Abstract: Long-term intake of high-fat diet can easily induce oxidative stress and inflammation, increasing the risk of
chronic metabolic disorders such as obesity and type 2 diabetes. Anthocyanins, a group of natural soluble pigments isolated
from plants, with a variety of biological activities such as anti-oxidation, anti-obesity and anti-inflammation, have become
the focus of research for their potential in the prevention and treatment of chronic metabolic diseases. In this article, the
recent progress in understanding the effect and mechanism of anthocyanin intervention on obesity induced by high-fat diet is
summarized, with the aim to provide a theoretical reference for the application of dietary anthocyanins to prevent and treat
chronic metabolic diseases, as well as for the development and utilization of natural active substances.

Key words: anthocyanins, oxidative stress, inflammation, obesity
