The healthiest type of fat for the body is unsaturated fat, particularly monounsaturated and polyunsaturated fats. These fats are found in foods like olive oil, avocados, nuts, and fish. Unsaturated fats can help reduce bad cholesterol levels, lowering the risk of heart disease and promoting overall cardiovascular health. In contrast, saturated fats and trans fats, commonly found in processed foods, can contribute to various health issues when consumed in excess. Including healthy fats in moderation is essential for a balanced diet and overall well-being.
