Bioactive compounds are natural substances found in various foods, particularly in fruits, vegetables, grains, and herbs. These compounds can have beneficial effects on health, often acting as antioxidants, anti-inflammatory agents, or supporting the immune system. Common examples include flavonoids, polyphenols, and carotenoids, which contribute to the color and flavor of plants. Research suggests that consuming a diet rich in bioactive compounds may help reduce the risk of chronic diseases such as heart disease, diabetes, and certain types of cancer. These compounds work by interacting with biological systems, promoting overall well-being and enhancing the body's ability to fight illness.
