Dietary factors influencing cholesterol levels include the intake of saturated fats, trans fats, and soluble fiber. Foods high in saturated fats, such as red meat and full-fat dairy, can raise low-density lipoprotein (LDL) cholesterol levels. Conversely, incorporating more whole grains, fruits, and vegetables can promote healthier cholesterol levels. Maintaining a balanced diet with healthy fats—such as those found in nuts, avocados, and fish—supports cardiovascular health.
