What is one major function of dietary fats in the body?

Dietary fats play several vital roles in the body, and one major function is providing energy and supporting cell growth. Fats are a concentrated source of energy, yielding about 9 calories per gram, which is more than double the amount provided by carbohydrates or proteins. This energy is essential for various bodily functions and activities, including maintaining body temperature and supporting metabolic processes.

Additionally, fats are crucial for supporting cell growth. They form an integral part of cell membranes, contributing to their structure and fluidity. This is important for the proper functioning of cells, including nutrient absorption and communication between cells.

The other responses, while related to nutrition and bodily functions, do not encapsulate the primary role of dietary fats as effectively as the chosen answer. For instance, while fats are involved in hormone production, the primary function highlighted in the question focuses on energy provision and cell growth.
