Role of dietary fibers in the nutritional management of hyperuricemia

Foods rich in adenine and hypoxanthine may contribute to the increase of uricemia. Hyperuricemia is associated with other pathological conditions pertaining to metabolic syndrome. Objective: the assessement of the impact of fiber rich diet on uricemia in patients with metabolic syndrome. Methods: the study involved 46 male patients with metabolic syndrome who claimed to have reduced mobility in fingers, hypertension, obesity, hyperglycemia and hyperuricemia. A validated questionnaire about dietary habits was applied at the beginning of the study and after 6 weeks of fiber-rich diet by eliminating from patients diet preparations of animal food and increased intake of vegetable foods. Blood presure, body mass index, blood glucose and uric acids were measured at the beginning of the study and after 6 weeks of fiber rich diet by daily consumption of 2 servings of added grains - 60g totally and vegetables 200g, fruits 300g respectively. Results: The study shows that at baseline all patients had an inadequate dietary intake of dietary fiber, 28.5 ± 2.2 g/day instead of 38 g per day.The increase in fiber intake of 10 ± 5 g/day was associated with a decrease of serum uric acid by 69.87% from 8.3  0.6 mg/dL to 5.8  0.5 mg/dL, p = 0.008, non-significant decrease of BMI (from 26.8  4.5 to 26.4  4.6 kg/m2, p<0.01), significant decrease of glycemia (from 130  0.8 to 105  4.2mg/dL, p <0.001) and significant decrease in blood pressure (from 150  10.6 to 130  8.4 mmHg, p <0.001). Conclusion: The fiber rich diet decreased blood uric acid, blood glucose levels an arterial pressure in patients with metabolic syndrome.

Knowledge and attitudes towards dietary fibers - romania vs other european countries

Aim: The aim of our study was to evaluate the Romanian’s knowledge and attitudes regarding dietary fibers compared with other European countries. Materials and methods: We made a cross-sectional survey (part of multinational project from CI&DETS Research Centre, Instituto Politecnico Viseu, Portugal, with reference PROJ/CI&DETS/2014/0001) based on a questionnaire applied in 2015, over 670 Romanian consumers, focused on the attitudes and knowledge towards ingestion of foods rich in fibers. We used the software SPSS for statistics. Results: Our results showed that the knowledge about dietary fibers and also the ingestion of food products rich in fibers were low. The female participants ate more whole grains and fruits than males and pay more attention to food labelling, the Romanian people prefer to stay and eat home than at restaurants especially in rural areas, and the knowledge about fiber’s benefits was significantly related to high education and urban location. Comparing to other European countries, Romania had the highest level of knowledge about dietary fibers definition followed by Portugal, Turkey and Hungary, but the lowest regarding the fibers importance for health after Macedonia, Turkey and Latvia. Conclusion: We sustain the needs for more efficient community interventions and proper information about the importance of dietary fibers for our health and also for the dissemination of the nutritional standards among Romanian population.

Romanian Knowledge and Attitudes regarding Dietary Fibers

Presently, the scientists recognize the health benefits of food fibers in the menu and also plant food sources are at high interest both for general population and food companies. The food companies are responsible for a clear nutrition labelling that will assist consumers to make informed and healthy choices and health providers has to inform the population about the benefits of fibers.The aim of our study was to evaluate the Romanian knowledge and attitudes regarding dietary fibers from food products. We made a qualitative survey based on a questionnaire applied in 2015, over a period of 6 months, over 670 Romanian consumers. It was focused on testing the attitudes and knowledge towards ingestion of foods rich in fibers. For all data analysis we used the software SPSS, from IBM Inc. Our results showed that the knowledge about dietary fibers and also the ingestion of food products rich in fibers were low, and most of the subjects didn’t have any interest to read the nutritional information from food labels. The female participants ate more whole grains and fruits than males and pay more attention to food labelling. Romanian people prefer to stay and eat home than at restaurants especially in rural areas, and the knowledge about fibers benefits was significantly related to education and urban location. We underline the needs for more efficient community interventions and proper information about the importance of dietary fibers for our health and also to improve and disseminate nutritional standards and diet recommendation among population.
