It involves the intake of nutrients—such as carbohydrates, proteins, fats, vitamins, minerals, and water—that are essential for growth, energy production, and overall well-being. Good nutrition is a cornerstone of a healthy lifestyle, influencing everything from physical performance to mental health.

Promoting growth and development in children and adolescents.
Reducing the risk of chronic diseases such as heart disease, diabetes, and certain cancers.
Enhancing mental health by providing nutrients that affect brain function.
