Verified step by step guidance1
Step 1: Understand the concept of linoleic acid. Linoleic acid is an essential omega-6 polyunsaturated fatty acid that cannot be synthesized by the human body and must be obtained through the diet. It is commonly found in plant-based oils.
Step 2: Analyze the composition of the given options. Butter and coconut oil are primarily composed of saturated fats, which contain very little to no linoleic acid. Olive oil contains monounsaturated fats, with only a small amount of linoleic acid.
Step 3: Recognize that sunflower oil is a rich source of linoleic acid. Sunflower oil is known for its high content of polyunsaturated fats, particularly linoleic acid, making it a dietary source of this essential fatty acid.
Step 4: Compare the options based on their fatty acid profiles. Sunflower oil stands out as the best source of linoleic acid among the options provided.
Step 5: Conclude that sunflower oil is the correct answer based on its nutritional composition and high linoleic acid content.
