[Selenium supplementation with bread]
Abstract:
Bread produced with selenium-enriched yeast was given to ten volunteers. The daily dose contained approximately 100 micrograms of selenium. The subjects' mean baseline whole blood selenium concentration (52.2 +/- 16.7 micrograms/l) was indicative of a suboptimal selenium status. After two weeks of supplementation, the subjects' mean whole blood selenium level increased significantly (to 66.1 +/- 11.9 micrograms/l). Supplementation of selenium-enriched bread seems to be an easily implementable and promptly acting method of selenium status improvement.

Overview of Metabolism
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
