Extract: A calcium absorption investigation was carried out with the purpose of determining whether lactose-hydrolyzed milk facilitates calcium absorption in subjects with lactose malabsorption. Nine children participated in the study, which was divided into 2 investigation periods separated by at least 1 week. During the first period the children were given a lactose-free diet, whereas during the second period their diet contained lactose-hydrolyzed milk. The amount of calcium, number of calories, and rotation of specifically defined meals in the diet during the 2 periods were identical, and the children functioned as their own controls. Calcium absorption was found to be significantly higher with the diet containing hydrolyzed milk than with the lactose-free diet supplemented with extra calcium. During the study a double-blind lactose intolerance test was performed. The children had significantly fewer clinical symptoms and signs, such as abdominal pain, borborygmus, meteorism, and defecations, within 24 hours after drinking 0.5 L of lactose-hydrolyzed milk as compared with drinking ordinary milk (25 g of lactose). None of the children experienced any unpleasant side effects when consuming the lactose-hydrolyzed milk (approximately 94% degree of hydrolysis) during the study period. All the children liked the hydrolyzed milk because it had a pleasant, sweet flavor as a result of the increased content of glucose. (author)
