Fiber-rich foods significantly impact heart disease risk by lowering cholesterol levels and promoting digestive health. Soluble fiber, found in foods such as oats, legumes, and fruits, can help reduce LDL (bad) cholesterol, which contributes to heart disease. Additionally, a high-fiber diet encourages regular bowel movements and can aid in weight management, factors crucial in preventing cardiovascular conditions. Furthermore, fiber-rich foods often contain beneficial vitamins and minerals that enhance overall health, making them an essential component of a heart-healthy diet.
