What is the stated nutritional benefit of increasing fiber intake from fruits, vegetables, and whole grains?
Answer
It can help lower LDL ('bad') cholesterol levels
A key component of a heart-healthy diet involves consuming ample amounts of fiber, which is abundant in fruits, vegetables, and whole grains. This dietary fiber plays a significant physiological role in managing the body's cholesterol balance. Specifically, it aids in reducing the levels of low-density lipoprotein (LDL) cholesterol, often termed 'bad' cholesterol, which is the component responsible for contributing to the formation of arterial plaque. While fiber also provides other benefits, its documented role in managing circulating LDL is a cornerstone of cardiovascular dietary advice.
