The rationale for focusing on food as a vehicle for the transmission of probiotics is that it has the potential to benefit children more than using probiotics in a more medicinal manner, such as pills or capsules. By providing an intervention in the form of a yogurt drink, parents are given a more convenient and simple alternative to traditional probiotic supplements. As yogurt is known to be a nutrient dense food, a yogurt drink is likely to be more appealing to both children and their parents for long-term consumption than pharmaceutical-like preparations. Although compliance with most medicinal regimens is around 50%, by offering a more attractive formulation of high dose probiotics and collaborating with participants we believe compliance will exceed normal levels. Ultimately, by capitalizing on the widely accepted healthy image of yogurt and offering a simple, convenient source of probiotics, we believe this product has the potential to positively impact the health of children around the world.
