What type of fat should be limited in a healthy diet?

In a healthy diet, it is advisable to limit saturated fats and trans fats due to their association with an increased risk of heart disease and other health concerns. Saturated fats, which are found in animal products like meat and full-fat dairy, as well as in some plant oils, can raise levels of LDL cholesterol (often referred to as "bad" cholesterol) in the blood. High levels of LDL cholesterol can lead to a greater risk of cardiovascular issues.

Trans fats, often found in partially hydrogenated oils used in many processed or fried foods, not only raise LDL cholesterol levels but also lower HDL cholesterol (the "good" cholesterol). This combination contributes to a higher risk of coronary artery disease.

In contrast, monounsaturated fats and polyunsaturated fats, including omega-3 fatty acids, are beneficial for heart health. They can improve cholesterol levels, reduce inflammation, and are linked to a lower risk of heart disease. Therefore, focusing on reducing saturated and trans fats while including healthier fats is crucial for maintaining overall health.
