Commonly diffused foods like milk, wheat, meat, and spinach may produce after enzymatic digestion a variable amount of opioid peptides. The aim of this review is to provide arising perspectives on opioid peptides, focusing on their production from milk, their potential benefits, drawbacks, and safety issues related to infants' feeding.en10.1080/87559129.2016.1225220info:eu-repo/semantics/closedAccessCaseincasomorphinexorphinsmilknutraceuticalsopioidReview3417086Q1WOS:000415968100004Q1
