Antioxidants are molecules that help protect the body from damage caused by harmful molecules called free radicals. They can be found in a variety of foods, particularly fruits and vegetables, and are important for overall health and well-being. Secondary plant compounds are natural chemicals produced by plants that are not directly involved in the plant's growth, development, or reproduction. Instead, they often serve as defense mechanisms against predators, pathogens, and environmental stressors. Many secondary plant compounds also have potential health benefits for humans, such as antioxidant, anti-inflammatory, and anti-cancer properties. Examples of secondary plant compounds include flavonoids, polyphenols, and carotenoids. **
