Final answer:
To prevent anemia in children, increasing vitamin C intake is beneficial, as it aids iron absorption, a vital element for blood health.
Step-by-step explanation:
The dietary practice that is beneficial for preventing anemia in children is increasing vitamin C intake. Vitamin C aids in the absorption of iron from the intestine, which is crucial since iron is a key component in the formation of hemoglobin in the blood. Anemia, particularly iron deficiency anemia, can be caused by insufficient iron in the diet, and it is especially common among children and adolescents. Foods high in vitamin C, such as citrus fruits, green vegetables, tomatoes, and berries, should be consumed to improve iron absorption.
It is important to note that anemia can also be related to other vitamin deficiencies, like vitamin B12 and folate, and sometimes increased consumption of iron-rich foods such as red meat, legumes, and spinach, or taking an iron supplement might be necessary. Conversely, reducing iron intake, avoiding dairy products, and eliminating protein-rich foods are not recommended for preventing anemia, as proteins enhance iron absorption and dairy products provide other essential nutrients despite not being high in iron.
