Let starts with "oxidants" first. What is the meaning of oxidants? Looking into our body's daily functions, such as breathing and metabolising food and the exposure to such environmental hazards as pollution, produce stray molecules known as free radicals. Free radicals can oxidise, or interact with oxygen molecules, and damage cells.
Antioxidants can prevent these free radicals do harm to our body. Different types of antioxidants, such as from the anthocyanins and caretenoids to isoflavones and lutein, playing different roles in protecting against certain kind of cell damage.
For example, Vitamin C or Ascorbic acid, and lycopene, helps in reduce DNA damage. Flavonoids which found in fruits and vegetables are thought to reduce the production of free radicals. While phenolics which found in teas, beans and cabbage, may slow heart disease.
Antioxidants are important in nutrition world. They are valueable for their health-promoting and disease-busting qualities.
