Here's why:

* Vitamins are organic compounds that are essential for various bodily functions. They can't be synthesized by the body and must be obtained through diet.

* Minerals are inorganic elements found in nature and essential for various bodily functions. They are also obtained through diet.

Fatty acids are organic molecules made up of a long chain of carbon and hydrogen atoms. They are macronutrients, meaning they are needed in large quantities for energy and various bodily functions.

Some fatty acids are essential, meaning the body can't produce them and they must be obtained from food. Examples include omega-3 and omega-6 fatty acids.

Therefore, fatty acids are a distinct category of nutrients, separate from vitamins and minerals.
