What are phytochemicals?

Phytochemicals are biologically active substances found in plants that contribute to both the color and flavor of the plants and have potential health benefits for humans. These compounds are not classified as essential nutrients but have been shown to have various effects on health, including antioxidant properties, anti-inflammatory effects, and potential roles in disease prevention. They are abundant in fruits, vegetables, grains, legumes, nuts, and seeds. Certain phytochemicals are thought to contribute to the protective health benefits associated with a diet rich in plant-based foods.

Understanding phytochemicals is important because they play a role in promoting health and reducing the risk of chronic diseases. Recognizing that they come from plant sources distinguishes them from vitamins and minerals, which are essential nutrients, or artificial additives that may be found in processed foods, which have no natural health benefits related to whole foods.
