Digestive Tolerance of Slightly Hydrolyzed Starter Infant Formula With Probiotics

Tolerance of a Slightly Hydrolyzed Starter Formula Containing Probiotics

To demonstrate that infants have improved gut comfort when fed a slightly hydrolyzed starter formula containing probiotics compared to infants fed a control hydrolyzed and referenced non-hydrolyzed formula.

Infants often experience undesirable gastrointestinal effects, such as constipation, flatulence. These symptoms are often perceived by the parents as being related to the diet (formula) the baby is consuming. In another hand, infantile colic or fussing/crying is one of the most commonly encountered problems within the first three months of life. The etiology of the disorder remains unknown however, three main theories have been proposed to explain its origin: (i) psychological: due to inadequate mother-infant interaction (ii) gastrointestinal: such as hypertonicity and immaturity of the GI tract and Dietary factors that may influence the stool pattern in formula fed infants are (iii) allergic: due to a reaction against cow's milk protein or other food constituents. e.g. the protein source, the iron content, hydrolyzation of the protein, or the fat source.

It has been reported that infants receiving a casein predominant formula had less unformed stools than those receiving a whey predominant formula. Hydrolysation of protein resulted in reduced gastro-intestinal transit time and some studies using extensively hydrolyzed protein formula have shown more liquid stools.

A reduction of crying hours was also described in infant receiving an hydrolyzed formula. Some probiotics were reported with potential benefit on the gut comfort.
