Why are omega-3 fatty acids classified as essential fats in the context of human nutrition?
Answer
The human body cannot produce these fats on its own
Omega-3 fatty acids are deemed 'essential' because they represent a class of polyunsaturated fats that are biologically necessary for human health, yet the body lacks the enzymatic pathways required to synthesize them internally from precursor molecules. Consequently, these vital fats, which are known for their role in supporting cardiovascular health, must be acquired directly through dietary consumption. Salmon is an excellent source of these fats, providing a direct mechanism for meeting the body's requirement for these critical nutrients.
