What are antioxidants? How do they work and what is their role in disease prevention?
Free radicals, that are trying to achieve stability, steal electrons from cells within the body, creating a hole or cell damage. Missing one electron, free radicals form as the body breaks down oxygen atoms. This is unstoppable. In turn, cells steal electrons from other cells, creating damage via the domino effect. If enough damage occurs, it contributes toward a disease process. Free radicals oxidize or damage other cells through the body accelerating the aging process. Antioxidants can stop the damage either by stabilizing free radicals or repairing damage already done by free radicals. Vitamin C, Beta Carotene or Selenium can come in and repair the damage or stop the chain from continuing.
Antioxidants may have an effect in reducing LDL oxidation and possibly attenuating the risk of developing heart disease. The oxidation of polyunsaturated fatty acid residues in low-density lipoprotein cholesterol can increase its potential to induce arteriosclerosis and increase the risk of cardiovascular diseases. This is why many organizations advocate eating a minimum serving of 5 fruits and vegetables a day, because they have high antioxidant content.
