It may be a concern for most parents, but if there was a magic food that helps a child gain height then I guess…we would all be much taller by now! Milk, however, is one of the foods that actually contains basic ingredients that help your child grow at its maximum height.
Show me your parents and I’ll show you how much you will grow!
The truth is that the maximum potential height for a child is determined by genetics. A diet rich in nutrients is, however, essential for achieving the maximum height that your child’s genes have determined for it. Such an ingredient which is also contained in milk is high organic value protein, vitamin A, vitamin D and calcium.
What is the role of milk’s nutrients?
One glass of milk (250mL) provides to a school-age child 30% of the protein, 21% of the vitamin D and ¼ of the vitamin A and the calcium of the necessary daily intake!
Are there any more findings?
Despite the methodological challenges in scientifically answering the question of whether milk actually helps height growth, it has been observed through some studies that during childhood and adolescence, those who drink or drink more cow’s milk, compared to those who do not drink or drink less cow’s milk, are 1.5-2.5 cm taller. For example, a study that monitored the growth of girls before menarche and for 7 years, revealed 2.5 cm greater height for those who consumed 3 glasses of milk compared to those who consumed <1 glass daily. The result was mainly related to milk protein.
It is also interesting to look at studies that have shown that those who drink milk have higher IGF-1 hormone concentration (insulin-like growth factor) in their blood. This is an hormone that our body produces naturally during the rapid development stages while exogenous administration of IGF-1 is also used by doctors in order to “treat” height-related issues. So despite that fact that we haven’t yet found “how”, it seems that there is something in milk that signals our body to produce more of this hormone! Similar findings have also been produced for the growth hormone which is also responsible for cell proliferation during growth.
It is worth noting that, apart from height, the mechanism described above, as it is natural during a child’s development stages, also helps with weight gain. It has been observed, however, that excessive weight or rapidly increasing weight during infancy and preschool age as well as the first primary school years, may lead to precocious puberty and result in potentially lower adult height than the maximum height determined by the child’s genes. As a result, it is important to provide the recommended milk and dairy intake (3 servings daily, be they milk, yogurt or a slice of cheese) but avoid over-eating (including over-eating of dairy) to ensure that the child maintains a healthy weight in order to achieve its maximum potential height.
To sum up
There is no food that magically helps you lose or gain weight, so there is no food that magically helps a child grow taller! For a realistic perspective on how things work, you must put genes into the picture. Beyond this reality, what you can do is care for your child’s general health: a sufficient and nutritious diet and regular physical activity. In any case, children must be raised in a way that they learn how to love and appreciate their body (and height!).
