The July 2010 issue of Consumer Reports (CR) magazine investigates protein drinks with not very flattering findings:
… [O]ur investigation, including tests at an outside laboratory of 15 protein drinks, a review of government documents, and interviews with health and fitness experts and consumers, found most people already get enough protein, and there are far better and cheaper ways to add more if it’s needed. Some protein drinks can even pose health risks, including exposure to potentially harmful heavy metals, if consumed frequently. All drinks in our tests had at least one sample containing one or more of the following contaminants: arsenic, cadmium, lead, and mercury. Those metals can have toxic effects on several organs in the body.
It’ll take some time to fully dissect the findings. Obviously, nobody needs to ingest unsafe levels of heavy metals. But 12 of the 15 did not contain unacceptable levels of any heavy metals in a full three (3) servings daily. Of the 3 that did show unacceptable levels, again, it was only at 3 servings daily, not one or 2. Only one product had levels of arsenic above the proposed USP limit. Further, the USP limits are based on a person weighing only 110 pounds — considerably less than many if not most protein shake drinkers. READ MORE »
