Oxidation

When fruit such as apples or pears turn brown, it is called oxidation.  Oxidation also occurs when a cut on your skin is inflamed.  This is due to free radicals reacting with the electrons of objects that they come into contact with.  Oxidation is, in short, when living objects start to decay.  However it is nothing to worry about as it is a natural part of life!  Oxidation can be prevented by eating antioxidants which can be found in many fruits, vegetables, whole grains, and nuts.
