What type of dietary fat is considered harmful to heart health?

Saturated fats are considered harmful to heart health primarily because they can raise levels of LDL cholesterol (often referred to as "bad" cholesterol) in the bloodstream. High levels of LDL cholesterol are associated with an increased risk of heart disease, as they can lead to the buildup of plaque in the arteries, which narrows them and can ultimately result in cardiovascular problems such as heart attacks and strokes.

While some dietary fats, such as monounsaturated and polyunsaturated fats, are beneficial and can actually help improve heart health by lowering LDL levels and increasing HDL cholesterol (the "good" cholesterol), saturated fats do not have this positive effect. Omega-3 fatty acids, a type of polyunsaturated fat found in fish and flaxseeds, are particularly known for their heart-protective properties.

Understanding the distinction between these types of fats is crucial for promoting overall cardiovascular health. Making informed dietary choices, particularly regarding the intake of saturated fats, is essential for maintaining a healthy heart and reducing the risk of heart disease.
