Expectant Mothers Need Milk's Vit D

I just read this at WebMD.

"xpectant mothers who don't drink milk aren't getting enough vitamin D -- and it's affecting their babies, a Canadian study shows. Babies born to mothers who do not drink milk weigh a bit less than those born to moms who do...
..Koski's team studied 279 healthy pregnant women and their newborns. The difference in weight wasn't large. Kids born to mothers who did not drink milk averaged 7.5 pounds, versus the 7.8-pound babies born to the average milk drinker.
...here are about 2.25 micrograms of vitamin D in a cup of milk. The Koski study, Hollis says, shows that for each daily microgram of vitamin D a mother consumes, her baby's birth weight will increase by 11 grams -- more than a third of an ounce. That's a little less than one extra ounce of birth weight for every daily cup of milk a mother drinks."

Interesting, but I also suspect that the milk companies will cash in on this.
