What effect does saturated fat have on HDL and LDL levels?

Saturated fat has a well-documented effect on cholesterol levels in the body. Specifically, it is known to raise levels of low-density lipoprotein (LDL), often referred to as "bad" cholesterol. Elevated LDL levels are associated with an increased risk of cardiovascular diseases, as they can lead to the buildup of plaque in the arteries.

Moreover, saturated fats can also influence high-density lipoprotein (HDL), commonly known as "good" cholesterol. While it is sometimes thought that saturated fats might raise HDL, the evidence is mixed and does not establish a direct or consistent benefit. Therefore, it's important to understand that the primary impact of saturated fat is its tendency to raise LDL levels, while its effect on HDL is less predictable.

This knowledge is crucial for understanding dietary recommendations, especially in the context of maintaining healthy cholesterol levels and overall cardiovascular health.
