re: Research: Kirstie Alley's weight loss program Organic Liaison I heard another bit of colon quackery, that over the years your colon clogs up with "stuff" that results in this huge log of mucus etc that must be cleansed so that your body can effectively absorb nutrition. They will show you pix of something claimed to be a mucus plug. Note how it follows the twisted contours of the large intestine. Note how it appears to be made of jello and horse hair. NOTE HOW THERE IS NO MEDICAL EVIDENCE THAT SUCH A THING EVEN EXISTS!
