Final answer:
Alpha-linolenic acid (ALA) and linoleic acid are considered essential fatty acids because the human body cannot synthesize them and they must be obtained from the diet. These fatty acids are necessary for normal growth, development, and overall health.
Step-by-step explanation:
Alpha-linolenic acid (ALA) and linoleic acid are considered essential fatty acids because the human body cannot synthesize them and they must be obtained from the diet. These fatty acids are necessary for normal growth, development, and overall health. While the body can convert ALA into other important omega-3 fatty acids, the conversion efficiency is low, so it is recommended to consume foods rich in ALA directly.
Excellent food sources of linoleic acid include plant oils such as corn oil and soybean oil, while rich sources of ALA include nuts, flaxseed, whole grains, legumes, and dark green leafy vegetables.
