Individuals who have pancreas issues should avoid uncooked vegetables, berries, prune juice, other high-fiber foods and alcoholic beverages, according to Everyday Health. Chronic pancreatitis patients should also avoid all high-fat foods, which often produce loose, greasy stools that carry a bad odor. Avoiding smoking also eases symptoms.
Patients with pancreas problems should avoid eating large meals and instead eat smaller meals more frequently to reduce pain during digestion, notes Everyday Health. Children and adults with cystic fibrosis who develop exocrine pancreatic insufficiency are an exception to the prohibition against a high-fat diet. To prevent stunted growth and weight loss in such children, and for general good health in adult patients, doctors often recommend high-fat, high-calorie regimens.
