Consumer Reports did an analysis of protein powders and pre-made shakes for their July issue. In addition to protein and vitamins, we're also ingesting arsenic, lead, and other heavy metals. One of the biggest culprits was EAS and Muscle Milk. They say that their sample size was three servings a day. Unfortunately, for me that's not too much of a stretch since I had a shake before working out, a protein bar, and one before bed.
The magazine article is coming out in July, but here's a preview of it's contents and the chart that lists which powders/drinks had what.
I'm so mad. Is it such a stretch to ask for food that isn't contaminated with something?
