How do saturated fats affect heart health?

Saturated fats are known to have a significant impact on heart health primarily due to their effect on cholesterol levels. Consuming high amounts of saturated fats can lead to an increase in low-density lipoprotein (LDL) cholesterol, often referred to as "bad cholesterol." Elevated levels of LDL cholesterol are associated with a higher risk of developing heart disease, as they can lead to the formation of plaque in the arteries, which can impede blood flow and potentially result in cardiovascular events such as heart attacks and strokes.

Research studies and dietary guidelines indicate that reducing saturated fat intake in favor of unsaturated fats—such as those found in olive oil, nuts, and fatty fish—can help lower LDL cholesterol levels and improve heart health. Therefore, the statement about saturated fats raising LDL cholesterol levels and subsequently increasing heart disease risk reflects a widely accepted understanding in nutritional science.
