Oils are a very useful food not only because they provide energy but also because they supply essential nutrients, particularly healthy fats and fat- soluble vitamins. Specifically, oils provide us with essential fatty acids (omega-3 and omega-6) that our body cannot produce on its own and are vital for normal body functions like building cell membranes, blood clotting, muscle movement, inflammation regulation, and hormone production. Additionally, oils contain fat-soluble vitamins such as vitamins A, D, E, and K, which are critical for various bodily processes including antioxidant protection, bone health, and blood clotting. Moreover, healthy oils like extra virgin olive oil contain antioxidants and monounsaturated fats that benefit heart health and reduce inflammation.

Thus, oils provide us with a lot of essential fatty acids, fat-soluble vitamins, and antioxidants besides energy.
