Fiber sticks to cholesterol and removes it with the excretory process.
Source: "Your body does not actually digest dietary fiber. Instead, soluble fiber sits in your large intestine where it is fermented by bacteria. During fermentation, some free fatty acids are produced. The process is not entirely understood, but one of these fatty acids travels to your liver and tells it to produce less cholesterol, resulting in a reduction of total cholesterol levels."
Try eating an apple everyday..an easy way to get fiber.
