Composition of soluble indigestible fibers and of microalgae, used in the well-being field

Abstract

The subject matter of the present invention is the use of soluble indigestible fibre for inducing lysis of the cell walls of eukaryotic microalgae in the lumen of the intestine of an omnivorous or carnivorous animal comprising an intestinal flora and also for synergistically increasing the effect of the indigestible fibre in the induction of the growth of the intestinal flora of an omnivorous or carnivorous animal. The subject matter of the invention is also the composition intended for this use and for a method of improving the health or of food supplementation.
