Lactose-poor milk in adult lactose intolerance.

The frequency of lactose intolerance was studied in patients with chronic gastrointestinal disease, mainly peptic ulcer to explore the possibilities of the use of lactose-poor milk. It was found that whole milk caused dyspeptic symptoms in 45% of patients with peptic ulcer; lactose-intolerance was present in 82% of the patients with milk intolerance; lactose poor powdered milk resulted in complete freedom from symptoms. Use of milk with reduced lactose contents is recommended in the diet of adult patients with lactase deficiency.
