How Fiber Flushes Cholesterol From Your Blood

[00:00:00]Can the fiber you eat after a meal actually scrub cholesterol out of your bloodstream?

[00:00:04]It sounds like magic, but it is pure biology.

[00:00:08]First, soluble fiber binds to bile acids inside your intestines, trapping them so they are excreted through your stool.

[00:00:15]Second, because these bile acids are lost, your liver is forced to replenish them.

[00:00:20]To do this, the liver must use LDL cholesterol from your blood as a raw material for bile acid synthesis.

[00:00:26]Third, as the liver pulls more cholesterol from your circulation to create new bile, the concentration of bad cholesterol in your blood significantly drops.

[00:00:35]To see these results, aim to consume at least 5 g of soluble fiber from sources like vegetables or oats with every meal.

[00:00:42]The key to lowering your LDL levels is preventing bile acid reabsorption through fiber intake.
