But now, Canadian researchers found out that children who don’t drink cow milk may have insufficient levels of vitamin D. Scientists have tracked vitamin D blood levels in many children younger than six.
About 10 percent of them drank only milk from a source other than cows. There are many factors that affect levels of vitamin D: age, sex, weight, vitamin D supplementation, skin pigmentation, and hours of outdoor play.
Yet, it is fully believed that children who don’t drink cow milk but drink other kinds of milk will have lower vitamin D levels. Cow milk is guaranteed to have vitamin D while other kinds of milk are not guaranteed to. This is the top reason why you give your child cow milk regularly.
