Oils are a very useful food because, as well as energy, they provide a lot of fat‑soluble vitamins (especially vitamins A, D, E and K).

Why oils are useful

  • Oils are energy-dense, giving more calories per gram than carbohydrates or proteins.
  • Many common vegetable oils help the body absorb fat‑soluble vitamins such as A, D, E and K from other foods.

Vitamins you get from oils

  • Vitamin E is particularly abundant in many vegetable oils and acts as an antioxidant in the body.
  • By improving absorption of these fat‑soluble vitamins, oils support functions like vision (vitamin A), bone health (vitamin D), blood clotting (vitamin K), and protection from oxidative damage (vitamin E).
