Supplementing with selenium-enriched bread significantly improved whole blood selenium levels in volunteers with suboptimal selenium status. This dietary intervention offers a simple and effective method for enhancing selenium levels.

Area of Science:

  • Nutritional biochemistry
  • Human physiology
  • Food science

Context:

  • Selenium is an essential trace element crucial for various physiological functions.
  • Suboptimal selenium status is a widespread nutritional concern.
  • Dietary strategies are needed to improve selenium bioavailability.

Purpose:

  • To evaluate the efficacy of selenium-enriched bread in improving whole blood selenium concentrations.
  • To assess the impact of a short-term supplementation period on selenium status.

Summary:

  • Ten volunteers with suboptimal selenium status consumed bread fortified with selenium-enriched yeast (approx. 100 µg selenium daily).
  • Whole blood selenium levels increased significantly from a mean baseline of 52.2 ± 16.7 µg/l to 66.1 ± 11.9 µg/l after two weeks.
