Monounsaturated fats, such as those found in olive oil and avocados, can help reduce cholesterol levels when consumed in moderation. These healthy fats can positively influence the balance of lipoproteins in the body, increasing high-density lipoprotein (HDL) cholesterol, which helps remove low-density lipoprotein (LDL) cholesterol from the bloodstream. Incorporating these fats into the diet can be part of a heart-healthy eating plan, reducing the risk of heart disease when combined with other lifestyle factors like regular exercise and a balanced diet rich in whole foods.
