Medical experts at St. Michael's Hospital in Toronto, Canada have concluded that children between the ages of two and five should drink at least half a liter of cow's milk daily..

Pediatrician Jonathon Magier, who works at the hospital, together with colleagues examined 1311 children aged two to five years.. Experts have found that when a child does not consume enough milk, vitamin D decreases in the body.. Whereas excessive consumption of milk helps to reduce the level of iron in the blood of children, which is an indispensable element.

Lack of iron inhibits mental development, leads to the development of anemia. Children have a weakened immune system, they become more prone to fatigue, they have a decrease in the level of the hormone produced by the thyroid gland.

When it comes to setting the optimal daily milk intake for children, doctors say they are already tired of vague recommendations..

It should be noted that Jonathon Magire's conclusions are based on the results of blood tests of his young patients, who came to see him between 2008 and 2010..

Initially, the doctor asked the permission of the parents, after which he asked them to fill out a special questionnaire..

The questionnaire required to indicate the amount of milk that the child drinks per day.. In addition, to maintain the purity of the study, the pediatrician also took into account other information that, for example, could affect the blood level of vitamin D or iron at the time of sampling from the patient.
