Antioxidants are man made or natural molecules that prevent or delay cell damage. More specifically, they inhibit the oxidation of other cells. Oxidation occurs when oxygen molecules in the body interact with other molecules. The result is the production of free radicals, atoms or groups of atoms with an odd number of electrons. It looks a little something like this:

Once the free radicals are formed, they can start a chain reaction. It gets dangerous when they react with major cell components, like our DNA or cell membranes. If this happens, cells can be damaged or even die.

Antioxidants prevent the free radicals from developing a chain reaction. Woohoo!

Some scientific studies have shown that a diet rich in antioxidants prevent agains cancer. So, eat your fruits and veggies!
