I think it's supposed to suck up excess fats(which then are excreted..), which then can't go clogging your arteries. Not very scientific, sorry!

The most common cause of coronary heart disease (CHD) is the clogging of arteries, called atherosclerosis. The stuff that builds up on the inside of arteries is a fatty deposit, mostly made of cholesterol. Now, cholesterol is naturally made by the liver, and plays an important role in our health and wellbeing. It is when there is too much cholesterol in our system that problems start to occur. The digestion of fiber literally pulls the cholesterol out of the blood stream and into the digestive tract to help. That's it in a nutshell, but if you want more detailed info, here it is: http://health.howstuffworks.com/diseases-conditions/cardiovascular/cholesterol/foods-that-lower-cholesterol2.htm
