2. Subjects prone to vitamin A deficiency

Vitamin A deficiency occurs when the amount of vitamin A reserves runs out and the amount of vitamin A inge is insufficient. Those prone to vitamin A deficiency are those with vitamin A deficiency diets, bacterial or parasite infections, and malnourished children,…

  • Due to the diet of vitamin A deficiency: due to the body's inavitamin self-synthesis of vitamin A, therefore the entire vitamin A is provided by food. If the meal has foods poor in vitamin A and lack of fat will reduce the absorption of vitamin A. For young children, breast milk is an important source of vitamin A, so breastfeeding is very easy to lead to vitamin A deficiency.
  • Bacterial and parasite diseases: bacterial infections such as measles, diarrhea or respiratory inflammation,… cause vitamin A deficiency or loss due to the increased demand for vitamin A in the body to protect against pathogens. The most common intestinal parasite infection is ringworm that reduces the absorption of vitamin A.
  • Protein malnutrition: malnourished children are often accompanied by vitamin A deficiency. Because a lack of protein will affect metabolism, transportation and use of vitamin A in the body. In addition, if there is a lack of certain micro-substances such as zinc can also affect vitamin A metabolism in the body.
