Influence of dietary caloric structure on the free amino acid content in the blood of hyperstress-reactive rats

Year: 2026

Type: article

Abstract: The study investigates the influence of dietary caloric structure on free amino acid metabolism in hyperstressreactive rats, considered analogues of the asthenic constitutional type. Four experimental groups were fed diets differing in protein, lipid, and carbohydrate proportions. Protein metabolism was assessed by determining free amino acid concentrations in blood serum and erythrocytes, as well as by analyzing major functional amino acid groups. The results demonstrated that the diet containing 12% protein, 27% lipids, and 61% carbohydrates induced a significant increase in total free amino acids, including immunoactive, glucogenic, ketogenic, and proteinogenic amino acids. This caloric structure ensured the most favorable metabolic response under conditions of increased stress. The findings support the concept of constitutionally differentiated nutrition and highlight the importance of optimizing dietary protein content to maintain metabolic balance in stress-reactive organisms.
