How Can Cancer-Associated Anemia Be Moderated with Nutritional Factors and How Do Beta Vulgaris L. Ssp. Esculenta Var. Rubra Modify the Transmethylation Reaction in Erythrocytes in Cancerous Patients?

Genetic predisposition, unhealthy dietary or life habits and heavy social circumstances could result in the changes of redox homeostasis, which is very important for the equilibrium between tissue regeneration and apoptosis. When the balance is disturbed, cancer and/or necrosis may develop (Powis et al., 1997). Moderate dietary habits with natural bioactive agents, antioxidants, methyl donor molecules and metal elements can help restore the normal function of the organism, although the immoderate consumption of nutritive components is contraindicated. Long term antioxidant and/or antioxidant-related treatments as well as metal element owerflow can modify redox-homeostasis because these alimentary components effect signal transduction routes and compensatory effects of altered tissues can be observed (Vanherweghem et al., 1993, Blazovics et al., 2007a,b, Blazovics et al., 2008). Epidemiological, experimental and clinical investigations have shown that food supplements are not effective in cancer therapy because of inappropriate usage in cases of people suffering from cancers with low vitamin and trace element levels. Significant changes of total scavenger capacity, metal element concentrations, bounded HCHO and
