Final answer:
Option C is correct option. The type of dietary fiber that helps lower heart disease risk is soluble dietary fiber, which can reduce blood cholesterol and glucose levels. Foods rich in soluble fiber include oats, apples, and beans.
Step-by-step explanation:
The specific type of dietary fiber that is recognized to help lower heart disease risk is soluble dietary fiber. Soluble fiber includes nondigestible carbohydrates that dissolve in water to form a gel-like substance as it moves through the gastrointestinal tract. This type of fiber can slow down the absorption of glucose, which may help to minimize insulin spikes and thus reduce the risk of type 2 diabetes. Additionally, soluble fiber has been associated with the ability to lower blood cholesterol levels, which is a key factor in reducing the risk of heart disease.
Good sources of soluble fiber include foods like oats, apples, and beans, which are known to provide this heart-healthy nutrient. Consuming these foods can contribute to a diet that supports cardiovascular health and may prevent chronic diseases related to the heart and blood vessels. It is recommended to include a variety of these sources in your diet to gain the associated health benefits.
It is noteworthy that while both insoluble and soluble fibers have health benefits, it is the soluble fiber that specifically contributes to heart health by lowering cholesterol and regulating blood glucose levels.
