Nutrients. 2022 Apr 20;14(9):1712. doi: 10.3390/nu14091712.


Phytonutrients comprise many different chemicals, including carotenoids, indoles, glucosinolates, organosulfur compounds, phytosterols, polyphenols, and saponins. This review focuses on the human healthcare benefits of seven phytochemical families and highlights the significant potential contribution of phytonutrients in the prevention and management of pathologies and symptoms in the field of family health. The structure and function of these phytochemical families and their dietary sources are presented, along with an overview of their potential activities across different health and therapeutic targets. This evaluation has enabled complementary effects of the different families of phytonutrients in the same area of health to be recognized.

Keywords: anthocyanins; caffeine; carotenoids; flavonoids; healthcare; organosulfur compounds; phenolic acids; phytonutrients; tannins.
