Which type of fat is associated with an increased risk of heart disease?

Saturated fat is linked to an increased risk of heart disease because it can raise levels of LDL (low-density lipoprotein) cholesterol in the blood, which is often referred to as "bad" cholesterol. High LDL cholesterol is a known risk factor for cardiovascular issues, including heart disease and stroke. Foods that typically contain high levels of saturated fat include fatty cuts of meat, full-fat dairy products, and many processed foods. Reducing the intake of saturated fats and replacing them with healthier fats can help manage cholesterol levels and reduce the risk of heart disease.

In contrast, unsaturated fats, including both monounsaturated and polyunsaturated fats, are generally considered heart-healthy because they can help to lower LDL cholesterol levels and provide essential fatty acids that the body needs. Trans fats, while also associated with heart disease, are a type of unsaturated fat that has been hydrogenated and are often found in processed foods, but the focus on saturated fat aligns more with conventional dietary guidelines regarding heart health.
