Why are unsaturated fats considered healthier than saturated fats?

Unsaturated fats are considered healthier than saturated fats primarily because they can help reduce cholesterol levels in the body. Unsaturated fats are typically found in plant-based oils, nuts, seeds, and fatty fish, and these fats can positively influence heart health by lowering levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. This reduction in LDL cholesterol is associated with a lower risk of heart disease and stroke.

In contrast, saturated fats, which are commonly found in animal products and some tropical oils, can raise LDL cholesterol levels. High levels of LDL cholesterol are linked to an increased risk of cardiovascular problems. Therefore, incorporating unsaturated fats into your diet is generally advised as a way to promote better heart health and overall well-being.

Understanding this distinction is important in nutritional science, as dietary choices can have significant implications for long-term health.
