What this Trial Is About
The role of the intestinal microbiota on health is now well recognised, and diet is one of the factors influencing the maintenance of a healthy intestinal microbiota. More specifically, the consumption of fruit, vegetables and cereals is associated with good health and, in particular, with an increase in the relative abundance of bacterial groups described as beneficial. To date, a large number of bacterial species in the intestinal microbiota have yet to be isolated and cultivated, which limits the characterisation of their potential health benefits. In order to isolate and cultivate these intestinal bacteria, it is particularly relevant to recruit individuals with a high-fibre diet.
