Abstract: As one of the seven essential nutrients for the human body, protein plays a crucial role in maintaining human health. High protein intake and highly processed foods will inevitably increase the intake of oxidized protein. However, accumulating studies have indicated that oxidized protein intake has potential threats to body health, such as negative effects on intestinal health, oxidative stress and organ function. This review describes the relationship between dietary oxidized protein and oxidative stress in the body, outlines the pathway and mechanism of dietary protein oxidation, and discusses the association of dietary oxidized proteins with body health. We expect that this paper will theoretically guide further studies on the relationship between dietary protein and body health.

Key words: dietary; oxidized protein; body health
