietary interventions on HDL levels in different patient groups (obese, hyperlipidemic) and healthy individuals.

    Main Methods:

    • Observational study analyzing serum HDL cholesterol and composition.
    • Comparison of different dietary regimens (total starvation, prudent diets, high-carbohydrate, high-fat diets).
    • Evaluation in normolipemic, hypercholesterolemic (type II), hypertriglyceridemic (type IV) patients, and healthy volunteers.

    Main Results:

    • Total starvation for 2 weeks did not increase low HDL cholesterol in obese or hyperlipidemic patients.
    • Prudent diets showed no significant effect on HDL cholesterol in type II and IV hyperlipoproteinemia patients within 3 weeks.
    • In healthy individuals, a high-carbohydrate diet decreased HDL cholesterol and increased HDL triglycerides compared to a high-fat diet.
    • HDL triglyceride fatty acid composition varied in healthy volunteers based on ingested fat type.

    Conclusions:

    • Acute dietary changes can manipulate HDL in healthy individuals.
    • Normalizing low HDL cholesterol levels in patients through diet is challenging.
    • More research on HDL function is needed before evaluating therapeutic manipulation for preventing ischemic vascular disease.
