Below is a snippet, click the link above if you want to read the rest.
"We do not catch a bacterial infection because we don't have enough antibiotics coursing through our blood stream. We do not get cancer because we do not have enough chemotherapy in our bodies. We do not get heart disease because we do not have enough heart medications in our medicine cabinets. And we do not get clinically depressed because we're not knocking back enough antidepressants each morning.
In your basic biology class we are taught that our blood is manufactured, that it begins, in the bone marrow. In Chinese medicine, we are taught that our blood begins on the end of our fork: we are what we eat.
Is there a nutritional connection to depression?"
Well it sparked my interest ;-)
