What dietary habit is linked to vitamin A deficiency in children?

Low consumption of fresh vegetables is linked to vitamin A deficiency in children because many vegetables, particularly leafy greens and orange or yellow vegetables, are rich sources of provitamin A carotenoids. These carotenoids can be converted by the body into vitamin A, which is essential for numerous physiological functions including vision, immune system performance, and skin health. When children do not consume enough fresh vegetables, they miss out on these important nutrients, which can lead to deficiencies.

Inadequate dietary intake of vitamin A will result particularly in the absence of sources that include dairy products, liver, and certain fish, but the emphasis on vegetables is critical because they provide not only carotenoids but also other essential vitamins and minerals that help in overall growth and development. Hence, dietary habits that limit access to fresh vegetables can significantly impact vitamin A status in children, posing a risk for deficiency and its associated complications.
