Why are essential fatty acids important for health?

Essential fatty acids are important for health mainly because they play a critical role in brain function. They are required in the formation of cell membranes and are involved in various physiological processes including neurotransmission and the synthesis of signaling molecules. The human brain, which is composed of about 60% fat, relies on these fatty acids for proper structure and function. A deficiency in essential fatty acids can lead to cognitive issues and impairments in mental health.

It's important to clarify that essential fatty acids cannot be synthesized by the body, which is why they are termed "essential." They must be obtained through diet, highlighting their importance beyond just serving as nutrients, but as fundamental components for overall health, particularly neurological health.
