What are phytochemicals?

Phytochemicals are bioactive compounds found in plants that may promote health. These naturally occurring chemicals are integral to plant structure and contribute to various health benefits when consumed by humans. They are known for their potential to reduce the risk of chronic diseases, such as heart disease and cancer, due to their antioxidant, anti-inflammatory, and immune-boosting properties.

In the context of the options presented, the other choices do not accurately describe phytochemicals. Synthetic additives used in food processing refer to man-made substances that may alter food's flavor, color, or shelf-life, which differs significantly from the natural origins of phytochemicals. Vitamins manufactured in laboratories also do not represent phytochemicals, as they are typically isolated nutrients rather than whole food compounds. Lastly, while minerals are crucial for various bodily functions, including bone health, they are inorganic elements and do not fall under the category of phytochemicals, which are specifically plant-based compounds. Hence, the definition of phytochemicals focuses on their origin, functions, and health benefits, making the first choice the most accurate.
