Free radicals are also known as reactive oxygen species (ROS).įactors that increase the production of free radicals in the body can be internal, such as inflammation, or external, for example, pollution, UV exposure, and cigarette smoke. If the body cannot process and remove free radicals efficiently, oxidative stress can result. Antioxidants that come from outside the body are called exogenous.įree radicals are waste substances produced by cells as the body processes food and reacts to the environment. The body also produces some antioxidants, known as endogenous antioxidants. Plant-based antioxidants are a kind of phytonutrient, or plant-based nutrient. Certain plant-based foods are thought to be rich in antioxidants. The sources of antioxidants can be natural or artificial. They are sometimes called “free-radical scavengers.” Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, unstable molecules that the body produces as a reaction to environmental and other pressures.
