Health effects of polyphenols and flavonoids

Plants are the most important source of compounds that are very beneficial for the human body, including antioxidants. Therefore, the study of compounds in plants and their use in human nutrition is of great importance in our time. In this regard, this research work was aimed at studying the health effects of flavonoid and polyphenolic compounds, which are relevant in modern times. The article examines the works of many local and foreign researchers and summarizes the results obtained. It has been determined that flavonoids of natural origin have been the focus of increasing attention of researchers for many years and are widely used. Polyphenols have been the subject of many scientific studies due to their positive effects on health. These studies investigate how polyphenols act in the body and by what mechanisms they improve health. This is mainly due to their valuable medicinal value, as they are a source for capillary-strengthening, anti-inflammatory, choleretic, anti-sclerotic, anti-cancer, etc. preparations. Recently, attention has also been paid to the antioxidant properties of flavonoids. The role of polyphenols in preventing cardiovascular disease has been highlighted in many studies in recent years. Polyphenols lower blood pressure by dilating blood vessels, inhibit the oxidation of LDL (bad cholesterol), and increase HDL (good cholesterol) levels.
