Which type of fat is associated with raising total blood cholesterol and LDL cholesterol?

Saturated fats are known to raise total blood cholesterol and low-density lipoprotein (LDL) cholesterol levels. This effect is significant because high levels of LDL cholesterol are associated with an increased risk of cardiovascular diseases, including heart attacks and strokes. Saturated fats are typically found in animal products such as meat, butter, and cheese, as well as some plant oils, like coconut oil and palm oil.

The mechanisms behind this include saturated fats stimulating the liver to produce more LDL cholesterol and potentially inhibiting the body's ability to remove LDL from the bloodstream. This understanding stresses the importance of moderating saturated fat intake in a balanced diet to maintain optimal cholesterol levels and promote heart health. Other types of fats, such as polyunsaturated and monounsaturated fats, are generally considered heart-healthy and do not have the same detrimental effects on cholesterol levels. Omega-3 fatty acids, in particular, are beneficial for heart health and are often highlighted for their positive roles in lowering triglycerides and overall inflammation.
