What specific nutrient in green beans is linked to reducing levels of low-density lipoprotein (LDL) cholesterol?
The soluble fiber variety they contain.
The soluble fiber component found abundantly in green beans plays a direct role in managing cholesterol levels within the cardiovascular system. Soluble fiber works by binding with bile acids, which are produced by the liver and contain cholesterol, in the digestive tract. This binding action prevents the body from reabsorbing these bile acids; consequently, the liver must pull more cholesterol from the bloodstream to synthesize new bile acids, leading to a measurable reduction in circulating levels of low-density lipoprotein (LDL) cholesterol, frequently known as 'bad' cholesterol. This mechanism provides significant support for maintaining healthy lipid profiles, complementing the blood pressure benefits derived from the potassium content.
