Question

Quizplus · Accepted Answer

Chronic inadequate dietary intake of vitamin A is the most common factor contributing to vitamin A deficiency worldwide. This is particularly prevalent in low-income countries where access to a variety of nutrient-rich foods is limited. Although contaminated drinking water and poor immune system functioning can also contribute to the problem, they are not as significant as a lack of dietary intake. While sunlight is important for vitamin D synthesis, it is not a significant factor in vitamin A deficiency.
