Is Maternal Selenium Status Associated with Pregnancy Outcomes in Physiological and Complicated Pregnancy?

Selenium is essential for the synthesis and function of various selenoenzymes, such as glutathione peroxidases, selenoprotein P, and thioredoxin reductase. These enzymes play a critical role in both antioxidant defense and in limiting oxidative damage. Numerous studies have reported associations between serum selenium concentration, obstetric complications and pregnancy outcomes.

Hypersensitivity Reactions to Food Additives-Preservatives, Antioxidants, Flavor Enhancers.

There have been reports of food hypersensitivity reactions to food additives (HFA) for many years. The mechanisms of HFA and their frequency are difficult to precisely define, as most of the data come from outdated studies with poor methodology. In 2020, the European Food Safety Authority completed a review of additives, examining their influence on the occurrence of HFA, but did not include all of them.
