A systematic literature search was performed in three databases: Medline, Embase, and Web of Science. Systematic reviews published between January 2014 and February 2024 based on randomized controlled trials (RCTs), prospective cohort studies, case-control studies, and/or cross-sectional studies in adults, focusing on the consumption of bovine dairy products were evaluated for inclusion.

Overall, the evidence suggests that consuming dairy is not associated with an increased risk of non-communicable diseases or mortality. In fact, it may moderately reduce the risk of several health outcomes, including adverse cardiovascular outcomes and certain cancers such as bladder, breast, colorectal, liver, oral, and ovarian.

Three databases were searched to obtain randomized controlled trials involving four interventions for postoperative nutritional supportive therapy in abdominal surgical patients. We used The Cochrane Handbook tool (2.0) to assess the risk bias of included studies. The primary outcome was the occurrence of postoperative adverse events.
