Here's a breakdown of why:
* Nutrition encompasses the study of how the body takes in, absorbs, utilizes, and eliminates nutrients from food.
* Nutrients are the substances in food that provide the body with energy, building blocks for growth and repair, and help regulate various bodily functions.
* Growth regulation involves the processes controlled by nutrients that determine how the body grows and develops.
* Tissue maintenance refers to the ongoing repair and renewal of tissues in the body, which is facilitated by nutrients.
While other fields like biochemistry and physiology contribute to understanding the processes involved, nutrition specifically focuses on the relationship between food and its impact on the body's growth, maintenance, and overall health.
