Hepatic digestive fluid allowing fat absorption.
Bile is a hepatic secretion stored in the gallbladder and discharged into the duodenum during meals. It emulsifies lipids to make them accessible to pancreatic lipases.
Bile contains bile salts (cholesterol derivatives), bilirubin, cholesterol, and phospholipids. Bile salts emulsify lipids into micelles, increasing the contact surface for lipases. After fat absorption, they are reabsorbed in the ileum and recycled (enterohepatic cycle). Soluble fibers capture bile salts and reduce cholesterol.
Emulsification of dietary lipids to enable digestion and absorption.
Soluble fibers (oats, apple) reduce LDL-cholesterol by capturing bile salts.
Soluble fibers lower cholesterol by intercepting bile salts before their recycling.
