Functional Roll for Non-alcoholic Fatty Liver Disease

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.

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.
