Area of Science:

  • Nutritional Science
  • Environmental Health

Background:

  • Selenium (Se) is a vital trace element for human and animal health.
  • The narrow range between essential and toxic levels necessitates careful dietary monitoring.
  • Geographical location significantly influences selenium status within populations.

Purpose of the Study:

  • To review the beneficial effects of selenium.
  • To report on existing studies of selenium status in various Saudi Arabian populations.
  • To identify gaps in current knowledge and suggest future research directions.

Main Methods:

  • Literature review of studies on selenium status in Saudi Arabia.
  • Analysis of geographical influences on selenium levels.
  • Synthesis of existing data to assess human selenium status.

Main Results:

  • Limited studies indicate geographical variations in selenium status among Saudi Arabian populations.
  • Current data on human selenium status in Saudi Arabia is scarce.
  • The review highlights the need for comprehensive selenium status assessments.

Conclusions:

  • Further research is crucial to fully understand human selenium status across Saudi Arabia.
  • Geographical factors play a role in selenium bioavailability and status.
  • Establishing baseline selenium levels is essential for public health and nutritional guidance.
