T NATION | Liver Let Die:
"...cranberry juice cleanses the lymphatic system, which can help eliminate stubborn fat. Specifically, it helps provide nutritional support through phytonutrients (anthocyanins, catechins, luteins, and quercetin) for the liver's cytochrome P450 Phase 1 and 2 detoxification pathways"
"How does it work? The lymphatic system is responsible for carrying toxins away from the cells and body tissues. The phytonutrients in cranberry juice help to keep your liver's detoxification pathways open, so they aren't jammed up cleaning up the mess left behind by the host of environmental pollutants, trans-fats, sugars, etc. In other words, it helps "take out the trash.""
