Brief Summary

Background: Low physical activity and poor eating habits (incl. high fat and carbohydrates but low fiber intake) are the main reason of obesity epidemic in western societies. The most common clinical complication of this condition is non-alcoholic fatty liver disease (NAFLD), that can lead to liver cirrhosis and its complications. Recent studies show that gut dysbiosis may play a crucial role in the pathogenesis of NAFLD. On the other hand plant fiber shows beneficial properties in remodeling of the gut microbiome. Aim: The project aims to create low-calorie bars / snacks with an increased fiber content (12 g/bar), replacing the second breakfast and/or afternoon tea. The main scientific aim is to examine the influence of the extra supply of fiber on i. gut microbiota composition and metabolism and ii. liver function in patients with NAFLD. Methods: Randomized placebo-controlled double blind study. A group of patients diagnosed with NAFLD, divided into 2 groups: study (12% fiber bar) and placebo (maltodextrin bar). Two study phases: preliminary study (5 weeks, 20 patients) and main study (24 weeks, 120 patients). Both clinical and laboratory (stool and serum) aspects will be analyzed, incl. anthropometric measurements, nutrition tests (food frequency questionnaire), health-related quality of life, liver ultrasound and elastography, serum and stool biochemistry and microbiome analysis.

Study group

EXPERIMENTAL

30 patients with NAFLD which consumes rolls with a higher fiber content twice daily (ca. 300 kcal; no less than 12 g of fiber) for 8 weeks.30 patients with NAFLD which consumes rolls with a higher fiber content twice daily (12 g of fiber/per roll) for 8 weeks. Rolls should be eaten for 1st and 2nd breakfast. Before starting the study, patients will receive nutritional guidelines how compose a meal that the caloric content does not exceed 400 kcal per breakfast. At the beginning patients will be trained by licensed dietitians on the principles of diet in NAFLD. During 8 weeks of intervention, patients will have telephone access to consultations with a dietitian.

Dietary Supplement: plant fiber

Interventions

plant fiberDIETARY_SUPPLEMENT

The patients with NAFLD (study and control group) will receive low-processed rolls with an 12 g plant fiber content twice daily, which would be a convenient for easy replenishment of the amount of vegetable fiber (act as prebiotic) in the diet. The intervention will be preceded by a 21 day wash-out period during which subjects will be asked to avoid foods containing large amount of fiber.

Also known as: high fiber rolls
Study group
maltodextrin barDIETARY_SUPPLEMENT

The patients with NAFLD (placebo group) will receive maltodextrin bars twice daily, which would be a convenient and easy-to-eat snack replacing the second breakfast and afternoon tea. The bars must be eaten with 180 ml of water or unsweetened liquid. The intervention will be preceded by a 21 day wash-out period during which subjects will be asked to avoid foods containing large amount of fiber.
