Why are unsaturated fats considered beneficial?

Unsaturated fats are considered beneficial primarily because they promote heart health. These fats can help lower levels of LDL (low-density lipoprotein) cholesterol, often referred to as "bad" cholesterol, while increasing HDL (high-density lipoprotein) cholesterol, known as "good" cholesterol. This shift is important as it helps reduce the risk of cardiovascular diseases, such as heart attacks and strokes.

Unsaturated fats, which are found in sources like olive oil, avocados, nuts, and fatty fish, provide essential fatty acids that the body cannot produce on its own, such as omega-3 and omega-6 fatty acids. These fats contribute to various bodily functions, including inflammation regulation, brain health, and hormone production.

In contrast, fats high in trans fatty acids, which are generally considered harmful, are linked to increased cholesterol levels and higher risks of heart disease. Unsaturated fats, therefore, stand out in promoting overall cardiovascular health and maintaining better cholesterol profiles.
