Abstract

This review will explore the observational and mechanistic evidence supporting the hypothesis that fermented milk consumption has beneficial effects on metabolism. Live cultures in fermented dairy are thought to contribute to gut microbial balance, which is likely an instrumental mechanism that protects the host against gut dysbiosis and systemic inflammation associated with cardiometabolic diseases. Lactic acid bacteria (LAB) release bioactive metabolites, such as exopolysaccharides and peptides, that have the potential to exert a wide range of metabolic and regulatory functions. In particular, peptides derived from fermented dairy products are likely to exert greater cardiometabolic and anti-inflammatory effects than nonfermented dairy. It is hypothesized that LAB-derived bioactive peptides have the potential to protect the host against cardiometabolic diseases through antimicrobial actions and to effect changes in gene expression of glucose regulatory and anti-inflammatory signaling pathways. The peptides released through fermentation may explain some of the health effects of fermented dairy products on cardiometabolic disease risk observed in epidemiological studies, particularly type 2 diabetes; however, mechanisms have yet to be explored in detail.
