Antioxidants: Things To Know

What are antioxidants?
The cells in your body are exposed to oxygen every day. Oxygen is important for the health of the body, but exposure to oxygen also causes oxidation. During oxidation, chemicals in the body are transformed and form free radicals. Exposure to environmental factors, such as exposure to the sun, cigarette smoke, alcohol and pollution sources, also creates free radicals.
Over time, free radicals can cause a chain of reactions in the body, damaging important chemicals, DNA, and parts of cells

. Some cells can recover, but others are permanently damaged. Scientists believe that free radicals can contribute to aging as well as cancers, diabetes and heart disease.
Antioxidants are natural substances that can prevent or limit the damage caused by free radicals The body uses antioxidants to stabilize free radicals, preventing them from damaging other cells.
