In recent years, major developments in the field of inflammatory pathophysiology have clearly shown that arthritis, diabetes, intestinal bowel diseases, and obesity, which affect many people around the world, are essentially inflammatory in nature. Different anti-inflammatory drugs have been used to treat these conditions. Some people are able to take these drugs without difficulty, yet others experience negative side effects. Hence, the search for new, natural anti-inflammatory alternatives has rapidly increased in recent years. Evidence has shown that food protein-derived peptides may be one alternative for treating inflammatory diseases. Peptides are encrypted in food proteins, can be released under hydrolysis conditions, and do not cause adverse effects. Despite limited information on the mechanism of action of peptides, in vitro and animal model studies have demonstrated their potential anti-inflammatory activity. Several in vitro studies have demonstrated that peptides can inhibit different pathways of inflammation processes such as that of the nuclear factor kappalight- chain of activated B cells (NF-κB). They can also induce the production of nitric oxide synthase (iNOs) and c-Jun N-terminal kinases (JNK) as well as influence PepT1 and CaRS, the transporters of peptides to the gastrointestinal tract that are responsible for the absorption of dietary peptides in the intestine. However, contradictory evidence has been reported in clinical assays. Hence, in this review, we present the latest research on the anti-inflammatory activity of food protein-derived peptides and provide future perspectives on the use of peptides as potential natural sources of therapeutic treatments.
