High dietary intake of dietary polyphenols is associated with a decreased risk of chronic diseases, especially in inflammation. However, mechanisms responsible for their anti-inflammatory effect in vivo are still not fully understood. Many animal studies showed the beneficial effects of polyphenols on inflammation, but in clinical trials the results were variable, some of them are negative. Despite the initial successes demonstrated in animal and early clinical trials regarding the safety and efficacy of polyphenols, a number of challenges, problems, and unanswered questions remain. This review briefly summarizes recent research investigating the effects of dietary polyphenols on inflammation and metabolic disorders in vivo. Biological activities and general anti-inflammatory mechanisms, certain receptor targets, and recent clinical evidences of polyphenols are fully discussed. Safety issues, potential uses of nanodelivery system and polyphenol polymers, and directions for future research are also briefly discussed.
