The aim of the study is to evaluate the beneficial effects of the administration of enteral nutrition product with milk proteins, monounsaturated fatty acids and low dextrose equivalent maltodextrin and enriched in eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and medium chain triglycerides (MCT) in patients with mild acute pancreatitis. All this against other specific product.

The main objectives of this project are:

• Comparing the tolerance of both preparations.
• Comparing the evolution of nutritional status in both groups.
• Comparing the evolution of inflammatory parameters in both groups

Oral administration of an oligomeric formula with milk proteins, mainly whey protein partially hydrolysate, monounsaturated fatty acids (AGM) and low dextrose equivalent maltodextrin and enriched in polyunsaturated fatty acids (PUFA) of omega-3 series, EPA and DHA, and MCT designed for nutritional support of patients with compromised intestinal function, to maintain or improve nutritional status and reduce the inflammatory response in undernourished patients with mild acute pancreatitis, compared with oligomeric enteral nutrition product, low in fat and rich in glutamine.
