Oxidative Stress
We obtain energy by burning fuel with oxygen--that is, by
combining digested food with oxygen from the air we breathe. This
is a controlled metabolic process that, unfortunately, also
generates dangerous byproducts. These include free
radicals--electronically unstable atoms or molecules capable of
stripping electrons from any other molecules they meet in an effort
to achieve stability. In their wake they create even more unstable
molecules that attack their neighbors in domino-like...
