High cholesterol in itself isn't necessarily bad. I'd study the role of copper, and the copper-depleting effects of supplementation with Iodine and zinc. I eat calf liver twice a month for its copper and other trace elements. When copper is low or depressed/masked, a person can manifest many different negative symptoms in many different bodily compartments.
I've read where D-mannose is a highly effective material for erradicating many UTI's.
