Which type of fat is primarily found in animal products and raises LDL cholesterol levels?

The type of fat that is primarily found in animal products and is known to raise LDL cholesterol levels is saturated fat. Saturated fats are typically solid at room temperature and are prevalent in foods such as red meat, butter, cheese, and other dairy products.

When consumed, saturated fats can lead to an increase in the concentration of low-density lipoprotein (LDL) cholesterol in the blood. Elevated LDL cholesterol is associated with a higher risk of cardiovascular diseases, as it can accumulate in the walls of arteries, leading to atherosclerosis.

In contrast, monounsaturated fats, which can be found in plant-based oils, avocados, and nuts, generally have a heart-healthy effect and can actually help to reduce LDL cholesterol levels. Trans fats, often found in processed foods, can also raise LDL cholesterol levels but are distinct from saturated fats in terms of their chemical structure and effects on health. Polyunsaturated fats, found in fatty fish, nuts, and seeds, tend to lower LDL cholesterol and are beneficial for heart health.
