Chronic diseases are major contributors to global morbidity and mortality. More than 70% of deaths worldwide are caused by chronic diseases, including cardiovascular diseases (CVDs), obesity, type 2 diabetes, and cancer. These diseases are characterised by chronic low-grade inflammation and metabolic dysregulation. Incorporating functional foods into daily diet has been suggested as a complementary strategy to promote health and lower the risk of non-communicable diseases. Functional foods, known as foods that confer health benefits beyond basic nutrition, have been reported to exhibit preventive and therapeutic benefits such as anti-inflammatory properties for human health. Therefore, the aim of this state-of-the-art review will synthesise the findings from recent and high-quality studies that investigated the modulatory role of some commonly reported bioactive active compounds, such as polyphenols, omega-3 fatty acids, probiotics, and prebiotics, in inflammation and metabolic pathways.
