Which of the following is NOT an example of unsaturated fats?

Butter is not an example of unsaturated fats; it is primarily composed of saturated fats. Unsaturated fats are typically found in plant-based oils and fats, which are usually liquid at room temperature. Olive oil, canola oil, and corn oil are all examples of unsaturated fats, which include both monounsaturated and polyunsaturated types.

Saturated fats, like those found in butter, have been associated with increasing levels of LDL cholesterol in the blood, which can contribute to cardiovascular disease. In contrast, unsaturated fats can help reduce LDL cholesterol levels and have beneficial effects on heart health when consumed in moderation. This understanding is crucial in nutrition, particularly when discussing dietary recommendations for improving cardiovascular health.
