Antioxidants - What are they and why are they important?
Before we get into the nitty-gritty of how this all works, let me clarify some of the pertinent lingo.
free radicals. (sometimes the bad guys) -- free radicals are oxygen containing molecules. Because they have an uneven number of electrons, they react easily with other molecules. Their reaction is called oxidation (like rust forming on an old bike or an apple turning brown after you bite into it). Oxidation can be beneficial or it can be harmful (leading to illness and diseases).
antioxidants (the good guys) -- an antioxidant is a molecule that can stabilize a free radical by donating an electron to it. This stabilization of the free radical helps to prevent it from causing harm, illnesses, or diseases.
the goal -- to keep enough antioxidants in your system so free radicals don't cause damage -- illness or disease.
Where do we get free radicals?
Our bodies produce some free radicals, but some come from pollution, ozone, pesticides, cleaners, radiation, effects of the sun, and a diet high in sugar, fat, and alcohol. By avoiding as many of these causes as possible, we increase our chances of keeping a balance between free radicals and antioxidants. Another way to keep free radicals working for us is to eat more food rich in antioxidants.
