Final answer:
Milk anemia in toddlers is caused by excessive milk consumption, which can lead to a deficient and imbalanced diet. Skim milk, fruit juice, increased milk intake, or increased fruit intake alone are not direct causes of milk anemia.
Step-by-step explanation:
The cause of milk anemia in toddlers is drinking excessive amounts of milk, often at the expense of a varied and balanced diet. This is most commonly seen when toddlers consume large quantities of whole cow's milk and exclude other nutrient-rich foods from their diet.
Drinking skim milk or fruit juice, or increasing the intake of milk and fruits alone, does not directly cause milk anemia. However, if these are the only sources of nutrition and the child is not getting a balanced diet, it can contribute to the development of anemia.
It's important for toddlers to have a diverse diet that includes a variety of foods from different food groups to ensure they are getting all the necessary nutrients.
