Abstract

Phytochemicals, the diverse bioactive compounds found in plants, have garnered significant attention due to their potential health benefits. These compounds, including polyphenols, flavonoids, carotenoids, and glucosinolates, exhibit a wide range of biological activities that contribute to disease prevention and health promotion. This review explores the types, sources, mechanisms of action, and health benefits of phytochemicals. We also discuss their role in the prevention and management of chronic diseases such as cardiovascular diseases, cancer, diabetes, and neurodegenerative disorders. The emerging trends and future perspectives in phytochemical research are also highlighted.
