The healthiest type of fat for heart health is often considered to be monounsaturated fats. These fats, found in foods like olive oil, avocados, and nuts, can help lower bad cholesterol levels (LDL) while raising good cholesterol levels (HDL). Additionally, they provide important nutrients and have anti-inflammatory properties. Replacing saturated and trans fats in the diet with monounsaturated fats can reduce the risk of heart disease and improve overall cardiovascular health, making them a beneficial choice for those prioritizing heart health.
