Drug metabolism and disposition: the biological fate of chemicals·2010

Certain coffee brews contain diterpenes like cafestol and kahweol, which can temporarily increase cholesterol and triglycerides. Individuals at heart disease risk should choose coffee types low in these compounds.

Area of Science:

  • Cardiovascular Health
  • Hepatology
  • Nutritional Science

Background:

  • Coffee beans contain diterpenes, specifically cafestol and kahweol.
  • These compounds are present in unfiltered coffee brews, not those made with paper filters or instant coffee.
  • Diterpenes are known to have physiological effects in humans.

Purpose of the Study:

  • To investigate the health impacts of cafestol and kahweol found in coffee.
  • To assess the effects of coffee diterpenes on serum lipid levels and liver cell integrity.
  • To provide guidance for individuals at risk of heart disease regarding coffee consumption.

Main Methods:

  • Analysis of coffee bean composition for diterpene content.
  • Monitoring of serum cholesterol and triglyceride levels in human subjects.

  • Assessment of liver cell markers in relation to coffee consumption.

    • Main Results:

    • Unfiltered coffee brews contain cafestol and kahweol.
    • These diterpenes transiently elevate serum cholesterol and triglycerides.
    • Mild, transient effects on liver cell integrity were observed.
    • The association between lipid changes and liver effects remains unclear.

    Conclusions:

    • Coffee diterpenes (cafestol, kahweol) impact human lipid profiles and potentially liver health.
    • Effects are temporary upon cessation of diterpene intake.
    • Patients with elevated heart disease risk should opt for low-diterpene coffee preparations.
