Saturated fats are known to contribute to increased blood cholesterol levels. These fats are primarily found in animal products such as red meat and full-fat dairy, as well as some tropical oils like coconut oil. When consumed excessively, saturated fats can lead to higher levels of LDL cholesterol, which is associated with an increased risk of cardiovascular diseases. To manage cholesterol levels effectively, it is recommended to limit saturated fat intake and replace it with healthier options like unsaturated fats found in fish, nuts, and olive oil.
