A healthy outside starts from the inside. Growth is a trait of childhood and a sensitive sign of a child’s nutritional health. Childhood is a time when the foundation is built for the full development of the body’s organs, functions, and senses and when a child blossoms physically, socially, and mentally.

Children who are taught healthier eating habits are less prone to serious health-related problems and live longer.

This chapter focuses on the most essential vitamins and minerals that shall not be missed out in any case.
