Milk vs Soy
I ran across this article today, it basically says that milk is better than soy in terms of building muscle mass. I couldn't find the actual journal article for it though. This article doesn't mean anything to me since I don't drink soy milk and wasn't planning on starting, but I know soy has poked its head a couple times in other enjoy!

Here's the link to the site where I got the article in case anyone wants to see the source:


Milk beats soy for muscle gain
by Michelle Donovan
April 09, 2007
Got milk? Weightlifters will want to raise a glass after a new study found that milk protein is significantly better than soy at building muscle mass.

The study, conducted by a team of researchers at McMaster's Department of Kinesiology, was recently published in the American Journal of Clinical Nutrition. It compared how much muscle protein young men gained after completing a heavy weight workout followed by consumption of equivalent amounts of protein as either fluid skim milk or a soy drink.

"Our thinking going into the study was that milk would be better than soy," says Sarah Wilkinson, lead researcher and a graduate student in the Department of Kinesiology. "We suspected this would be the case because of work done by French researchers. However, we were really impressed by how much greater the gains in muscle protein with milk were."

The findings would suggest that if men consume only skim milk (two cups) after each of their workouts, they would gain almost twice as much muscle in 10 weeks than if they drank the same amount of protein as a soy drink.

"This is an interesting finding, since soy and milk proteins are considered to be complete proteins that are basically equivalent from a nutritional standpoint," explains Stuart Phillips, associate professor of kinesiology, who was also involved in the study. "Our findings clearly show that milk proteins are a superior source of protein in producing muscle mass gains in response to weightlifting."

Scientists also analyzed the composition of milk and soy proteins and did not find remarkable differences. At this stage, researchers are uncertain why milk proteins were so much more effective than soy. However, the two main types of proteins in milk, whey and casein, may have intrinsic properties that are advantageous for supporting muscle growth.

"The plan at this point is to follow this up with a long-term study to see if the findings from this short-term study can be replicated," says Phillips.

Funding for the study was made possible by the Canadian Institutes of Health Research (CIHR) and the US National Dairy Council.

It's not too surprising to me, really.

But on the other hand I've never seen a study funded by the National Dairy Council that didn't show milk to be a miracle worker :biglaugh:

^^ LOL. I never caught the National Dairy Council reference at first....good point :D

Good catch bro.

That's the first thing I thought of, who funded it? What other possible point could there be to a study of this nature? Who else would care? Doesn't mean the results are skewed but it does establish the economic agenda behind it.

I think it's pretty clear that for overall health, soy is much better than milk which is the issue that the NDC is trying to circumvent. I don't see the wisdom in bodybuilders who don't drink milk already to start because of this.

Correct me if I'm wrong but I believe that if not the NDC directly than the dairy industry in general is heavily supported by our tax dollars. Nice to know they're being so well spent..
