What type of fat is known to contribute to higher cholesterol levels in the body?

Saturated fats are known to contribute to higher cholesterol levels in the body primarily because they can elevate low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. When consumed in excess, saturated fats can lead to a buildup of cholesterol in the arteries, increasing the risk of cardiovascular diseases.

These fats are found in various food sources, particularly animal products such as fatty cuts of meat, full-fat dairy products, and certain oils, such as coconut and palm oil. The relationship between saturated fats and cholesterol levels has been well-researched, with many health organizations recommending a reduction in saturated fat intake to improve heart health.

While trans fats also negatively affect cholesterol levels—by raising LDL and lowering high-density lipoprotein (HDL), or "good" cholesterol—saturated fats are commonly identified as the primary type of dietary fat that influences cholesterol levels directly. Polyunsaturated and monounsaturated fats, on the other hand, tend to have a beneficial effect on cholesterol profiles, helping to lower LDL levels and potentially raise HDL levels.
