What are phytochemicals and where can they be found?

Phytochemicals are naturally occurring bioactive compounds found in plants that can confer various health benefits. They contribute to the color, flavor, and disease resistance of the plants themselves, and many of these compounds have been studied for their potential protective effects against chronic diseases in humans, such as heart disease and cancer.

Common sources of phytochemicals include fruits, vegetables, whole grains, legumes, nuts, and seeds. By consuming a diet rich in these foods, individuals can benefit from the diverse range of phytochemicals, such as flavonoids, carotenoids, and polyphenols, which have been linked to improved health outcomes. Thus, the essence of phytochemicals is closely tied to plant-based nutrition, making their classification as bioactive compounds from plants essential for understanding their role in a healthful diet.
