Big Milk farms out PhDs to do their dirty work.

Big Milk's onslaught of advertisements designed to look like newspaper articles continued last week with this full page feature in Canwest papers.

I'm sure the Dairy Farmers of Canada were thrilled with Dr. Brian Roy, director of the Centre for Muscle Metabolism and Biophysics at Brock University, who happily perpetuated a dairy myth - that it magically helps with weight loss. Dr. Roy was quoted as saying,

"While it may seem surprising, milk can even help people lose weight. Studies report calcium rich diets can prove effective as a weight loss regime. Those studies have also shown diets rich in milk and milk products provide an extra boost to weight reduction."
Oh really Brian?

Even the meta-analysis penned by Dr. Susan Barr, milk industry stalwart, who according to comments in my blog recently told the UBC medical school class that lactose intolerance was exaggerated and that everyone should drink a glass of milk a day, in a dairy sponsored and paid for symposium concluded,
"the data available from randomized trials of dairy product or calcium supplementation provide little support for an effect in reducing body weight or fat mass."
Want to know who else doesn't think the data on dairy and weight loss are impressive? America's answer to the Dairy Farmers of Canada, the National Dairy Council (the heavyweights responsible for the milk moustache and Got Milk? ad campaigns), who withdrew their assertion that drinking milk would help with weight loss when the Federal Trade Commission threatened them. Under the FTC's glare the Council stated they'd refrain from the ads,
"until further research provides stronger, more conclusive evidence of an association between dairy consumption and weight loss"
That was in May 2007. Looking at Medline since May 2007 there has only been one study published that specifically looked at the effects of dairy consumption patterns on weight loss. That study's conclusion?
"Our results do not support the hypothesis that a higher dairy consumption protects against weight gain and development of metabolic disturbances in a Dutch elderly population."
So to summarize. Big Milk itself admitted to the Federal Trade Commission that to date the suggestion that dairy contributes to weight loss is preliminary at best - a point agreed upon by Dr. Susan Barr, and a point the vast majority of studies on dairy consumption and weight conclude is in fact false as they demonstrate no benefit, yet here we have an advertisement published in the Canadian Press that includes a statement by a misinformed professor that the industry itself knows isn't even remotely conclusively true.

I guess if pressed they could state that, "he said it, not us".

Like I said before, if you're a physician or a researcher and Big Milk comes a'knockin' don't answer the call and if you see an "article" about the benefits of Dairy that calls itself a "joint venture", remember it's just an advertisement and given Big Milk's track record in advertising, it should be read with tremendous skepticism.

(Brian if you're reading this I know you're partial to Zemel's research as you cite it a great deal in your review on chocolate milk as a recovery drink. To learn more about Zemel have a gander as the Centre for Science in the Public Interest's report on him and his patented, yes patented, research)
