Which dietary component, liquid at room temperature, may help reduce blood cholesterol levels?

1. Carbohydrates

2. Proteins

3. Saturated fats

4. Unsaturated fats

The correct answer is: Unsaturated fats

Unsaturated fats are known to be beneficial for heart health, particularly in their ability to help reduce blood cholesterol levels. These fats are typically liquid at room temperature and can be found in sources such as olive oil, avocados, nuts, and fatty fish. Consuming unsaturated fats can lower levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol, while potentially increasing high-density lipoprotein (HDL) cholesterol, known as "good" cholesterol. This positive effect on cholesterol levels is primarily due to unsaturated fats' role in modifying the way the body processes lipids, thereby promoting better cardiovascular health. In contrast, carbohydrates and proteins do not have this specific effect on cholesterol levels, and saturated fats are generally associated with increased LDL levels when consumed in high amounts.
