Evaluation of the effect of iron, zinc and selenium on metabolic processes in viral diseases

The deficiency of macro- and microelements and the disturbance of their balance are widely recognized issues in healthcare, with poor nutrition exacerbating disruptions in metabolic processes at both the cellular and organismal levels. All these metabolic circumstances and disruptions in metabolic processes contribute to the development of various pathological conditions, including viral infections. Macro- and microelements play a crucial role in many metabolic processes that affect the course of infectious diseases. These processes include oxidative phosphorylation, which is altered in patients with systemic inflammation and protection against mediators, including oxidants. Microelements are necessary for direct antioxidant activity and also function as cofactors for various antioxidant enzymes. Immune function also depends on an adequate level of vitamins and microelements. It can be enhanced by restoring microelement deficiencies to recommended levels, thereby increasing resistance to infection and promoting faster recovery after infection. Balanced nutrition alone is insufficient, hence the need for the supplementation of microelements tailored to specific age-related requirements. In this article, we explore the importance of the optimal balance of individual macro- and microelements for effectively combating viral infections.
