What role does soluble fiber play in the body?

Increases blood sugar levels
Promotes muscle growth
Helps lower blood cholesterol levels
Improves digestion of protein

The correct answer is: Helps lower blood cholesterol levels

Soluble fiber plays a significant role in the body by helping to lower blood cholesterol levels. This type of fiber dissolves in water to form a gel-like substance in the digestive tract. This gel can bind to cholesterol molecules and bile acids, which are made from cholesterol, and assist in their removal from the body. As a result, when soluble fiber is consumed, it can reduce the absorption of cholesterol into the bloodstream, helping to improve cardiovascular health and reduce the risk of heart disease. In addition to cholesterol management, soluble fiber also aids in regulating blood sugar levels, as it slows down the digestion and absorption of carbohydrates. This function can help prevent spikes in blood sugar, which is beneficial for individuals managing diabetes or those at risk of developing it. While soluble fiber does improve overall digestion, its primary recognized benefits are linked to cholesterol reduction and blood sugar control.
