What role does fat play in the human body?

Fat plays a crucial role in the human body, particularly in providing energy and essential fatty acids. It is a dense source of energy, providing more calories per gram than carbohydrates or proteins. This makes it an important fuel source for the body, especially during prolonged physical activity or when carbohydrate stores are depleted.

Additionally, essential fatty acids are types of fats that the body cannot produce on its own and must be obtained through diet. These fatty acids, such as omega-3 and omega-6, are vital for various physiological functions, including the formation of cell membranes, hormone production, and maintaining overall cell health.

While fat also has roles in other areas, like supporting immune function and releasing specific hormones, its primary contributions to energy provision and supplying essential fatty acids make it a fundamental component of a balanced diet.
