Administration of higher doses of amaranth and quinoa seeds provided a protective mechanism, since the concentration of malondialdehyde in plasma decreased significantly, as compared to the control group. Amaranth\-enriched fodder, especially in a higher dose, caused a significant increase in catalase and glutathione peroxidase activities in heart tissue of the investigated animals, as compared to the control group. Supplementation with fructose\-enriched fodder did not lead to a decrease in glutathione peroxidase activity in this group. It can be concluded that the level of antioxidants present in heart tissue was raised through supplementation with amaranth seeds. These results confirm earlier findings on the advantageous effect of amaranth seeds on the cardiovascular system. Interesting results could be observed in rats supplemented with quinoa. In comparison with groups fed on different fodder, this group had significantly lower activity of enzymes in heart tissue. However, in response to fructose induced stress, a significant increase in glutathione peroxidase was observed, which is indicative of the protective response of cardiomyocytes against free radicals. Therefore, diet therapy can be successfully employed to restore the right concentration of antioxidants, both as a preventive measure, and on a short\-term basis to protect"]
