Why should one avoid excessive saturated fats in the diet?

Avoiding excessive saturated fats in the diet is important primarily because they can lead to increased cholesterol levels. High intake of saturated fats is associated with raising levels of LDL cholesterol (often referred to as "bad" cholesterol) in the blood. Elevated LDL cholesterol is a significant risk factor for heart disease and stroke, as it can contribute to the buildup of plaques in the arteries, restricting blood flow and leading to various cardiovascular issues.

In contrast, while fats are indeed essential for energy and some biological functions, they must be consumed in balanced quantities, with a focus on healthier fat sources. Saturated fats do not aid in muscle building in the same way that proteins do, and they do not provide antioxidants, which are typically found in fruits and vegetables, rather than in fats. Thus, the emphasis on moderating saturated fat intake is particularly linked to heart health and managing cholesterol levels effectively.
