Modulation of the human gut microbiota is emerging as a plausible approach to promoting health and preventing and treating disease. Changes in dietary macronutrients, mainly in carbohydrates, exert specific effects on the human gut microbiota. Specifically, there is evidence that supports that dietary fiber may influence the abundance, diversity, and metabolism of the human gut microbiota. This work contributes to the understanding of the impact of intact cereal fiber consumption on the gut microbiota of healthy adults. The strongest evidence points to the role of wheat bran and wholegrain wheat fiber promoting gut microbiota diversity, since wheat fiber demonstrated the most consistent prebiotic effects, with demonstrable effects, with an increase in wheat fiber as low as 6 g/day.
