<p>The pancreas plays a&#xa0;central role in metabolism, which is why pancreatitis can cause significant metabolic disorders. However, the different aspects of acute and chronic pancreatitis must be taken into account in nutritional therapy. In patients with acute pancreatitis who are able to tolerate oral food intake, early food intake is crucial to avoid complications. Even in severe acute pancreatitis, oral or enteral nutrition should be the preferred option over parenteral nutrition. Enzyme substitution is only indicated in (severe) forms of the disease with proven exocrine insufficiency. Therapeutic approaches with dietary supplements to support recovery are not recommended based on current scientific evidence. Chronic pancreatitis requires personalized nutritional therapy, as many patients suffer from malnutrition. An essential component of treatment is adequate substitution of pancreatic enzymes in the case of existing exocrine insufficiency. It is also very important to recognize malnutrition and malabsorption disorders at an early stage and specifically counteract them. In addition to alcohol restriction, the early identification and treatment of specific nutrient deficiencies and their clinical consequences (e.g., osteoporosis) play a&#xa0;key role.</p>
