Regarding this topic, I thought I'd pass on what I found at the other website posted by MantisStyle. He says this is from the same book by Dr. Wilson:
Regarding the yeast thing, apparently copper is used by the body to keep yeast under control. But when the adrenals are weak, the copper is not properly bound, so it accumulates and cannot be used by the body. So maybe if someone with yeast problems can get their adrenals under control with active b12, zinc (antagonistic to copper), vitamin e, (i would guess selenium), and other vits/ minerals, maybe the yeast would be properly controlled again.
Here is the link:

and a quote from it:
Copper is the bodys natural anti-candida agent. Farmers often spray copper sulfate on fruits and vegetables to kill yeast and molds. Water departments may add copper compounds to drinking water for the same reason. Copper may be added to swimming pools and hot tubs to control yeast. Copper favors aerobic metabolism which disables yeast.
Everyone with candida has a copper imbalance. Most often, copper is present but not available to the body. This is due to deficiency of ceruloplasmin, a copper binding protein. Adrenal hormones are required to produce ceruloplasmin. Underactive, exhausted adrenal glands or sluggish liver activity cause a decrease in ceruloplasmin production. As a result, copper is not properly bound and is less available to the body. Until the copper-adrenal-liver condition is corrected, candida is difficult to control.
So, basically, copper builds in the tissues, but it cannot be utilized I believe unless the body is producing enough ceruloplasmin which is the job of the adrenals...
