Final answer:
Plant oils are especially rich in the essential micronutrient vitamins, including fat-soluble types, and provide essential fatty acids like omega-3 and omega-6 that are critical for health.
Step-by-step explanation:
Plant oils are a rich source of the micronutrient called vitamins. These oils often contain fat-soluble vitamins such as vitamin E and essential fatty acids that are vital for human health. The fatty acids include omega-3 alpha-linolenic acid and omega-6 linoleic acid which are essential and must be obtained through our diet, as the body cannot synthesize them.
In addition to providing essential fatty acids, plant oils typically contain a mixture of monounsaturated, polyunsaturated, and even some saturated fatty acids. Notably, fat-soluble vitamins are a class of vitamins that must be obtained from food sources, as they play a crucial role in many enzymatic functions within the body, acting as coenzymes. Examples of sources rich in these nutrients include soybean oil, corn oil, flaxseed, walnuts, avocado oil, and olive oil.
