Which type of fat is generally considered healthier for the heart?

Unsaturated fats are considered healthier for the heart due to their positive effects on cholesterol levels and overall cardiovascular health. They can help lower levels of low-density lipoprotein (LDL) cholesterol, which is often referred to as "bad" cholesterol, and can also increase levels of high-density lipoprotein (HDL) cholesterol, known as "good" cholesterol. Unsaturated fats are typically found in plant-based oils, nuts, seeds, avocados, and fatty fish.

In contrast, saturated fats, commonly found in red meat, butter, and full-fat dairy products, can raise LDL cholesterol levels, potentially increasing the risk of heart disease when consumed in excess. Trans fats, often present in processed foods and baked goods, are harmful as they not only raise LDL cholesterol but also lower HDL cholesterol, making them particularly detrimental to heart health. Hydrogenated fats, which are often used to improve shelf life in foods, can also contain trans fats and have similar negative effects on cardiovascular health. Thus, the heart-healthy choice is to incorporate unsaturated fats into the diet while minimizing saturated and trans fats.
