Paying a hefty price tag for organic milk may leave wallets lighter, but a new clinical report by the American Academy of Pediatrics suggests that it may have no significant health advantages over conventional milk. 

In general, milk has the same protein, vitamin, trace mineral content, and lipids from both organically and conventionally reared cows, the report says.

One reason why consumers buy organic milk is to avoid “hormones." Yet, even if a farm supplements its cows with growth hormone or recombinant bovine somatotropin (rbST), the rbST is biologically inactive in humans and has no physiologic effect, authors of the report say in this article in the journal Pediatrics.

There is no evidence that the composition of milk (fat, protein, and lactose) is altered by treatment with rbST, nor is there any evidence that the vitamin and mineral content of milk is changed, the authors say.

In addition, rbST may have environmental benefits, the authors point out, because it allows farmers to get more milk out of their cows, which means fewer cows are needed.

According to the USDA, 187 million pounds of organic milk products were sold in August, up by nearly 10 percent from 2011. This accounted for about 4 percent of total fluid milk sales for the month. Click here to read more.

The study did find some benefits from eating organic produce.
