Nutrition in childhood is one of the most important factors influencing not only current health, but also long-term health and quality of life in adulthood.

A lack of certain nutrients during critical periods of development can lead to serious health problems. For example, vitamin D deficiency can cause abnormal bone development, while iodine, iron, and zinc deficiencies are associated with impaired cognitive development and lower IQ. It is therefore crucial, especially in children, to focus on the quality of their diet and specific nutritional needs at different stages of their development.
