Various types of fats can significantly impact cholesterol levels. Saturated and trans fats can raise low-density lipoprotein (LDL) cholesterol, commonly known as "bad" cholesterol, increasing the risk of heart disease. On the other hand, unsaturated fats, particularly polyunsaturated and monounsaturated fats found in foods like avocados, nuts, and fatty fish, can help lower LDL cholesterol and raise high-density lipoprotein (HDL) cholesterol, or "good" cholesterol. Balancing fat intake and prioritizing healthier fats while minimizing harmful ones is crucial for maintaining healthy cholesterol levels and supporting heart health.
