What kind of damage can be caused by oxidation?
Overproduction of free radicals can cause oxidative damage to biomolecules, (lipids, proteins, DNA), eventually leading to many chronic diseases such as atherosclerosis, cancer, diabetics, rheumatoid arthritis, post-ischemic perfusion injury, myocardial infarction, cardiovascular diseases, chronic inflammation, stroke
What vitamin protects cells from free radicals?
Although there are several enzyme systems within the body that disarm free radicals, the principal antioxidants are vitamin E, beta-carotene, vitamin C, and selenium. When these antioxidants neutralize free radicals by donating an electron particle they are left with a small problem.
Why is free radicals bad?
Free radicals are unstable atoms that can damage cells, causing illness and aging. Free radicals are linked to aging and a host of diseases, but little is known about their role in human health, or how to prevent them from making people sick.
Do antioxidants kill bacteria?
Antioxidants are chemicals that may help fight damage due to disease and aging. These powerful compounds work by blocking oxidation. That’s a type of natural chemical reaction (often involving oxygen) that can harm cells. Among those good tasks: killing off old cells and germs.

Free radicals and other ROS are derived either from normal essential metabolic processes in the human body or from external sources such as exposure to X-rays, ozone, cigarette smoking, air pollutants, and industrial chemicals.
How do free radicals cause cancer?
The damage to cells caused by free radicals, especially the damage to DNA, may play a role in the development of cancer and other health conditions (1, 2). Abnormally high concentrations of free radicals in the body can be caused by exposure to ionizing radiation and other environmental toxins.
