How do saturated fats generally affect blood cholesterol levels?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

In general, saturated fatty acids tend to elevate both LDL ("bad") and total blood cholesterol levels. While many saturated fats have this effect, it is important to note that their impact can vary; for instance, stearic acid is considered neutral and does not raise or lower blood cholesterol levels.12

Conversely, replacing saturated fats in the diet with unsaturated fats—such as monounsaturated or polyunsaturated fatty acids—typically results in a reduction of LDL and total blood cholesterol. Because excess consumption of saturated fats is linked to dyslipidemia and an increased risk of cardiovascular disease, maintaining a balanced diet is essential for heart health.21
