High levels of which type of fat can lead to cardiovascular issues?

Saturated fats are commonly linked to cardiovascular issues because they can raise levels of LDL (low-density lipoprotein) cholesterol in the blood. Elevated LDL cholesterol is a major risk factor for developing atherosclerosis, where plaque builds up in the arteries, leading to heart disease and stroke. The consumption of higher amounts of saturated fats, often found in animal products like meat and full-fat dairy, as well as some tropical oils, has been shown in several studies to contribute to an increase in heart-related health problems.

Understanding the context of fat types is important; monounsaturated fats and polyunsaturated fats, often found in foods like avocados, nuts, and fish, are generally considered heart-healthy as they can help reduce LDL cholesterol levels and potentially lower the risk of heart disease. Omega-3 fats, a type of polyunsaturated fat, are specifically known for their protective cardiovascular benefits, helping to lower triglyceride levels and reduce inflammation. Thus, while different types of fats have varying effects on cardiovascular health, the evidence supports that high intake of saturated fats is particularly detrimental.
