There are no "food groups" within the human body. "Food groups" are categories of foods we *eat* that provide different nutrients.

Here are the main food groups:

* Fruits: Rich in vitamins, minerals, and fiber.

* Vegetables: Rich in vitamins, minerals, and fiber.

* Grains: Provide carbohydrates, fiber, and some nutrients.

* Protein Foods: Include meat, poultry, fish, beans, eggs, and nuts. Provide protein, iron, and other nutrients.

* Dairy: Provides calcium, vitamin D, and other nutrients.

* Oils: Provide essential fatty acids, but should be consumed in moderation.

These food groups are important for a balanced diet that provides all the nutrients your body needs to function properly.
