How do the bile acid sequestrants in kale function to help lower LDL cholesterol levels?

By binding bile acids in the digestive system, forcing the liver to pull more cholesterol from the bloodstream

Kale supports cardiovascular wellness through several mechanisms, including managing cholesterol via specialized compounds called bile acid sequestrants. These sequestrants work within the digestive tract by binding to bile acids. Bile acids are synthesized in the liver using existing cholesterol found in the bloodstream. When these acids are bound by the sequestrants, they cannot be reabsorbed by the body and are instead eliminated through waste. To compensate for this loss of bile acids, the liver is compelled to synthesize new ones, which requires pulling more cholesterol directly out of the circulating bloodstream, thereby resulting in a net reduction of harmful LDL cholesterol levels.
