Milk is commonly recommended as therapy for patients with peptic ulcer. The purpose of this study was to examine the effect of various forms of milk and 0.15 M NaCl (control) on gastric-acid secretion in five patients with duodenal ulcer during a period of remission and in five normal subjects. A significant (P < 0.05) increase in acid secretion in both groups was produced by 240 ml of whole, low-fat, and nonfat milk. The acid secretory responses to milk were equivalent to those produced by a 300-ml 10%-peptone meal and were approximately 20% to 35% of maximal betazole- or pentagastrin-stimulated acid output. Gastric-acid secretion did not increase after 0.15 M NaCl. Low-calcium milk produced a significant (P < 0.05) increase in acid secretion in the patients with duodenal ulcer but not in the normal subjects. Because milk contains both protein and calcium, and each are stimulants of gastric-acid secretion, there is reason to question its frequent ingestion by patients with peptic ulcer.
