Fish –based diet- correlations between metabolism of carbohydrates, lipidis and proteins. Study case population of the Sulina Town, Danube Delta

According to literature data, the normal values of biochemical parameters in blood vary by sex, age, geographical region, and type of diet. The aim of this study was to analyze the benefits of a fish-based diet among the population of Sulina, in the Danube Delta (3,663 individuals), by performing a comparative hepatic evaluation, lipid profile, serum glucose levels and total protein profile of these patients. Fish is an important source of protein with high biological value, containing all essential aminoacids and low lipid levels. The novelty of the research is represented by the analyzed geographical area. The Danube Delta had no medical analysis laboratory until 2010, when the RoutineMed Sulina laboratory was opened. Patients had a set of biochemical tests in the RoutineMed Sulina laboratory and declared they eat fish or fish-based products at least once a week. Tests were performed on 200 patients for the evaluation of the liver of these patients: Aspartate Amino Transferase, alanine amino transferase, de Ritis ratio, High Density Lipoprotein, Low Density Lipoprotein, total lipids, total cholesterol, triglycerides and 200 tests for the evaluation of the serum glucose levels and total protein. Both women and men were involved in the research and patients were grouped into age ranges: 20-40 years, 40-60 years, > 60 years. The values obtained were statistically analyzed using the SPSS v. 20 software and then compared to the ranges considered normal for these parameters. The results obtained showed that patients with a fish-based diet seem to be healthier than those with a diet in which fish meat is scarce, as their blood biochemical parameters values are closer to normal, which leads to the conclusion that including fish and fish products in people's regular diet is beneficial in preventing lipid, protein and carbohydrate metabolism disorders and preserving the overall health of the body.
