Excessive intake of saturated fats is linked to which health issue?

The association between excessive intake of saturated fats and an increased risk of heart disease is well-documented in nutrition science. Saturated fats are typically found in animal products, such as meat and dairy, as well as some plant oils. When consumed in large amounts, saturated fats can lead to elevated levels of low-density lipoprotein (LDL) cholesterol in the bloodstream. High LDL cholesterol is a major risk factor for atherosclerosis, a condition characterized by the build-up of plaques in arteries, which can ultimately result in heart attacks or strokes.

Furthermore, numerous health organizations recommend limiting saturated fat intake to maintain cardiovascular health, highlighting the link between high saturated fat consumption and coronary heart disease. Research suggests that replacing saturated fats with unsaturated fats can enhance heart health and reduce overall risk.

The other options do not accurately connect saturated fat intake to health effects. For example, lowered immunity is not directly linked to saturated fat intake, and improved digestion is usually associated with beneficial fiber sources rather than fats. Additionally, excessive saturated fat intake is generally related to weight gain, not decreased body weight.
