How would you encourage someone with ulcers to get on a diet?

In the olden times: The diet was the only answer. Dairy and especially milk, liquid antacids and avoidance of spiced foods. We now know that ca++ stinulates gastrin, a hormone that stimulates acid prodcution. The modern attack is on the systems that produce gastric acid, the focus of treatment like ranitidine, famotidine, omeprazole. Avoid foods causing dyspepsia.
