Why are saturated fats less healthy than unsaturated fats?

Saturated fats are generally considered less healthy than unsaturated fats because they can raise levels of LDL cholesterol, which is associated with an increased risk of Heart disease. In contrast, unsaturated fats, particularly monounsaturated and polyunsaturated fats, can help lower LDL cholesterol and provide essential fatty acids that the body needs. Consuming a diet higher in unsaturated fats while limiting saturated fats is linked to better overall cardiovascular health.
