Research suggests that free radicals have a significant influence on aging, that free radical damage can be controlled with adequate antioxidant defense, and that optimal intake of antioxidant nutrient may contribute to enhanced quality of life.

2022年7月19日 · Free radicals are unstable oxygen molecules. Left unchecked, they can cause premature aging and chronic disease. Fight free radicals with antioxidants.

2019年1月31日 · Antioxidants neutralize free radicals by giving up some of their own electrons. In making this sacrifice, they act as a natural "off" switch for the free radicals. This helps break a chain reaction that can affect other molecules in the cell and other cells in the body.

Free radicals and oxidants play a dual role as both toxic and beneficial compounds, since they can be either harmful or helpful to the body. They are produced either from normal cell metabolisms in situ or from external sources (pollution, cigarette smoke, radiation, medication).

2023年7月12日 · Antioxidants are molecules that can help your body fight off harmful free radicals, which have been linked to health conditions like diabetes and cancer. They’re found in many plant-based foods.

Free radicals and other reactive oxygen species (ROS) are constantly formed in the human body. Free-radical mechanisms have been implicated in the pathology of several human diseases, including cancer, atherosclerosis, malaria, and rheumatoid …

Free radicals, unstable molecules with unpaired electrons, are an unavoidable byproduct of cellular metabolism. Free radicals can steal electrons from lipids, proteins, RNA, and DNA, causing them damage. The body has defenses against free radicals—free radical detoxifying enzymes and antioxidants.
