What is chicken used for in the body?

It seems you're asking about the nutritional value of chicken rather than how it's used in the human body. Chicken is a great source of many essential nutrients:

* Protein: Chicken is a complete protein, meaning it contains all the essential amino acids our bodies need to build and repair tissues.

* Vitamin B12: Essential for the formation of red blood cells and the function of the nervous system.

* Niacin (B3): Important for energy metabolism and the health of skin, hair, and nerves.

* Selenium: An antioxidant that helps protect cells from damage.

* Iron: Essential for red blood cell production and oxygen transport.

* Zinc: Important for immune function, wound healing, and cell growth.

* Phosphorus: A mineral that plays a role in bone health, energy production, and cell signaling.

However, chicken is not actually "used" in the body in the way you might think. Your body breaks down the chicken into its individual nutrients, which are then absorbed and used for various functions.

So, instead of "chicken" being used, it's the nutrients within chicken that are vital for the body.
