Which type of dietary fat should be limited to maintain heart health?

Saturated fat should be limited to maintain heart health because it has been shown to raise levels of LDL cholesterol, commonly known as "bad" cholesterol, in the blood. Elevated LDL cholesterol is a significant risk factor for heart disease and stroke, as it can lead to the buildup of plaque in the arteries, which narrows them and reduces blood flow. Health guidelines often recommend replacing saturated fats with unsaturated fats, which can help improve cholesterol levels and overall heart health. This approach includes incorporating more sources of unsaturated fats, such as those found in fish, nuts, seeds, and plant oils, which can promote better cardiovascular health. Limiting saturated fat intake is a key dietary strategy advocated by health organizations to support heart health.
