There are many reasons why people turn to protein drinks—muscle building, meal replacement, as a treat while dieting or as a high-protein snack. A recent study administered by Clean Label Project had some surprising results that might just have you thinking twice about your favorite brand of protein powder.
Clean Label Project tested 134 powder drinks among 52 of the most popular brands according to Nielson and the Amazon.com best-sellers list. They were tested for more than 130 toxins including heavy metals, pesticides, BPA and other contaminants that are known carcinogens.
Of the powder drinks tested, 70 percent of them had detectable levels of lead and 74 percent had detectable levels of cadmium. Since heavy metals can exist in water and air, it’s virtually impossible to remove all of the heavy metals from the foods we eat, from fresh produce to highly processed foods like protein powders. But breathe easy: The FDA has created guidelines for safe levels for human consumption.
Of the products tested, the ones that used eggs as the protein source generally tested cleaner than the plant-based products. (Seventy-five percent of the plant-based products tested positive for lead.) What might be surprising to some is that the certified organic products tested had, on average, two times the amount of heavy metals as opposed to the non-organic ones.
What should you do?
If you’re concerned, the best thing you can do is compare levels between brands to find those with the lowest heavy metals and BPA. Look for your favorites on the list and find out where they rank—are they your best options? Or, if you’re not loyal to a specific brand, go for the top-rated ones in the study: Puori, BioChem and BodyFortress.
