“…of Nutrition at 8:30 h. They drank 200 mL of mineral water with 20 g of lactose. As previously described [7], breath samples were obtained by end-expiratory sampling into 60 mL plastic syringes through a modified Haldane-Priestley tube. Two basal breath samples were obtained at a 10 min.…”

“…One way to continue consuming dairy products for intolerant people is, for example, to consume yogurt with live bacteria. Indeed, multiple clinical studies have shown that the lactase of yogurt bacteria continues hydrolyzing lactose in the human intestine, reducing the development of digestive symptoms [7]. Based on these studies, the European Food Safety Authority (EFSA) authorized a health claim stating that "the consumption of yogurt with live bacteria improves lactose tolerance in hypolactasic subjects" [8].…”

Although Bifidobacterium bifidum expresses lactase activity, no clinical trials have determined its impact on lactose-intolerant subjects. This study evaluated whether acute and chronic ingestion of ice creams containing B. bifidum 900791 at high (107 CFU/g) or low (105 CFU/g) concentrations improved lactose tolerance in hypolactasic subjects. Fifty subjects were selected based on a positive lactose (20 g) hydrogen breath test (HBT0) and the presence of digestive symptoms. The recruited subjects were required to perform breath tests after the acute ingestion of: (1) ice cream containing 20 g of lactose without a probiotic (HBT1); (2) the same ice cream, accompanied by a lactase tablet (HBT2); (3) the same ice cream containing the low or high dose of probiotic (HBT3-LD and HBT3-HD); and (4) after the chronic consumption of the ice cream without (placebo) or with the low concentration of probiotic for 1 month (HBT4). Significant decreases in H2 excretion during HBT2 and HBT3-HD as well as digestive symptoms during HBT2, HBT3-HD and HBT3-LD were observed compared to HBT0 and HBT1, while the orocecal transit time increased. Chronic consumption of the probiotic ice cream did not enhance lactose tolerance compared to the placebo. These results suggest that the acute ingestion of ice cream containing high or low concentrations of B. bifidum 900791 improves lactose tolerance in hypolactasic subjects.
