Breastmilk is the golden standard infant feeding. Scientists try all over the world to mimic human milk as closely as possible. The addition of pre- and/or probiotics to infant feeding is a recent example of this principle. By adding prebiotics to infant feeding, the colonic flora of the infant becomes richer in bifidobacteria and lactobacilli. Although the addition of prebiotics seems to be safe up till now, it is not known whether doing so will improve the health of the infants.
