Parents who choose non-dairy drinks like soy, almond, or rice milk instead of cow’s milk are likely stunting their children’s growth, new research reveals.
According to a study published in The American Journal Of Clinical Nutrition, kids who consume one daily cup of dairy alternatives tend to be about 0.4 centimeters (0.15 inches) shorter than kids who drink cow’s milk.
And the more non-dairy milk a child drinks, the greater that height disparity becomes. So, for example, kids who consume three daily cups of non-dairy milk tend to be about 1.5 centimeters (0.6 inches) shorter.
“Not a tiny difference” for young children, lead researcher Dr. Jonathon Maguire of St. Michael’s Hospital in Toronto told CNN.
Maguire added that he found the increase in height disparity with increased non-dairy consumption to be particularly remarkable:
“It’s not like if you’re not consuming cow’s milk, you’re a little shorter. It’s more like if you are consuming non-cow’s milk, with each cup that a child consumes, that child on average appears to be a little bit smaller, a little shorter. That’s a bit surprising.”
Maguire and company found these height differences by tracking the growth of more than 5,000 Canadian children with an even gender split between the ages of two and six. About five percent drank only non-dairy alternatives, while about 84 percent exclusively drank cow’s milk (of the remaining children, about eight percent drank both and about three percent drank neither).
Sure enough, the non-dairy drinkers ended up shorter.
Nevertheless, the study has raised a number of questions and concerns.
Should the team have considered other factors besides just their subjects’ milk consumption? Some researchers say yes.
Do the non-dairy drinkers eventually catch up to the dairy drinkers over time? Maguire isn’t yet sure.
Why might non-dairy alternatives cause kids to end up shorter? Maguire isn’t yet sure of that either, but the study suggests that non-dairy alternatives may not stimulate kids’ insulin-like growth factors — proteins essential in a number of development functions — in the same way that cow’s milk can.
Whatever the reason, Maguire is confident that non-dairy alternatives are nutritionally inferior and that their industry should be more tightly regulated, lest parents think that those products provide the same benefits as cow’s milk.
