Dietary changes that can help manage cholesterol levels include increasing the intake of soluble fiber through foods like oats, beans, and fruits, which help lower LDL cholesterol. Incorporating healthy fats, such as those from avocados, nuts, and olive oil, instead of saturated fats found in red meat and full-fat dairy, can also improve cholesterol profiles. Reducing processed and sugary foods is vital, as they can contribute to weight gain and adversely affect cholesterol levels. Overall, a balanced diet plays a key role in managing cholesterol.
