Bad news for fans of protein smoothies?

Like many fitness enthusiasts, protein smoothies have been part of my diet for many years. Adequate protein intake helps to maintain and build muscle when combined with strength training. I was alarmed when recent lab tests revealed 47% of 160 protein powders contained high levels of lead and cadmium. Neither do anything for muscle health but are toxic to our organs and brains.

Plant-based powders are marketed as the healthiest choice, however, the tests revealed those made from soy, rice, peas, and other plants, contained three times more lead than whey-based powders. Similarly, organic powders had three times more lead and twice the amount of cadmium compared to their non-organic counterparts.

To avoid legal entanglements, the Clean Label Project, which tested the powders didn’t release information regarding specific brands, likely confusing consumers. Some brands, including the one I use, carry the NSF Certified for Sport seal. The NSF website says products they certify contain no unsafe levels of contaminants and the contents match what is printed on the label. That said, protein powders, while convenient, aren’t necessary to be strong and fit.
