Final answer:
Animal products are not a source of unsaturated fat; they typically contain saturated fats. Unsaturated fats, which are healthier for the heart, are found in plant-based oils such as olive, corn, and canola oils. Therefore correct option is E
Step-by-step explanation:
Among the listed sources, the one that is not a source of unsaturated fat is animal products. Unsaturated fats are primarily found in plant-based oils, such as olive oil, corn oil, canola oil, and vegetable oil. These types of oils are liquid at room temperature due to the presence of unsaturated fatty acids, which have one or more double bonds between the carbon atoms.
On the other hand, animal products typically contain a higher proportion of saturated fats. These are generally solid at room temperature and can contribute to the formation of plaque in arteries when consumed in excess. It's important to distinguish between unsaturated and saturated fat sources, as unsaturated fats are considered to be healthier for heart health.
