What are phytochemicals?

Phytochemicals are bioactive compounds that are naturally found in plants and may offer various health benefits. These compounds contribute to the color, flavor, and disease resistance of plants, and research suggests that they can also play a role in promoting human health. For example, certain phytochemicals are associated with antioxidant properties, immune support, and the reduction of inflammation. They can be found in a wide range of foods, particularly fruits, vegetables, whole grains, nuts, and seeds.

In contrast, essential nutrients for human survival are classified as vitamins, minerals, proteins, fats, and carbohydrates, which are required in specific amounts for proper body function. Synthetic compounds used in dietary supplements, while sometimes containing plant-derived extracts, are not classified as phytochemicals. Minerals necessary for enzymatic reactions are inorganic substances that play crucial roles in various physiological processes and are different from the naturally occurring compounds found in plants that fit the definition of phytochemicals.
