American Association of Family and Consumer Sciences (AAFCS) Practice Test

Which dietary source primarily contains unsaturated fats that can help lower cholesterol?

1. Red meat

2. Butter

3. Olive oil

4. Coconut oil

The correct answer is: Olive oil

Olive oil is a primary source of unsaturated fats, particularly monounsaturated fats, which are known to have a positive impact on cholesterol levels. These healthy fats can help reduce levels of LDL (low-density lipoprotein) cholesterol, often referred to as "bad" cholesterol, while potentially increasing HDL (high-density lipoprotein) cholesterol, known as "good" cholesterol. This balancing effect on cholesterol levels is beneficial for cardiovascular health. Olive oil also contains antioxidants, such as vitamin E and polyphenols, which can contribute to its health benefits. This makes it a staple in heart-healthy diets, like the Mediterranean diet, where it is used in cooking and dressings. In contrast, red meat, butter, and coconut oil are sources of saturated fats, which can raise LDL cholesterol levels and are generally associated with greater cardiovascular risk when consumed in excess. Although saturated fats can form a part of a balanced diet, their role in affecting cholesterol levels is less favorable compared to the unsaturated fats found in olive oil.
