Why saturated fatty acids are harmful for heart?

Saturated fatty acids can raise levels of LDL cholesterol (often referred to as "bad" cholesterol) in the bloodstream, which is associated with an increased risk of Heart disease. High LDL cholesterol can lead to the buildup of plaque in the arteries, a condition known as atherosclerosis, which narrows blood vessels and restricts blood flow. This can ultimately result in heart attacks or strokes. Reducing saturated fat intake and replacing it with healthier unsaturated fats may help improve heart health.
