Which of the following statements is true about essential fatty acids?

Essential fatty acids (EFAs) are critical for various bodily functions but cannot be synthesized by the body; therefore, they must be obtained through dietary sources. The term "essential" indicates that these fatty acids are vital for health, as the body requires them for processes such as cell membrane structure, inflammation regulation, and brain function.

The two primary types of essential fatty acids are omega-3 and omega-6 fatty acids. They play a crucial role in maintaining a healthy balance of fats in the body, contributing to heart health and proper immune function. Since the body does not have the capability to produce these fatty acids on its own, they must be consumed in sufficient amounts through food sources such as fish, nuts, seeds, and certain oils.

While some fatty acids can be synthesized from other fats, the essential fatty acids are specifically those that must come from diet. Thus, the assertion that they must be consumed through diet is accurate and underscores their importance in nutrition.
